GMAT Flashcards: Quant, Verbal & Data Insights Decisions

Build quick recall for the current GMAT with 300 original cards across Quantitative Reasoning, Verbal Reasoning, and Data Insights. The deck focuses on reusable concepts and decisions; full-length practice belongs in official or properly licensed question banks.

What the cards map

  • Quant maps numeric forms, terms, rules, and formulas to their meaning, conditions, or use. Short scenarios ask for the operation, equation, or answer check that fits.
  • Verbal maps passage and argument cues to purpose, scope, evidence, inference, reasoning flaws, and evaluation moves.
  • Data Insights maps targets, constraints, source and display cues, metrics, and evidence states to the interpretation or decision they support. It covers Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis.

Learning order

The mixed sequence keeps all three sections in rotation. Quant foundations come before algebra, models, and strategy checks; passage reading comes before argument evaluation; shared data literacy comes before the five Data Insights formats. Closely related prompts are spaced apart so one card does not cue the next.

Current-format boundary

This deck has no geometry lessons or formula drills, Sentence Correction, or the retired Integrated Reasoning section. It also excludes timing, scoring, test-center policy, full passages, large data sets, and response-pattern tricks.

Every card is an original compact concept or decision prompt. No official or competitor questions, answer choices, explanations, mark schemes, curriculum text, logos, or trade dress were copied or adapted. See the official GMAT exam content and Data Insights preparation guidance for the current exam boundary.

  1. Kart 1

    Soru

    Which numerator-and-denominator operation creates an equivalent fraction?

    Cevap

    Multiply or divide the numerator and denominator by the same nonzero number. The fraction's value stays unchanged.

  2. Kart 2

    Soru

    What does data sufficiency ask you to determine?

    Cevap

    Whether the information guarantees one answer. You usually don’t need to calculate that answer.

  3. Kart 3

    Soru

    How do you form a passage's main idea?

    Cevap

    Combine the passage's central topic with its main claim about that topic. The answer should cover the whole passage at the right level.

  4. Kart 4

    Soru

    What does multiplying a decimal by 10ⁿ do when n is a positive integer?

    Cevap

    It moves the decimal point n places to the right. Dividing by 10ⁿ moves it n places left.

  5. Kart 5

    Soru

    What makes information sufficient for a value question?

    Cevap

    It forces exactly one value for the target. Different values that satisfy all conditions make it insufficient.

  6. Kart 6

    Soru

    How do you identify the passage's primary purpose?

    Cevap

    Name what the author is doing with the topic: explaining, comparing, challenging, defending, or proposing. Keep content and action together.

  7. Kart 7

    Soru

    How do you find p percent of a quantity q?

    Cevap

    Compute (p/100) × q. Translate “of” as multiplication.

  8. Kart 8

    Soru

    How can two valid cases prove insufficiency?

    Cevap

    Make the cases produce different answers to the question. One clean counterexample pair is enough.

  9. Kart 9

    Soru

    How do you determine a paragraph's role?

    Cevap

    Connect the paragraph to what comes before and after it. Decide whether it introduces, supports, qualifies, contrasts, applies, or concludes the larger discussion.

  10. Kart 10

    Soru

    A total of 45 is split in the ratio 2:3. What are the two parts?

    Cevap

    18 and 27. The five ratio units are worth 45 ÷ 5 = 9 each.

  11. Kart 11

    Soru

    Why can an integer restriction change sufficiency?

    Cevap

    It removes noninteger possibilities. A range containing many real numbers may contain only one integer.

  12. Kart 12

    Soru

    When is a product of signed factors negative?

    Cevap

    Provided no factor is zero, an odd number of negative factors gives a negative product, while an even number gives a positive product. If any factor is zero, the product is zero.

  13. Kart 13

    Soru

    How should two data-sufficiency statements be tested initially?

    Cevap

    Test each statement independently against the stem. Do not carry information from one statement into the other.

  14. Kart 14

    Soru

    What makes an integer greater than 1 prime?

    Cevap

    It has exactly two positive divisors: 1 and itself.

  15. Kart 15

    Soru

    What should you do first on a detail question?

    Cevap

    Return to the relevant lines and read their local context. Memory tends to preserve the topic while blurring qualifications.

  16. Kart 16

    Soru

    What is the divisibility rule for 2?

    Cevap

    The last digit must be even: 0, 2, 4, 6, or 8.

  17. Kart 17

    Soru

    How do you test whether a fact is relevant?

    Cevap

    Connect it to the requested target. A true fact that does not narrow the target adds no decision value.

  18. Kart 18

    Soru

    How far may a reading inference go beyond the text?

    Cevap

    Only as far as the text strongly supports. Prefer the smallest justified step and reject claims needing outside knowledge.

  19. Kart 19

    Soru

    Why is prime factorization useful in GMAT arithmetic?

    Cevap

    It exposes divisibility, factors, greatest common factors, least common multiples, and perfect powers.

  20. Kart 20

    Soru

    What must happen before quantities with different units are combined?

    Cevap

    First confirm that their dimensions are compatible, then convert them to a common unit. Keep the unit attached through the calculation to catch mismatches.

  21. Kart 21

    Soru

    How do you apply a passage principle to a new case?

    Cevap

    Extract the principle's required conditions, then test whether the new case has them. Surface similarity isn't enough.

  22. Kart 22

    Soru

    Which relationship connects distance, rate, and time?

    Cevap

    Distance = rate × time. Rearrange only after the units are compatible.

  23. Kart 23

    Soru

    How do you find a least common multiple from prime factorizations?

    Cevap

    Take every prime that appears, using the largest exponent present.

  24. Kart 24

    Soru

    How do you multiply powers with the same base?

    Cevap

    Add the exponents: aᵐ × aⁿ = aᵐ⁺ⁿ.

  25. Kart 25

    Soru

    How is a weighted average computed?

    Cevap

    Divide the total weighted value by the total weight. For groups, use group size as the weight unless another weight is given.

  26. Kart 26

    Soru

    What should a quick passage map record?

    Cevap

    Each paragraph's role and major viewpoint, plus the passage's overall direction. Record structure, not a sentence-by-sentence summary.

  27. Kart 27

    Soru

    What does the principal square root symbol √x return?

    Cevap

    For real x ≥ 0, it is the nonnegative number whose square is x. For example, √9 = 3, not ±3.

  28. Kart 28

    Soru

    When can bounds replace exact arithmetic?

    Cevap

    When the bounds separate the viable decisions. Stop once every value in the interval leads to the same choice.

  29. Kart 29

    Soru

    How do you keep viewpoints separate?

    Cevap

    Attach each claim to its speaker: author, critic, researcher, or group. Track agreement, disagreement, and any later qualification.

  30. Kart 30

    Soru

    How do “sum,” “product,” and “quotient” translate into algebra?

    Cevap

    They mean addition, multiplication, and division, respectively.

  31. Kart 31

    Soru

    How do you reduce a fraction to lowest terms?

    Cevap

    Divide the numerator and denominator by their greatest common factor.

  32. Kart 32

    Soru

    What evidence should determine the author's tone?

    Cevap

    Evaluative words, qualifications, and the treatment of competing views. Topic alone doesn't establish approval, concern, or skepticism.

  33. Kart 33

    Soru

    When should rounding usually occur?

    Cevap

    At the end, unless estimation already settles the decision. Early rounding can move a result across a cutoff.

  34. Kart 34

    Soru

    How do you convert a terminating decimal to a fraction?

    Cevap

    Write the digits over the matching power of 10, then reduce. For example, 0.375 = 375/1000 = 3/8.

  35. Kart 35

    Soru

    When should you stop calculating in a sufficiency problem?

    Cevap

    As soon as uniqueness is proved or disproved. More arithmetic cannot change the sufficiency decision.

  36. Kart 36

    Soru

    How do you spot an out-of-scope answer?

    Cevap

    It introduces a person, period, cause, or consequence the passage doesn't address. Being reasonable doesn't make it textually supported.

  37. Kart 37

    Soru

    What is the percent-change formula?

    Cevap

    For original > 0, percent change = (new − original) / original × 100%. Percent change from zero is undefined; negative baselines require context-specific interpretation.

  38. Kart 38

    Soru

    What makes information sufficient for a yes-or-no question?

    Cevap

    It forces the same yes-or-no answer in every valid case. The underlying value may still vary.

  39. Kart 39

    Soru

    What preserves a ratio when its quantities are scaled?

    Cevap

    Multiplying or dividing both terms by the same nonzero factor preserves the ratio.

  40. Kart 40

    Soru

    How do you reject a main-idea answer with the wrong scope?

    Cevap

    Compare it with the whole passage. A detail-only answer is too narrow; a claim extending beyond the passage is too broad.

  41. Kart 41

    Soru

    Why should you track whether a variable is positive, negative, or zero?

    Cevap

    Sign controls valid cases and operations. Squaring can hide sign, and division requires a nonzero denominator.

  42. Kart 42

    Soru

    How do you simplify subtraction of a negative number?

    Cevap

    Change it to addition: a − (−b) = a + b.

  43. Kart 43

    Soru

    Whose purpose matters in a primary-purpose question?

    Cevap

    The passage author's purpose. A theory or researcher may be described at length without representing what the author ultimately wants to do.

  44. Kart 44

    Soru

    When is the on-screen calculator most useful?

    Cevap

    For tedious arithmetic after the setup is clear. It does not replace choosing the right relationship or denominator.

  45. Kart 45

    Soru

    In Data Sufficiency, what stem information applies when testing either statement?

    Cevap

    Everything in the question stem. Stem facts remain active for each statement and for the combination.

  46. Kart 46

    Soru

    What is the divisibility rule for 3?

    Cevap

    The sum of the digits must be divisible by 3.

  47. Kart 47

    Soru

    What does a transition paragraph often do?

    Cevap

    It closes one line of thought and sets up the next. Its role depends on both sides, not only on its first sentence.

  48. Kart 48

    Soru

    When is a proxy measure useful?

    Cevap

    When evidence shows it reliably tracks the target for the intended decision. Correlation may support prediction, but it proves neither causation nor suitability on its own.

  49. Kart 49

    Soru

    How do you find a greatest common factor from prime factorizations?

    Cevap

    Take each shared prime to the smaller exponent.

  50. Kart 50

    Soru

    What is the arithmetic mean?

    Cevap

    The sum of the values divided by the number of values.

  51. Kart 51

    Soru

    What units should a rate have?

    Cevap

    One quantity per another, such as kilometers per hour. The denominator tells you what the rate is measured against.

  52. Kart 52

    Soru

    How do you divide powers with the same nonzero base?

    Cevap

    Subtract the exponents: aᵐ ÷ aⁿ = aᵐ⁻ⁿ.

  53. Kart 53

    Soru

    What makes a paraphrase faithful to a passage detail?

    Cevap

    It preserves the original meaning, scope, and certainty in different words. Shared keywords alone don't make it accurate.

  54. Kart 54

    Soru

    How do you recover a total from an average?

    Cevap

    Total = average × number of values.

  55. Kart 55

    Soru

    How do you choose between two plausible reading inferences?

    Cevap

    Choose the one with the tighter textual chain and fewer assumptions. Plausibility in the real world is secondary.

  56. Kart 56

    Soru

    What quick check can catch a calculator-entry error?

    Cevap

    Estimate the order of magnitude and direction first. An exact result far outside that range deserves another look.

  57. Kart 57

    Soru

    How do you simplify a square root with a perfect-square factor?

    Cevap

    Factor out the perfect square. For example, √72 = √(36 × 2) = 6√2.

  58. Kart 58

    Soru

    What makes a new example parallel to one in the passage?

    Cevap

    The same logical relationship. Match cause, contrast, exception, or function rather than shared subject matter.

  59. Kart 59

    Soru

    When can work rates be added?

    Cevap

    Add the stated constant rates when the workers operate simultaneously without interfering with one another. At 1/4 and 1/6 job per hour, together they complete 5/12 job per hour.

  60. Kart 60

    Soru

    What is the denominator in a percent comparison?

    Cevap

    The stated reference value. “A as a percent of B” means A divided by B, then multiplied by 100.

  61. Kart 61

    Soru

    How do you translate “5 less than x”?

    Cevap

    x − 5. The phrase “less than” reverses the spoken order.

  62. Kart 62

    Soru

    In Data Sufficiency, what should you check before testing values?

    Cevap

    The full domain. Honor stated restrictions and implicit ones such as positive lengths or nonzero divisors before judging sufficiency.

  63. Kart 63

    Soru

    How do you add fractions with different denominators?

    Cevap

    Rewrite them with a common denominator, then add the numerators. For example, 2/3 + 1/4 = 8/12 + 3/12 = 11/12.

  64. Kart 64

    Soru

    How do you distinguish description from argument in a passage?

    Cevap

    Description presents what happened or what a view says; argument gives reasons to accept, reject, or revise a claim.

  65. Kart 65

    Soru

    How should you compare decimals with different lengths?

    Cevap

    Append trailing zeros and compare place by place. For example, compare 0.47 with 0.4700, which are equal.

  66. Kart 66

    Soru

    How should combined statements be evaluated?

    Cevap

    Intersect their constraints with the stem. The combination is sufficient only if every remaining case gives one answer.

  67. Kart 67

    Soru

    How do you find common ground between two viewpoints?

    Cevap

    Look for the narrow claim both accept, even if they disagree about its cause, importance, or implications.

  68. Kart 68

    Soru

    How do you solve a proportion such as a/b = c/d?

    Cevap

    Cross-multiply to get ad = bc, provided b and d are nonzero.

  69. Kart 69

    Soru

    How is average speed computed?

    Cevap

    Total distance divided by total time. It is not usually the simple mean of the segment speeds.

  70. Kart 70

    Soru

    What does |x| represent?

    Cevap

    The nonnegative distance from x to 0 on the number line.

  71. Kart 71

    Soru

    Why are strongly emotional tone descriptions often wrong?

    Cevap

    They overstate measured academic prose. Match the answer's intensity to the author's actual language.

  72. Kart 72

    Soru

    What is the divisibility rule for 4?

    Cevap

    The number formed by the last two digits must be divisible by 4.

  73. Kart 73

    Soru

    Can the ordinary percent-change formula be applied directly when the original value is zero or negative?

    Cevap

    No. The ordinary GMAT rule assumes original > 0. Change from zero is undefined, and a negative baseline requires context-specific interpretation.

  74. Kart 74

    Soru

    Why can a true statement still be a wrong answer?

    Cevap

    It may not answer the question asked. Check the task—main idea, detail, inference, role, or purpose—before checking truth.

  75. Kart 75

    Soru

    When must a weighted average lie between its component values?

    Cevap

    When every weight is nonnegative and the total weight is positive. The average then lies between the smallest and largest component values.

  76. Kart 76

    Soru

    How do you express an integer n divided by d with remainder r?

    Cevap

    n = dq + r, where q is an integer and 0 ≤ r < d for positive d.

  77. Kart 77

    Soru

    What does an inequality usually provide?

    Cevap

    A range, not a unique value. It can still be sufficient if the question asks whether a threshold is crossed.

  78. Kart 78

    Soru

    How should you handle an EXCEPT detail prompt?

    Cevap

    Verify four statements against the passage and select the one that isn't supported. Keep the reversed task visible while checking each choice.

  79. Kart 79

    Soru

    How should you set up a unit conversion?

    Cevap

    Multiply by a conversion factor equal to 1, placing units so the unwanted unit cancels.

  80. Kart 80

    Soru

    Can two individually insufficient statements remain insufficient together?

    Cevap

    Yes. They may repeat the same limitation or still leave multiple valid answers.

  81. Kart 81

    Soru

    For a positive base, how do you simplify a power raised to another power?

    Cevap

    Multiply the exponents: (aᵐ)ⁿ = a^(mn).

  82. Kart 82

    Soru

    When can you infer that an author accepts a claim?

    Cevap

    When the author endorses it directly or relies on it without distancing language. Merely reporting another person's view isn't endorsement.

  83. Kart 83

    Soru

    How should successive percentage changes be combined?

    Cevap

    Multiply their factors. A 10% rise followed by a 10% fall gives 1.10 × 0.90 = 0.99, a 1% net fall.

  84. Kart 84

    Soru

    What are compatible numbers in estimation?

    Cevap

    Nearby numbers chosen to make mental arithmetic easy, such as 203 ÷ 9.9 ≈ 200 ÷ 10 = 20.

  85. Kart 85

    Soru

    Which constraints are easy to overlook in a word problem?

    Cevap

    Countability, positivity, distinctness, and capacity limits. Translate each noun and rule into a usable constraint.

  86. Kart 86

    Soru

    How do you state the exact disagreement between two viewpoints?

    Cevap

    Identify one claim that one side accepts and the other rejects. Don't substitute a topic that only one side discusses.

  87. Kart 87

    Soru

    How do you represent three consecutive integers?

    Cevap

    n, n + 1, and n + 2 for an integer n.

  88. Kart 88

    Soru

    How do percentage points differ from percent change?

    Cevap

    Percentage points are the direct difference between percentages. Moving from 20% to 25% is 5 points and a 25% relative increase.

  89. Kart 89

    Soru

    What is a reversed-relationship trap?

    Cevap

    It swaps cause and effect, support and conclusion, or the positions of two viewpoints while reusing familiar passage language.

  90. Kart 90

    Soru

    How do you multiply two fractions?

    Cevap

    Multiply numerator by numerator and denominator by denominator, canceling common factors when convenient.

  91. Kart 91

    Soru

    How do direct and inverse proportion differ?

    Cevap

    Direct: y = kx; inverse: y = k/x for x ≠ 0.

  92. Kart 92

    Soru

    How do you recover an original value after a percentage increase?

    Cevap

    Divide the new value by the growth factor. After a 20% increase, original = new ÷ 1.20.

  93. Kart 93

    Soru

    When should absolute wording raise suspicion?

    Cevap

    When the passage is qualified. Words such as always, never, entirely, and impossible require equally strong textual support.

  94. Kart 94

    Soru

    What should you identify first in Data Sufficiency?

    Cevap

    The exact target and answer type. Decide whether the stem asks for a value, a comparison, or a yes-or-no result.

  95. Kart 95

    Soru

    What ending makes an integer divisible by 5 or by 10?

    Cevap

    A last digit of 0 or 5 gives divisibility by 5; a last digit of 0 gives divisibility by 10.

  96. Kart 96

    Soru

    How should a Data Sufficiency condition be handled?

    Cevap

    Translate it into a precise constraint before testing sufficiency. Keep it separate from the conclusion you want.

  97. Kart 97

    Soru

    How do you reject a half-right answer?

    Cevap

    Test every part of it. One accurate clause can't rescue a second clause that distorts the passage or exceeds its scope.

  98. Kart 98

    Soru

    When you convert a positive measurement to a smaller linear unit, what happens to its numerical value?

    Cevap

    It increases. Multiply by the number of smaller units in one larger unit.

  99. Kart 99

    Soru

    DS example: Is x > 5? Statement: x > 3. Is the statement sufficient?

    Cevap

    No. Both x = 4 and x = 6 satisfy the statement, but they answer the stem differently.

  100. Kart 100

    Soru

    What is a⁰ when a is nonzero?

    Cevap

    1. The nonzero-base condition matters because 0⁰ is not assigned this rule.
  101. Kart 101

    Soru

    Which claim is the argument trying to establish?

    Cevap

    The main conclusion. Find the claim supported by the other statements, then check that it answers the argument's central issue.

  102. Kart 102

    Soru

    When should the two statements be combined?

    Cevap

    When neither statement is sufficient alone. Use both constraints at once and test the remaining possibilities.

  103. Kart 103

    Soru

    A positive number rounds to 8.2 to the nearest tenth. What interval contains it?

    Cevap

    8.15 ≤ x < 8.25. The lower endpoint rounds up to 8.2; the upper endpoint rounds to 8.3.

  104. Kart 104

    Soru

    What should you check when the conclusion changes populations?

    Cevap

    Whether the evidence applies to the new population. Results from volunteers, specialists, or one age group may not transfer to everyone.

  105. Kart 105

    Soru

    How should test values be chosen in Data Sufficiency?

    Cevap

    Choose valid values that probe boundaries, signs, and distinct outcomes. Random easy values can miss the deciding case.

  106. Kart 106

    Soru

    How do you translate “A is 30% more than B”?

    Cevap

    A = 1.30B. The percentage is based on B.

  107. Kart 107

    Soru

    When can one equation involving two variables be sufficient for a target?

    Cevap

    When every valid solution gives the same target value, even if neither variable is unique. For example, x + y = 10 is sufficient to determine x + y.

  108. Kart 108

    Soru

    What does a correlation establish by itself?

    Cevap

    Only that two things vary together. It doesn't establish which one causes the other or whether a third factor causes both.

  109. Kart 109

    Soru

    How do you divide by a nonzero fraction?

    Cevap

    Multiply by its reciprocal. For example, 3/5 ÷ 2/7 = 3/5 × 7/2.

  110. Kart 110

    Soru

    Why is a ratio often insufficient for an absolute value?

    Cevap

    A ratio fixes relative size but usually leaves the scale free. Many proportional pairs can share the same ratio.

  111. Kart 111

    Soru

    What is the divisibility rule for 9?

    Cevap

    The sum of the digits must be divisible by 9.

  112. Kart 112

    Soru

    What matters most when applying a sample result to a population?

    Cevap

    Representativeness. The sample must resemble the target population on traits that could affect the result.

  113. Kart 113

    Soru

    What should you check after solving a squared equation?

    Cevap

    Check every allowed root. If positive and negative roots produce different target answers, the information is insufficient.

    Soru

    What does a negative exponent mean?

    Cevap

    It takes the reciprocal: a⁻ⁿ = 1/aⁿ for nonzero a.

  115. Kart 115

    Soru

    Which baseline makes a comparison informative?

    Cevap

    The baseline relevant to the claim. Compare the outcome with what would otherwise have happened, not merely with an unrelated earlier figure.

  116. Kart 116

    Soru

    What risk appears when an equation factors into multiple branches?

    Cevap

    Each branch may create valid cases. Test all branches against the stem before deciding sufficiency.

  117. Kart 117

    Soru

    How can you compare two positive fractions quickly?

    Cevap

    Compare their cross-products. For a/b and c/d with positive denominators, compare ad with bc.

  118. Kart 118

    Soru

    What may be assumed from a Data Sufficiency diagram?

    Cevap

    Only marked or stated facts. Do not infer scale, equality, perpendicularity, or midpoint status from appearance.

  119. Kart 119

    Soru

    What multiplier represents a p percent increase or decrease?

    Cevap

    Use 1 + p/100 for an increase and 1 − p/100 for a decrease.

  120. Kart 120

    Soru

    Which statements count as evidence?

    Cevap

    The statements offered as reasons to accept another claim. Evidence may be factual or assumed for the argument, even if it isn't proven in real life.

  121. Kart 121

    Soru

    Can a mean determine an individual observation?

    Cevap

    Not by itself. A mean fixes the total, but different sets can have that total unless more constraints apply.

  122. Kart 122

    Soru

    What weakens a move from past evidence to a present claim?

    Cevap

    A relevant change over time. New technology, prices, rules, or behavior can make the earlier evidence a poor guide.

  123. Kart 123

    Soru

    A value becomes 96 after a 20% increase. What was the original value?

    Cevap

    1. Divide the final value by the growth multiplier: 96 ÷ 1.2 = 80.
  124. Kart 124

    Soru

    How do extreme valid cases help in Data Sufficiency?

    Cevap

    They expose whether the target can change. Test the smallest, largest, or boundary cases allowed by the conditions.

  125. Kart 125

    Soru

    How do you test for reverse causation?

    Cevap

    Ask whether the alleged effect could instead cause the alleged cause. Productive teams may meet more because they are productive, not the reverse.

  126. Kart 126

    Soru

    Must a sufficient statement make every variable unique?

    Cevap

    No. It only needs to make the requested target unique, even if other variables remain undetermined.

  127. Kart 127

    Soru

    A price rises 20% and then falls 20%. Does it return to its original value?

    Cevap

    No. The multipliers give 1.20 × 0.80 = 0.96, so the final price is 4% below the original.

  128. Kart 128

    Soru

    Why can a voluntary survey be biased?

    Cevap

    People who choose to respond may differ from those who don't. Strong opinions or extra interest can distort the sample.

  129. Kart 129

    Soru

    How do you expand a(b + c)?

    Cevap

    ab + ac. The outside factor multiplies every term inside the parentheses.

  130. Kart 130

    Soru

    What should the final Data Sufficiency decision describe?

    Cevap

    Which information set guarantees an answer. It should not report the target’s numerical value.

  131. Kart 131

    Soru

    What is the goal when solving a linear equation?

    Cevap

    Isolate the variable by applying equivalent operations to both sides.

  132. Kart 132

    Soru

    DS example: Is integer n even? Statement: n = 7. Is the statement sufficient?

    Cevap

    Yes. It guarantees one answer—no. A statement can be sufficient even when that answer is negative.

  133. Kart 133

    Soru

    When must an inequality sign reverse?

    Cevap

    When both sides are multiplied or divided by a negative number.

  134. Kart 134

    Soru

    What must be checked before comparing two groups?

    Cevap

    Whether they differ in other relevant ways. Age, experience, starting level, or incentives may explain the outcome instead.

  135. Kart 135

    Soru

    When is substitution preferable to elimination in a two-equation system?

    Cevap

    Use substitution when one variable is already isolated or easy to isolate; use elimination when coefficients cancel easily.

  136. Kart 136

    Soru

    What should you build before analyzing Multi-Source Reasoning material?

    Cevap

    A quick source map. Note what each tab or document contains, who produced it, and the relevant date or scope.

  137. Kart 137

    Soru

    How do you separate background from evidence?

    Cevap

    Ask whether the statement supports a claim. Background sets context; evidence does logical work in moving the argument toward a conclusion.

  138. Kart 138

    Soru

    Which algebraic terms can be combined?

    Cevap

    Terms with the same variable part and exponents. For example, 3x² and −5x² combine, but 3x² and 3x do not.

  139. Kart 139

    Soru

    When should you read the Multi-Source Reasoning question?

    Cevap

    Before a deep read of every source. The question tells you which details deserve attention.

  140. Kart 140

    Soru

    What is a reliable first step for an equation containing several fractions?

    Cevap

    Multiply every term by the least common denominator, then solve the simpler equation.

  141. Kart 141

    Soru

    Why does source provenance matter?

    Cevap

    It defines what a claim can support. An internal forecast and an audited result do not carry the same evidentiary weight.

  142. Kart 142

    Soru

    What should you test when evidence comes from a different setting?

    Cevap

    Whether the settings differ in a way that affects the result. A finding from one market, school, or climate may not carry over unchanged.

  143. Kart 143

    Soru

    What does an “and” compound inequality require?

    Cevap

    The overlap of both solution sets. A value must satisfy both conditions.

  144. Kart 144

    Soru

    What should you compare before combining claims from two sources?

    Cevap

    Their population, period, units, and definitions. Matching labels can hide different scopes.

  145. Kart 145

    Soru

    How can a third factor undermine a causal claim?

    Cevap

    It may explain both events, so their correlation no longer establishes a direct causal link by itself. Hot weather can raise both cold-drink sales and pool attendance.

  146. Kart 146

    Soru

    What do one, zero, or infinitely many solutions mean for two linear equations in two variables?

    Cevap

    The lines intersect once, are parallel and distinct, or are the same line, respectively.

  147. Kart 147

    Soru

    How should records from separate sources be linked?

    Cevap

    Use a shared key with the same meaning in both sources, such as product code and month. Do not join on a vague label alone.

  148. Kart 148

    Soru

    How do you factor 6x + 9?

    Cevap

    3(2x + 3). Pull out the greatest common factor.

  149. Kart 149

    Soru

    When does nonresponse threaten a survey result?

    Cevap

    When nonrespondents may answer differently from respondents. A high response count doesn't fix a systematic missing group.

  150. Kart 150

    Soru

    What is the first step when two sources seem inconsistent?

    Cevap

    Compare definitions, dates, units, and aggregation levels. Many apparent conflicts come from mismatched frames.

  151. Kart 151

    Soru

    When can you use the zero-product property?

    Cevap

    After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.

  152. Kart 152

    Soru

    How does an inference differ from a stated fact?

    Cevap

    A fact appears directly in a source; an inference must follow from the sources without an extra assumption.

  153. Kart 153

    Soru

    Does a higher percentage by itself prove a higher count?

    Cevap

    No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.

  154. Kart 154

    Soru

    What does an “or” compound inequality require?

    Cevap

    The union of the solution sets. A value may satisfy either condition or both.

  155. Kart 155

    Soru

    What does a blank or omitted value establish?

    Cevap

    Only that the value is not provided. It does not establish zero, no change, or failure.

  156. Kart 156

    Soru

    How do you recognize an intermediate conclusion?

    Cevap

    It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.

  157. Kart 157

    Soru

    What should you do before writing equations for a two-quantity word problem?

    Cevap

    Define each variable with its unit, then translate one independent relationship per equation.

  158. Kart 158

    Soru

    Why should cross-source events be placed in time order?

    Cevap

    Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.

  159. Kart 159

    Soru

    When should candidate solutions be checked in the original equation?

    Cevap

    Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.

  160. Kart 160

    Soru

    How can switching from one measured outcome to another create a gap?

    Cevap

    Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.

  161. Kart 161

    Soru

    What makes a source relevant to a claim?

    Cevap

    It supplies evidence for a required link in the claim. Related background alone is not enough.

  162. Kart 162

    Soru

    How do you solve a factored polynomial inequality reliably?

    Cevap

    Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.

  163. Kart 163

    Soru

    Does happening first prove causation?

    Cevap

    No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.

  164. Kart 164

    Soru

    How can you spot an unsupported cross-source conclusion?

    Cevap

    Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.

  165. Kart 165

    Soru

    What do 0 = 0 and 0 = 5 mean after simplifying an equation?

    Cevap

    0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.

  166. Kart 166

    Soru

    What should you verify before comparing figures from different sources?

    Cevap

    Common units and denominators. Convert first, then compare the same quantity on the same basis.

  167. Kart 167

    Soru

    How do you interpret |x − a| < r when r is positive?

    Cevap

    x is within r units of a: a − r < x < a + r.

  168. Kart 168

    Soru

    What can a larger sample improve?

    Cevap

    Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.

  169. Kart 169

    Soru

    How should a cross-source recommendation be evaluated?

    Cevap

    Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.

  170. Kart 170

    Soru

    If a worker finishes one job in t hours, what is the worker's hourly rate?

    Cevap

    1/t of the job per hour.

  171. Kart 171

    Soru

    What can an average hide?

    Cevap

    The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.

  172. Kart 172

    Soru

    What should you confirm before submitting a Multi-Source Reasoning answer?

    Cevap

    That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.

  173. Kart 173

    Soru

    How do you find the amount of a pure component in a mixture?

    Cevap

    Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.

  174. Kart 174

    Soru

    What role does a concession usually play?

    Cevap

    It acknowledges a point that weighs against the conclusion, then answers that point or limits its relevance. Don't mistake the conceded claim for the argument's main conclusion.

  175. Kart 175

    Soru

    When can an apparent cross-source discrepancy be resolved?

    Cevap

    When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.

  176. Kart 176

    Soru

    What is the two-set overlap formula?

    Cevap

    In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.

  177. Kart 177

    Soru

    What should you identify first in Table Analysis?

    Cevap

    The row unit, column definitions, and any notes. This establishes what one record and each value represent.

  178. Kart 178

    Soru

    What is the fundamental counting principle?

    Cevap

    Multiply the choices at successive stages when each stage has a fixed number of available choices.

  179. Kart 179

    Soru

    Why distinguish relative change from absolute change?

    Cevap

    Relative change is the percentage change; absolute change is the amount added or lost. A 50% rise from 2 adds 1, while a 10% rise from 1,000 adds 100.

  180. Kart 180

    Soru

    How should a table filter be translated?

    Cevap

    Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.

  181. Kart 181

    Soru

    For equally likely outcomes, what is the basic probability formula?

    Cevap

    Favorable outcomes divided by total possible outcomes.

  182. Kart 182

    Soru

    What makes a proposed causal mechanism useful?

    Cevap

    It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.

  183. Kart 183

    Soru

    How do you find the median?

    Cevap

    Order the values and take the middle value; for an even count, average the two middle values.

  184. Kart 184

    Soru

    How should numeric values be sorted?

    Cevap

    By numerical value, not digit order. For example, 12 comes after 9 in ascending order.

  185. Kart 185

    Soru

    What is missed when evidence includes only successful cases?

    Cevap

    The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.

  186. Kart 186

    Soru

    Two machines have stated constant rates of 1/3 and 1/5 job per hour and operate simultaneously without interference. May their rates be added?

    Cevap

    Yes. The stated rates are constant and the machines do not interfere, so their combined rate is 1/3 + 1/5 = 8/15 job per hour.

  187. Kart 187

    Soru

    How should a table ratio be built when filters are involved?

    Cevap

    Derive the numerator and denominator separately from the question, then apply each filter only where it is relevant. Do not automatically filter both quantities or default to all rows.

  188. Kart 188

    Soru

    What quantity is conserved when two solutions are mixed without loss?

    Cevap

    The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.

  189. Kart 189

    Soru

    When may table rows be added directly?

    Cevap

    Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.

  190. Kart 190

    Soru

    What does n! mean for a positive integer n?

    Cevap

    The product of the positive integers from 1 through n.

  191. Kart 191

    Soru

    Where is the argument's logical gap?

    Cevap

    Between the evidence and the conclusion. State what must connect them without merely repeating either side.

  192. Kart 192

    Soru

    How do you find the number in neither of two sets?

    Cevap

    Subtract the number in the union from the total population.

  193. Kart 193

    Soru

    How should rates from table groups be combined?

    Cevap

    Divide the total numerator by the total denominator. Weight a group rate by its group size only when that size is the rate's denominator.

  194. Kart 194

    Soru

    What is wrong with moving from some cases to all cases?

    Cevap

    The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.

  195. Kart 195

    Soru

    When should you use a permutation?

    Cevap

    When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.

  196. Kart 196

    Soru

    Why does table granularity matter?

    Cevap

    A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.

  197. Kart 197

    Soru

    How do you find the probability that an event does not occur?

    Cevap

    1 − P(event). This is often the quickest route for “at least one” questions.

  198. Kart 198

    Soru

    Why does a comparable control group help test causation?

    Cevap

    It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.

  199. Kart 199

    Soru

    How should missing table entries be treated?

    Cevap

    As unknown unless the notes define another meaning. Exclude or include them only as the question directs.

  200. Kart 200

    Soru

    What is the mode of a data set?

    Cevap

    A mode is any value with the greatest frequency. Under the no-mode convention, there is no mode only when at least two distinct values all have equal frequency.

  201. Kart 201

    Soru

    What makes a table comparison valid?

    Cevap

    The values must have compatible measures, units, periods, populations, and definitions. Normalize only validly convertible differences; reject differences in population, period, or definition that cannot be reconciled.

  202. Kart 202

    Soru

    What should you check when a prediction extends a past pattern?

    Cevap

    Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.

  203. Kart 203

    Soru

    How should a drain or other undoing process enter a work-rate equation?

    Cevap

    As a negative rate. Add productive rates and subtract rates that reverse the work.

  204. Kart 204

    Soru

    How can you avoid losing your place while scanning a table?

    Cevap

    Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.

  205. Kart 205

    Soru

    Can evidence that an outcome is possible show it is likely?

    Cevap

    No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.

  206. Kart 206

    Soru

    What correction is needed when counting the union of three sets?

    Cevap

    Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.

  207. Kart 207

    Soru

    When does a filtered table support a decision?

    Cevap

    When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.

  208. Kart 208

    Soru

    When should you use a combination?

    Cevap

    When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].

  209. Kart 209

    Soru

    What must support a recommendation?

    Cevap

    A link from the proposed action to the stated goal. The argument also needs the action to be feasible and free of costs that defeat the goal.

  210. Kart 210

    Soru

    How do AND and OR change a table filter?

    Cevap

    AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.

  211. Kart 211

    Soru

    How do you find the probability that independent events both occur?

    Cevap

    Multiply their probabilities: P(A and B) = P(A) × P(B).

  212. Kart 212

    Soru

    What can make an alphabetical sort misleading?

    Cevap

    Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.

  213. Kart 213

    Soru

    What kind of fact most directly strengthens an argument?

    Cevap

    A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.

  214. Kart 214

    Soru

    What is the range of a data set?

    Cevap

    Maximum value minus minimum value.

  215. Kart 215

    Soru

    What should you check at a filter cutoff?

    Cevap

    Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.

  216. Kart 216

    Soru

    A train covers 150 miles in 3 hours at a constant rate. What is its rate?

    Cevap

    50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.

  217. Kart 217

    Soru

    What is the most direct way to weaken an argument?

    Cevap

    Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.

  218. Kart 218

    Soru

    What does a tie in the sorted column imply?

    Cevap

    The tied rows share rank on that measure. Their display order does not create a performance difference.

  219. Kart 219

    Soru

    How do you identify a useful evaluation question?

    Cevap

    Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.

  220. Kart 220

    Soru

    What should you identify first in Graphics Interpretation?

    Cevap

    The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.

  221. Kart 221

    Soru

    How do repeated identical items affect arrangement counts?

    Cevap

    For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.

  222. Kart 222

    Soru

    What should you read before estimating a plotted value?

    Cevap

    Both axis labels, units, and category order. Position has meaning only after the axes are understood.

  223. Kart 223

    Soru

    How do you test whether a statement is a necessary assumption?

    Cevap

    Negate it. If that negation seriously damages the argument, the original statement was necessary.

  224. Kart 224

    Soru

    How do you find the probability that one of two mutually exclusive events occurs?

    Cevap

    Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.

  225. Kart 225

    Soru

    What should you verify in a chart legend?

    Cevap

    Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.

  226. Kart 226

    Soru

    What does standard deviation measure?

    Cevap

    How spread out values are around the mean. Greater dispersion means a larger standard deviation.

  227. Kart 227

    Soru

    What standard should an inference meet?

    Cevap

    It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.

  228. Kart 228

    Soru

    What does a segment’s share depend on?

    Cevap

    The correct whole. A category’s share of one region may differ from its share of the full dataset.

  229. Kart 229

    Soru

    For motion along the same line, when do you add or subtract two speeds to get relative speed?

    Cevap

    Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.

  230. Kart 230

    Soru

    What must a paradox explanation accomplish?

    Cevap

    Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.

  231. Kart 231

    Soru

    How is a segment in a stacked bar measured?

    Cevap

    Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.

  232. Kart 232

    Soru

    Eight students average 70 and twelve students average 80. What is the combined mean?

    Cevap

    1. The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
  233. Kart 233

    Soru

    What is the difference between a graph’s level and its rate of change?

    Cevap

    Level is the plotted value; rate of change is the slope. A high line can still be falling.

  234. Kart 234

    Soru

    How should you describe a statement's role in an argument?

    Cevap

    Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.

  235. Kart 235

    Soru

    What is P(A given B)?

    Cevap

    P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.

  236. Kart 236

    Soru

    How should slope be compared across a graph?

    Cevap

    Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.

  237. Kart 237

    Soru

    A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?

    Cevap

    No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.

  238. Kart 238

    Soru

    What should you identify first when evaluating a plan?

    Cevap

    The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.

  239. Kart 239

    Soru

    What does a trend in a scatterplot establish?

    Cevap

    An association in the displayed data. It does not by itself establish causation or predict every individual point.

  240. Kart 240

    Soru

    How can you strengthen a causal explanation?

    Cevap

    Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.

  241. Kart 241

    Soru

    How can an outlier affect a graphical trend?

    Cevap

    It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.

  242. Kart 242

    Soru

    Why do probabilities usually change when sampling without replacement?

    Cevap

    The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.

  243. Kart 243

    Soru

    One value in an n-value set increases by d. How does the mean change?

    Cevap

    It increases by d/n because the total rises by d while the count stays fixed.

  244. Kart 244

    Soru

    When does a counterexample weaken a claim?

    Cevap

    When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.

  245. Kart 245

    Soru

    What is the parity of the sum of two odd integers?

    Cevap

    Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.

  246. Kart 246

    Soru

    What can an aggregate graph hide?

    Cevap

    Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.

  247. Kart 247

    Soru

    When is interpolation reasonable on a graph?

    Cevap

    When the graph implies continuity between nearby points. Do not interpolate across separate categories.

  248. Kart 248

    Soru

    What makes information relevant to evaluating an argument?

    Cevap

    It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.

  249. Kart 249

    Soru

    How precise should a value read from a graph be?

    Cevap

    Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.

  250. Kart 250

    Soru

    Must a necessary assumption prove the conclusion?

    Cevap

    No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.

  251. Kart 251

    Soru

    How do you multiply positive numbers written in scientific notation?

    Cevap

    Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.

  252. Kart 252

    Soru

    How should a graph-based decision be made?

    Cevap

    Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.

  253. Kart 253

    Soru

    When is backsolving from answer choices especially useful?

    Cevap

    When the choices are concrete values and direct algebra is slower than testing them in the original conditions.

  254. Kart 254

    Soru

    How can axis scale distort a visual impression?

    Cevap

    Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.

  255. Kart 255

    Soru

    When should you combine two statements for an inference?

    Cevap

    When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.

  256. Kart 256

    Soru

    When is a product of integers odd?

    Cevap

    Only when every factor is odd. One even factor makes the entire product even.

  257. Kart 257

    Soru

    What often resolves two apparently conflicting results?

    Cevap

    A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.

  258. Kart 258

    Soru

    How should equal distances on a logarithmic axis be interpreted?

    Cevap

    As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.

  259. Kart 259

    Soru

    Why start with a middle answer choice when backsolving ordered options?

    Cevap

    Its result often eliminates half the choices at once when the relationship is monotonic.

  260. Kart 260

    Soru

    What makes a Two-Part Analysis response complete?

    Cevap

    Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.

  261. Kart 261

    Soru

    What is an analogy doing when it supports a claim?

    Cevap

    It argues that because two cases share relevant features, a result or principle from one likely applies to the other.

  262. Kart 262

    Soru

    How do you represent three consecutive odd integers?

    Cevap

    n, n + 2, and n + 4, where n is an odd integer.

  263. Kart 263

    Soru

    What should you identify before solving Two-Part Analysis?

    Cevap

    The role of each column. One may ask for a condition while the other asks for a consequence or decision.

  264. Kart 264

    Soru

    What values should you test first in a claim about an unspecified number?

    Cevap

    Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.

  265. Kart 265

    Soru

    How can an unchanged bottleneck defeat a plan?

    Cevap

    Improving a nonlimiting step won't improve the final outcome if another constraint still controls it. Faster ordering doesn't help when production is already full.

  266. Kart 266

    Soru

    How does the shared stem affect the two parts?

    Cevap

    Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.

  267. Kart 267

    Soru

    How do you count the positive divisors of an integer greater than 1 from its prime factorization?

    Cevap

    Add 1 to each prime exponent, then multiply those results.

  268. Kart 268

    Soru

    In Two-Part Analysis, must the two selected entries be the same?

    Cevap

    In the current format, the two selected entries may be the same or different. A linkage in the stem determines whether you must reason through them jointly, not whether their values match.

  269. Kart 269

    Soru

    What makes evidence for a general claim strong?

    Cevap

    It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.

  270. Kart 270

    Soru

    How do you factor a difference of squares?

    Cevap

    Use x² − y² = (x − y)(x + y).

  271. Kart 271

    Soru

    When should the two Two-Part Analysis selections be solved together?

    Cevap

    When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.

  272. Kart 272

    Soru

    How can one counterexample evaluate a universal claim?

    Cevap

    One valid counterexample disproves a claim that is supposed to hold for every allowed value.

  273. Kart 273

    Soru

    How does an alternative explanation weaken a conclusion?

    Cevap

    It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.

  274. Kart 274

    Soru

    In Two-Part Analysis, how can one column help solve the other?

    Cevap

    A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.

  275. Kart 275

    Soru

    How do you test whether x² + bx + c factors into integer binomials?

    Cevap

    Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).

  276. Kart 276

    Soru

    Which unknown should you evaluate first in a plan argument?

    Cevap

    A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.

  277. Kart 277

    Soru

    How should a trade-off between two measures be evaluated?

    Cevap

    Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.

  278. Kart 278

    Soru

    How can estimation screen answer choices before exact calculation?

    Cevap

    Approximate the expression's magnitude, then eliminate choices that are far too large or too small.

  279. Kart 279

    Soru

    In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?

    Cevap

    Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.

  280. Kart 280

    Soru

    What does a defensive assumption do?

    Cevap

    It rules out a threat that would break the argument. For example, a revenue plan may assume that its added costs won't exceed the new revenue.

  281. Kart 281

    Soru

    What restriction applies when a variable appears in a denominator?

    Cevap

    Exclude every value that makes the denominator zero.

  282. Kart 282

    Soru

    How does an objective differ from a constraint?

    Cevap

    A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.

  283. Kart 283

    Soru

    Which quick checks catch many Quant answer errors?

    Cevap

    Check the sign, units, allowed range, and rough size against the question's conditions.

  284. Kart 284

    Soru

    What inference is safe from a statement about most members?

    Cevap

    More than half have the stated trait. You can't infer that all do, that any particular member does, or that most have another trait.

  285. Kart 285

    Soru

    How should a two-part threshold rule be handled?

    Cevap

    Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.

  286. Kart 286

    Soru

    Where can one negative sign appear in a fraction without changing its value?

    Cevap

    Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.

  287. Kart 287

    Soru

    How does an argument choose between competing explanations?

    Cevap

    It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.

  288. Kart 288

    Soru

    What is an efficient way to handle two linked algebraic targets?

    Cevap

    Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.

  289. Kart 289

    Soru

    How do you solve x² = c over the real numbers?

    Cevap

    If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.

  290. Kart 290

    Soru

    What should you check when two selected quantities form a ratio?

    Cevap

    Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.

  291. Kart 291

    Soru

    How does a positive proper fraction compare with 1?

    Cevap

    It is less than 1 because its numerator is smaller than its denominator.

  292. Kart 292

    Soru

    Which side effects matter when evaluating a plan?

    Cevap

    Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.

  293. Kart 293

    Soru

    How should a two-part logical claim be tested?

    Cevap

    Separate the condition from the conclusion, then test whether each selected statement performs the requested role.

  294. Kart 294

    Soru

    What is the solution pattern for |x| = a over the real numbers?

    Cevap

    If a > 0, x = ±a; if a = 0, x = 0; if a < 0, there is no real solution.

  295. Kart 295

    Soru

    What unit check belongs in a two-part quantitative answer?

    Cevap

    Confirm that each selection has the unit requested by its column. Linked values may require different conversions.

  296. Kart 296

    Soru

    Why does user response matter to a plan?

    Cevap

    The plan may depend on people adopting, following, or not avoiding it. Availability alone doesn't guarantee the needed behavior.

  297. Kart 297

    Soru

    A response rate rises from 40% to 50%. What are the percentage-point change and the relative percent increase?

    Cevap

    The increase is 10 percentage points and 25% relative to the original rate: (50 − 40) ÷ 40 = 0.25.

  298. Kart 298

    Soru

    What is the final check for Two-Part Analysis?

    Cevap

    Read each column prompt with its chosen entry, then verify that the pair is jointly consistent with the stem.

  299. Kart 299

    Soru

    For real x and y, what two linear cases are equivalent to x² = y²?

    Cevap

    x = y or x = −y.

  300. Kart 300

    Soru

    How should benefits and costs be compared in a plan argument?

    Cevap

    By their net effect on the stated goal. A plan can create the intended benefit but still fail if its relevant costs are larger.
