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.

اس ڈیک کے کارڈز
کارڈ 1
سوال
Which numerator-and-denominator operation creates an equivalent fraction?
جواب
Multiply or divide the numerator and denominator by the same nonzero number. The fraction's value stays unchanged.
کارڈ 2
سوال
What does data sufficiency ask you to determine?
جواب
Whether the information guarantees one answer. You usually don’t need to calculate that answer.
کارڈ 3
سوال
How do you form a passage's main idea?
جواب
Combine the passage's central topic with its main claim about that topic. The answer should cover the whole passage at the right level.
کارڈ 4
سوال
What does multiplying a decimal by 10ⁿ do when n is a positive integer?
جواب
It moves the decimal point n places to the right. Dividing by 10ⁿ moves it n places left.
کارڈ 5
سوال
What makes information sufficient for a value question?
جواب
It forces exactly one value for the target. Different values that satisfy all conditions make it insufficient.
کارڈ 6
سوال
How do you identify the passage's primary purpose?
جواب
Name what the author is doing with the topic: explaining, comparing, challenging, defending, or proposing. Keep content and action together.
کارڈ 7
سوال
How do you find p percent of a quantity q?
جواب
Compute (p/100) × q. Translate “of” as multiplication.
کارڈ 8
سوال
How can two valid cases prove insufficiency?
جواب
Make the cases produce different answers to the question. One clean counterexample pair is enough.
کارڈ 9
سوال
How do you determine a paragraph's role?
جواب
Connect the paragraph to what comes before and after it. Decide whether it introduces, supports, qualifies, contrasts, applies, or concludes the larger discussion.
کارڈ 10
سوال
A total of 45 is split in the ratio 2:3. What are the two parts?
جواب
18 and 27. The five ratio units are worth 45 ÷ 5 = 9 each.
کارڈ 11
سوال
Why can an integer restriction change sufficiency?
جواب
It removes noninteger possibilities. A range containing many real numbers may contain only one integer.
کارڈ 12
سوال
When is a product of signed factors negative?
جواب
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.
کارڈ 13
سوال
How should two data-sufficiency statements be tested initially?
جواب
Test each statement independently against the stem. Do not carry information from one statement into the other.
کارڈ 14
سوال
What makes an integer greater than 1 prime?
جواب
It has exactly two positive divisors: 1 and itself.
کارڈ 15
سوال
What should you do first on a detail question?
جواب
Return to the relevant lines and read their local context. Memory tends to preserve the topic while blurring qualifications.
کارڈ 16
سوال
What is the divisibility rule for 2?
جواب
The last digit must be even: 0, 2, 4, 6, or 8.
کارڈ 17
سوال
How do you test whether a fact is relevant?
جواب
Connect it to the requested target. A true fact that does not narrow the target adds no decision value.
کارڈ 18
سوال
How far may a reading inference go beyond the text?
جواب
Only as far as the text strongly supports. Prefer the smallest justified step and reject claims needing outside knowledge.
کارڈ 19
سوال
Why is prime factorization useful in GMAT arithmetic?
جواب
It exposes divisibility, factors, greatest common factors, least common multiples, and perfect powers.
کارڈ 20
سوال
What must happen before quantities with different units are combined?
جواب
First confirm that their dimensions are compatible, then convert them to a common unit. Keep the unit attached through the calculation to catch mismatches.
کارڈ 21
سوال
How do you apply a passage principle to a new case?
جواب
Extract the principle's required conditions, then test whether the new case has them. Surface similarity isn't enough.
کارڈ 22
سوال
Which relationship connects distance, rate, and time?
جواب
Distance = rate × time. Rearrange only after the units are compatible.
کارڈ 23
سوال
How do you find a least common multiple from prime factorizations?
جواب
Take every prime that appears, using the largest exponent present.
کارڈ 24
سوال
How do you multiply powers with the same base?
جواب
Add the exponents: aᵐ × aⁿ = aᵐ⁺ⁿ.
کارڈ 25
سوال
How is a weighted average computed?
جواب
Divide the total weighted value by the total weight. For groups, use group size as the weight unless another weight is given.
کارڈ 26
سوال
What should a quick passage map record?
جواب
Each paragraph's role and major viewpoint, plus the passage's overall direction. Record structure, not a sentence-by-sentence summary.
کارڈ 27
سوال
What does the principal square root symbol √x return?
جواب
For real x ≥ 0, it is the nonnegative number whose square is x. For example, √9 = 3, not ±3.
کارڈ 28
سوال
When can bounds replace exact arithmetic?
جواب
When the bounds separate the viable decisions. Stop once every value in the interval leads to the same choice.
کارڈ 29
سوال
How do you keep viewpoints separate?
جواب
Attach each claim to its speaker: author, critic, researcher, or group. Track agreement, disagreement, and any later qualification.
کارڈ 30
سوال
How do “sum,” “product,” and “quotient” translate into algebra?
جواب
They mean addition, multiplication, and division, respectively.
کارڈ 31
سوال
How do you reduce a fraction to lowest terms?
جواب
Divide the numerator and denominator by their greatest common factor.
کارڈ 32
سوال
What evidence should determine the author's tone?
جواب
Evaluative words, qualifications, and the treatment of competing views. Topic alone doesn't establish approval, concern, or skepticism.
کارڈ 33
سوال
When should rounding usually occur?
جواب
At the end, unless estimation already settles the decision. Early rounding can move a result across a cutoff.
کارڈ 34
سوال
How do you convert a terminating decimal to a fraction?
جواب
Write the digits over the matching power of 10, then reduce. For example, 0.375 = 375/1000 = 3/8.
کارڈ 35
سوال
When should you stop calculating in a sufficiency problem?
جواب
As soon as uniqueness is proved or disproved. More arithmetic cannot change the sufficiency decision.
کارڈ 36
سوال
How do you spot an out-of-scope answer?
جواب
It introduces a person, period, cause, or consequence the passage doesn't address. Being reasonable doesn't make it textually supported.
کارڈ 37
سوال
What is the percent-change formula?
جواب
For original > 0, percent change = (new − original) / original × 100%. Percent change from zero is undefined; negative baselines require context-specific interpretation.
کارڈ 38
سوال
What makes information sufficient for a yes-or-no question?
جواب
It forces the same yes-or-no answer in every valid case. The underlying value may still vary.
کارڈ 39
سوال
What preserves a ratio when its quantities are scaled?
جواب
Multiplying or dividing both terms by the same nonzero factor preserves the ratio.
کارڈ 40
سوال
How do you reject a main-idea answer with the wrong scope?
جواب
Compare it with the whole passage. A detail-only answer is too narrow; a claim extending beyond the passage is too broad.
کارڈ 41
سوال
Why should you track whether a variable is positive, negative, or zero?
جواب
Sign controls valid cases and operations. Squaring can hide sign, and division requires a nonzero denominator.
کارڈ 42
سوال
How do you simplify subtraction of a negative number?
جواب
Change it to addition: a − (−b) = a + b.
کارڈ 43
سوال
Whose purpose matters in a primary-purpose question?
جواب
The passage author's purpose. A theory or researcher may be described at length without representing what the author ultimately wants to do.
کارڈ 44
سوال
When is the on-screen calculator most useful?
جواب
For tedious arithmetic after the setup is clear. It does not replace choosing the right relationship or denominator.
کارڈ 45
سوال
In Data Sufficiency, what stem information applies when testing either statement?
جواب
Everything in the question stem. Stem facts remain active for each statement and for the combination.
کارڈ 46
سوال
What is the divisibility rule for 3?
جواب
The sum of the digits must be divisible by 3.
کارڈ 47
سوال
What does a transition paragraph often do?
جواب
It closes one line of thought and sets up the next. Its role depends on both sides, not only on its first sentence.
کارڈ 48
سوال
When is a proxy measure useful?
جواب
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.
کارڈ 49
سوال
How do you find a greatest common factor from prime factorizations?
جواب
Take each shared prime to the smaller exponent.
کارڈ 50
سوال
What is the arithmetic mean?
جواب
The sum of the values divided by the number of values.
کارڈ 51
سوال
What units should a rate have?
جواب
One quantity per another, such as kilometers per hour. The denominator tells you what the rate is measured against.
کارڈ 52
سوال
How do you divide powers with the same nonzero base?
جواب
Subtract the exponents: aᵐ ÷ aⁿ = aᵐ⁻ⁿ.
کارڈ 53
سوال
What makes a paraphrase faithful to a passage detail?
جواب
It preserves the original meaning, scope, and certainty in different words. Shared keywords alone don't make it accurate.
کارڈ 54
سوال
How do you recover a total from an average?
جواب
Total = average × number of values.
کارڈ 55
سوال
How do you choose between two plausible reading inferences?
جواب
Choose the one with the tighter textual chain and fewer assumptions. Plausibility in the real world is secondary.
کارڈ 56
سوال
What quick check can catch a calculator-entry error?
جواب
Estimate the order of magnitude and direction first. An exact result far outside that range deserves another look.
کارڈ 57
سوال
How do you simplify a square root with a perfect-square factor?
جواب
Factor out the perfect square. For example, √72 = √(36 × 2) = 6√2.
کارڈ 58
سوال
What makes a new example parallel to one in the passage?
جواب
The same logical relationship. Match cause, contrast, exception, or function rather than shared subject matter.
کارڈ 59
سوال
When can work rates be added?
جواب
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.
کارڈ 60
سوال
What is the denominator in a percent comparison?
جواب
The stated reference value. “A as a percent of B” means A divided by B, then multiplied by 100.
کارڈ 61
سوال
How do you translate “5 less than x”?
جواب
x − 5. The phrase “less than” reverses the spoken order.
کارڈ 62
سوال
In Data Sufficiency, what should you check before testing values?
جواب
The full domain. Honor stated restrictions and implicit ones such as positive lengths or nonzero divisors before judging sufficiency.
کارڈ 63
سوال
How do you add fractions with different denominators?
جواب
Rewrite them with a common denominator, then add the numerators. For example, 2/3 + 1/4 = 8/12 + 3/12 = 11/12.
کارڈ 64
سوال
How do you distinguish description from argument in a passage?
جواب
Description presents what happened or what a view says; argument gives reasons to accept, reject, or revise a claim.
کارڈ 65
سوال
How should you compare decimals with different lengths?
جواب
Append trailing zeros and compare place by place. For example, compare 0.47 with 0.4700, which are equal.
کارڈ 66
سوال
How should combined statements be evaluated?
جواب
Intersect their constraints with the stem. The combination is sufficient only if every remaining case gives one answer.
کارڈ 67
سوال
How do you find common ground between two viewpoints?
جواب
Look for the narrow claim both accept, even if they disagree about its cause, importance, or implications.
کارڈ 68
سوال
How do you solve a proportion such as a/b = c/d?
جواب
Cross-multiply to get ad = bc, provided b and d are nonzero.
کارڈ 69
سوال
How is average speed computed?
جواب
Total distance divided by total time. It is not usually the simple mean of the segment speeds.
کارڈ 70
سوال
What does |x| represent?
جواب
The nonnegative distance from x to 0 on the number line.
کارڈ 71
سوال
Why are strongly emotional tone descriptions often wrong?
جواب
They overstate measured academic prose. Match the answer's intensity to the author's actual language.
کارڈ 72
سوال
What is the divisibility rule for 4?
جواب
The number formed by the last two digits must be divisible by 4.
کارڈ 73
سوال
Can the ordinary percent-change formula be applied directly when the original value is zero or negative?
جواب
No. The ordinary GMAT rule assumes original > 0. Change from zero is undefined, and a negative baseline requires context-specific interpretation.
کارڈ 74
سوال
Why can a true statement still be a wrong answer?
جواب
It may not answer the question asked. Check the task—main idea, detail, inference, role, or purpose—before checking truth.
کارڈ 75
سوال
When must a weighted average lie between its component values?
جواب
When every weight is nonnegative and the total weight is positive. The average then lies between the smallest and largest component values.
کارڈ 76
سوال
How do you express an integer n divided by d with remainder r?
جواب
n = dq + r, where q is an integer and 0 ≤ r < d for positive d.
کارڈ 77
سوال
What does an inequality usually provide?
جواب
A range, not a unique value. It can still be sufficient if the question asks whether a threshold is crossed.
کارڈ 78
سوال
How should you handle an EXCEPT detail prompt?
جواب
Verify four statements against the passage and select the one that isn't supported. Keep the reversed task visible while checking each choice.
کارڈ 79
سوال
How should you set up a unit conversion?
جواب
Multiply by a conversion factor equal to 1, placing units so the unwanted unit cancels.
کارڈ 80
سوال
Can two individually insufficient statements remain insufficient together?
جواب
Yes. They may repeat the same limitation or still leave multiple valid answers.
کارڈ 81
سوال
For a positive base, how do you simplify a power raised to another power?
جواب
Multiply the exponents: (aᵐ)ⁿ = a^(mn).
کارڈ 82
سوال
When can you infer that an author accepts a claim?
جواب
When the author endorses it directly or relies on it without distancing language. Merely reporting another person's view isn't endorsement.
کارڈ 83
سوال
How should successive percentage changes be combined?
جواب
Multiply their factors. A 10% rise followed by a 10% fall gives 1.10 × 0.90 = 0.99, a 1% net fall.
کارڈ 84
سوال
What are compatible numbers in estimation?
جواب
Nearby numbers chosen to make mental arithmetic easy, such as 203 ÷ 9.9 ≈ 200 ÷ 10 = 20.
کارڈ 85
سوال
Which constraints are easy to overlook in a word problem?
جواب
Countability, positivity, distinctness, and capacity limits. Translate each noun and rule into a usable constraint.
کارڈ 86
سوال
How do you state the exact disagreement between two viewpoints?
جواب
Identify one claim that one side accepts and the other rejects. Don't substitute a topic that only one side discusses.
کارڈ 87
سوال
How do you represent three consecutive integers?
جواب
n, n + 1, and n + 2 for an integer n.
کارڈ 88
سوال
How do percentage points differ from percent change?
جواب
Percentage points are the direct difference between percentages. Moving from 20% to 25% is 5 points and a 25% relative increase.
کارڈ 89
سوال
What is a reversed-relationship trap?
جواب
It swaps cause and effect, support and conclusion, or the positions of two viewpoints while reusing familiar passage language.
کارڈ 90
سوال
How do you multiply two fractions?
جواب
Multiply numerator by numerator and denominator by denominator, canceling common factors when convenient.
کارڈ 91
سوال
How do direct and inverse proportion differ?
جواب
Direct:
y = kx; inverse:y = k/xforx ≠ 0.کارڈ 92
سوال
How do you recover an original value after a percentage increase?
جواب
Divide the new value by the growth factor. After a 20% increase, original = new ÷ 1.20.
کارڈ 93
سوال
When should absolute wording raise suspicion?
جواب
When the passage is qualified. Words such as always, never, entirely, and impossible require equally strong textual support.
کارڈ 94
سوال
What should you identify first in Data Sufficiency?
جواب
The exact target and answer type. Decide whether the stem asks for a value, a comparison, or a yes-or-no result.
کارڈ 95
سوال
What ending makes an integer divisible by 5 or by 10?
جواب
A last digit of 0 or 5 gives divisibility by 5; a last digit of 0 gives divisibility by 10.
کارڈ 96
سوال
How should a Data Sufficiency condition be handled?
جواب
Translate it into a precise constraint before testing sufficiency. Keep it separate from the conclusion you want.
کارڈ 97
سوال
How do you reject a half-right answer?
جواب
Test every part of it. One accurate clause can't rescue a second clause that distorts the passage or exceeds its scope.
کارڈ 98
سوال
When you convert a positive measurement to a smaller linear unit, what happens to its numerical value?
جواب
It increases. Multiply by the number of smaller units in one larger unit.
کارڈ 99
سوال
DS example: Is x > 5? Statement: x > 3. Is the statement sufficient?
جواب
No. Both x = 4 and x = 6 satisfy the statement, but they answer the stem differently.
کارڈ 100
سوال
What is a⁰ when a is nonzero?
جواب
- The nonzero-base condition matters because 0⁰ is not assigned this rule.
کارڈ 101
سوال
Which claim is the argument trying to establish?
جواب
The main conclusion. Find the claim supported by the other statements, then check that it answers the argument's central issue.
کارڈ 102
سوال
When should the two statements be combined?
جواب
When neither statement is sufficient alone. Use both constraints at once and test the remaining possibilities.
کارڈ 103
سوال
A positive number rounds to 8.2 to the nearest tenth. What interval contains it?
جواب
8.15 ≤ x < 8.25. The lower endpoint rounds up to 8.2; the upper endpoint rounds to 8.3.
کارڈ 104
سوال
What should you check when the conclusion changes populations?
جواب
Whether the evidence applies to the new population. Results from volunteers, specialists, or one age group may not transfer to everyone.
کارڈ 105
سوال
How should test values be chosen in Data Sufficiency?
جواب
Choose valid values that probe boundaries, signs, and distinct outcomes. Random easy values can miss the deciding case.
کارڈ 106
سوال
How do you translate “A is 30% more than B”?
جواب
A = 1.30B. The percentage is based on B.
کارڈ 107
سوال
When can one equation involving two variables be sufficient for a target?
جواب
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.
کارڈ 108
سوال
What does a correlation establish by itself?
جواب
Only that two things vary together. It doesn't establish which one causes the other or whether a third factor causes both.
کارڈ 109
سوال
How do you divide by a nonzero fraction?
جواب
Multiply by its reciprocal. For example, 3/5 ÷ 2/7 = 3/5 × 7/2.
کارڈ 110
سوال
Why is a ratio often insufficient for an absolute value?
جواب
A ratio fixes relative size but usually leaves the scale free. Many proportional pairs can share the same ratio.
کارڈ 111
سوال
What is the divisibility rule for 9?
جواب
The sum of the digits must be divisible by 9.
کارڈ 112
سوال
What matters most when applying a sample result to a population?
جواب
Representativeness. The sample must resemble the target population on traits that could affect the result.
کارڈ 113
سوال
What should you check after solving a squared equation?
جواب
Check every allowed root. If positive and negative roots produce different target answers, the information is insufficient.
کارڈ 114
سوال
What does a negative exponent mean?
جواب
It takes the reciprocal: a⁻ⁿ = 1/aⁿ for nonzero a.
کارڈ 115
سوال
Which baseline makes a comparison informative?
جواب
The baseline relevant to the claim. Compare the outcome with what would otherwise have happened, not merely with an unrelated earlier figure.
کارڈ 116
سوال
What risk appears when an equation factors into multiple branches?
جواب
Each branch may create valid cases. Test all branches against the stem before deciding sufficiency.
کارڈ 117
سوال
How can you compare two positive fractions quickly?
جواب
Compare their cross-products. For a/b and c/d with positive denominators, compare ad with bc.
کارڈ 118
سوال
What may be assumed from a Data Sufficiency diagram?
جواب
Only marked or stated facts. Do not infer scale, equality, perpendicularity, or midpoint status from appearance.
کارڈ 119
سوال
What multiplier represents a p percent increase or decrease?
جواب
Use 1 + p/100 for an increase and 1 − p/100 for a decrease.
کارڈ 120
سوال
Which statements count as evidence?
جواب
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.
کارڈ 121
سوال
Can a mean determine an individual observation?
جواب
Not by itself. A mean fixes the total, but different sets can have that total unless more constraints apply.
کارڈ 122
سوال
What weakens a move from past evidence to a present claim?
جواب
A relevant change over time. New technology, prices, rules, or behavior can make the earlier evidence a poor guide.
کارڈ 123
سوال
A value becomes 96 after a 20% increase. What was the original value?
جواب
- Divide the final value by the growth multiplier: 96 ÷ 1.2 = 80.
کارڈ 124
سوال
How do extreme valid cases help in Data Sufficiency?
جواب
They expose whether the target can change. Test the smallest, largest, or boundary cases allowed by the conditions.
کارڈ 125
سوال
How do you test for reverse causation?
جواب
Ask whether the alleged effect could instead cause the alleged cause. Productive teams may meet more because they are productive, not the reverse.
کارڈ 126
سوال
Must a sufficient statement make every variable unique?
جواب
No. It only needs to make the requested target unique, even if other variables remain undetermined.
کارڈ 127
سوال
A price rises 20% and then falls 20%. Does it return to its original value?
جواب
No. The multipliers give 1.20 × 0.80 = 0.96, so the final price is 4% below the original.
کارڈ 128
سوال
Why can a voluntary survey be biased?
جواب
People who choose to respond may differ from those who don't. Strong opinions or extra interest can distort the sample.
کارڈ 129
سوال
How do you expand a(b + c)?
جواب
ab + ac. The outside factor multiplies every term inside the parentheses.
کارڈ 130
سوال
What should the final Data Sufficiency decision describe?
جواب
Which information set guarantees an answer. It should not report the target’s numerical value.
کارڈ 131
سوال
What is the goal when solving a linear equation?
جواب
Isolate the variable by applying equivalent operations to both sides.
کارڈ 132
سوال
DS example: Is integer n even? Statement: n = 7. Is the statement sufficient?
جواب
Yes. It guarantees one answer—no. A statement can be sufficient even when that answer is negative.
کارڈ 133
سوال
When must an inequality sign reverse?
جواب
When both sides are multiplied or divided by a negative number.
کارڈ 134
سوال
What must be checked before comparing two groups?
جواب
Whether they differ in other relevant ways. Age, experience, starting level, or incentives may explain the outcome instead.
کارڈ 135
سوال
When is substitution preferable to elimination in a two-equation system?
جواب
Use substitution when one variable is already isolated or easy to isolate; use elimination when coefficients cancel easily.
کارڈ 136
سوال
What should you build before analyzing Multi-Source Reasoning material?
جواب
A quick source map. Note what each tab or document contains, who produced it, and the relevant date or scope.
کارڈ 137
سوال
How do you separate background from evidence?
جواب
Ask whether the statement supports a claim. Background sets context; evidence does logical work in moving the argument toward a conclusion.
کارڈ 138
سوال
Which algebraic terms can be combined?
جواب
Terms with the same variable part and exponents. For example, 3x² and −5x² combine, but 3x² and 3x do not.
کارڈ 139
سوال
When should you read the Multi-Source Reasoning question?
جواب
Before a deep read of every source. The question tells you which details deserve attention.
کارڈ 140
سوال
What is a reliable first step for an equation containing several fractions?
جواب
Multiply every term by the least common denominator, then solve the simpler equation.
کارڈ 141
سوال
Why does source provenance matter?
جواب
It defines what a claim can support. An internal forecast and an audited result do not carry the same evidentiary weight.
کارڈ 142
سوال
What should you test when evidence comes from a different setting?
جواب
Whether the settings differ in a way that affects the result. A finding from one market, school, or climate may not carry over unchanged.
کارڈ 143
سوال
What does an “and” compound inequality require?
جواب
The overlap of both solution sets. A value must satisfy both conditions.
کارڈ 144
سوال
What should you compare before combining claims from two sources?
جواب
Their population, period, units, and definitions. Matching labels can hide different scopes.
کارڈ 145
سوال
How can a third factor undermine a causal claim?
جواب
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.
کارڈ 146
سوال
What do one, zero, or infinitely many solutions mean for two linear equations in two variables?
جواب
The lines intersect once, are parallel and distinct, or are the same line, respectively.
کارڈ 147
سوال
How should records from separate sources be linked?
جواب
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.
کارڈ 148
سوال
How do you factor 6x + 9?
جواب
3(2x + 3). Pull out the greatest common factor.
کارڈ 149
سوال
When does nonresponse threaten a survey result?
جواب
When nonrespondents may answer differently from respondents. A high response count doesn't fix a systematic missing group.
کارڈ 150
سوال
What is the first step when two sources seem inconsistent?
جواب
Compare definitions, dates, units, and aggregation levels. Many apparent conflicts come from mismatched frames.

سوال
When can you use the zero-product property?
جواب
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
کارڈ 152
سوال
How does an inference differ from a stated fact?
جواب
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
کارڈ 153
سوال
Does a higher percentage by itself prove a higher count?
جواب
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
کارڈ 154
سوال
What does an “or” compound inequality require?
جواب
The union of the solution sets. A value may satisfy either condition or both.
کارڈ 155
سوال
What does a blank or omitted value establish?
جواب
Only that the value is not provided. It does not establish zero, no change, or failure.
کارڈ 156
سوال
How do you recognize an intermediate conclusion?
جواب
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
کارڈ 157
سوال
What should you do before writing equations for a two-quantity word problem?
جواب
Define each variable with its unit, then translate one independent relationship per equation.
کارڈ 158
سوال
Why should cross-source events be placed in time order?
جواب
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
کارڈ 159
سوال
When should candidate solutions be checked in the original equation?
جواب
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
کارڈ 160
سوال
How can switching from one measured outcome to another create a gap?
جواب
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
کارڈ 161
سوال
What makes a source relevant to a claim?
جواب
It supplies evidence for a required link in the claim. Related background alone is not enough.
کارڈ 162
سوال
How do you solve a factored polynomial inequality reliably?
جواب
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
کارڈ 163
سوال
Does happening first prove causation?
جواب
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
کارڈ 164
سوال
How can you spot an unsupported cross-source conclusion?
جواب
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
کارڈ 165
سوال
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
جواب
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
کارڈ 166
سوال
What should you verify before comparing figures from different sources?
جواب
Common units and denominators. Convert first, then compare the same quantity on the same basis.
کارڈ 167
سوال
How do you interpret |x − a| < r when r is positive?
جواب
x is within r units of a: a − r < x < a + r.
کارڈ 168
سوال
What can a larger sample improve?
جواب
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
کارڈ 169
سوال
How should a cross-source recommendation be evaluated?
جواب
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
کارڈ 170
سوال
If a worker finishes one job in t hours, what is the worker's hourly rate?
جواب
1/t of the job per hour.
کارڈ 171

What can an average hide?
جواب
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
کارڈ 172
سوال
What should you confirm before submitting a Multi-Source Reasoning answer?
جواب
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
کارڈ 173
سوال
How do you find the amount of a pure component in a mixture?
جواب
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
کارڈ 174
سوال
What role does a concession usually play?
جواب
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.
کارڈ 175
سوال
When can an apparent cross-source discrepancy be resolved?
جواب
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
کارڈ 176
سوال
What is the two-set overlap formula?
جواب
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
کارڈ 177
سوال
What should you identify first in Table Analysis?
جواب
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
کارڈ 178
سوال
What is the fundamental counting principle?
جواب
Multiply the choices at successive stages when each stage has a fixed number of available choices.
کارڈ 179
سوال
Why distinguish relative change from absolute change?
جواب
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.
کارڈ 180
سوال
How should a table filter be translated?
جواب
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
کارڈ 181

For equally likely outcomes, what is the basic probability formula?
جواب
Favorable outcomes divided by total possible outcomes.
کارڈ 182
سوال
What makes a proposed causal mechanism useful?
جواب
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
کارڈ 183
سوال
How do you find the median?
جواب
Order the values and take the middle value; for an even count, average the two middle values.
کارڈ 184
سوال
How should numeric values be sorted?
جواب
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
کارڈ 185
سوال
What is missed when evidence includes only successful cases?
جواب
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
کارڈ 186
سوال
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?
جواب
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.
کارڈ 187
سوال
How should a table ratio be built when filters are involved?
جواب
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.
کارڈ 188
سوال
What quantity is conserved when two solutions are mixed without loss?
جواب
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
کارڈ 189
سوال
When may table rows be added directly?
جواب
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
کارڈ 190

What does n! mean for a positive integer n?
جواب
The product of the positive integers from 1 through n.
کارڈ 191
سوال
Where is the argument's logical gap?
جواب
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
کارڈ 192
سوال
How do you find the number in neither of two sets?
جواب
Subtract the number in the union from the total population.
کارڈ 193
سوال
How should rates from table groups be combined?
جواب
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.
کارڈ 194
سوال
What is wrong with moving from some cases to all cases?
جواب
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
کارڈ 195
سوال
When should you use a permutation?
جواب
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
کارڈ 196
سوال
Why does table granularity matter?
جواب
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
کارڈ 197
سوال
How do you find the probability that an event does not occur?
جواب
1 − P(event). This is often the quickest route for “at least one” questions.
کارڈ 198
سوال
Why does a comparable control group help test causation?
جواب
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
کارڈ 199
سوال
How should missing table entries be treated?
جواب
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
کارڈ 200
سوال
What is the mode of a data set?
جواب
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.
کارڈ 201
سوال
What makes a table comparison valid?
جواب
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.
کارڈ 202
سوال
What should you check when a prediction extends a past pattern?
جواب
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
کارڈ 203
سوال
How should a drain or other undoing process enter a work-rate equation?
جواب
As a negative rate. Add productive rates and subtract rates that reverse the work.
کارڈ 204
سوال
How can you avoid losing your place while scanning a table?
جواب
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
کارڈ 205
سوال
Can evidence that an outcome is possible show it is likely?
جواب
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
کارڈ 206
سوال
What correction is needed when counting the union of three sets?
جواب
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
کارڈ 207
سوال
When does a filtered table support a decision?
جواب
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
کارڈ 208
سوال
When should you use a combination?
جواب
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
کارڈ 209
سوال
What must support a recommendation?
جواب
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.
کارڈ 210
سوال
How do AND and OR change a table filter?
جواب
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
کارڈ 211
سوال
How do you find the probability that independent events both occur?
جواب
Multiply their probabilities: P(A and B) = P(A) × P(B).
کارڈ 212
سوال
What can make an alphabetical sort misleading?
جواب
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
کارڈ 213
سوال
What kind of fact most directly strengthens an argument?
جواب
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
کارڈ 214
سوال
What is the range of a data set?
جواب
Maximum value minus minimum value.
کارڈ 215
سوال
What should you check at a filter cutoff?
جواب
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
کارڈ 216
سوال
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
جواب
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
کارڈ 217
سوال
What is the most direct way to weaken an argument?
جواب
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
کارڈ 218
سوال
What does a tie in the sorted column imply?
جواب
The tied rows share rank on that measure. Their display order does not create a performance difference.
کارڈ 219
سوال
How do you identify a useful evaluation question?
جواب
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
کارڈ 220
سوال
What should you identify first in Graphics Interpretation?
جواب
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
کارڈ 221
سوال
How do repeated identical items affect arrangement counts?
جواب
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
کارڈ 222
سوال
What should you read before estimating a plotted value?
جواب
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
کارڈ 223
سوال
How do you test whether a statement is a necessary assumption?
جواب
Negate it. If that negation seriously damages the argument, the original statement was necessary.
کارڈ 224
سوال
How do you find the probability that one of two mutually exclusive events occurs?
جواب
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
کارڈ 225
سوال
What should you verify in a chart legend?
جواب
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
کارڈ 226
سوال
What does standard deviation measure?
جواب
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
کارڈ 227
سوال
What standard should an inference meet?
جواب
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
کارڈ 228
سوال
What does a segment’s share depend on?
جواب
The correct whole. A category’s share of one region may differ from its share of the full dataset.
کارڈ 229
سوال
For motion along the same line, when do you add or subtract two speeds to get relative speed?
جواب
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
کارڈ 230
سوال
What must a paradox explanation accomplish?
جواب
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
کارڈ 231
سوال
How is a segment in a stacked bar measured?
جواب
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
کارڈ 232
سوال
Eight students average 70 and twelve students average 80. What is the combined mean?
جواب
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
کارڈ 233
سوال
What is the difference between a graph’s level and its rate of change?
جواب
Level is the plotted value; rate of change is the slope. A high line can still be falling.
کارڈ 234
سوال
How should you describe a statement's role in an argument?
جواب
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
کارڈ 235
سوال
What is P(A given B)?
جواب
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
کارڈ 236
سوال
How should slope be compared across a graph?
جواب
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
کارڈ 237
سوال
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
جواب
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
کارڈ 238
سوال
What should you identify first when evaluating a plan?
جواب
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
کارڈ 239
سوال
What does a trend in a scatterplot establish?
جواب
An association in the displayed data. It does not by itself establish causation or predict every individual point.
کارڈ 240
سوال
How can you strengthen a causal explanation?
جواب
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
کارڈ 241
سوال
How can an outlier affect a graphical trend?
جواب
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
کارڈ 242
سوال
Why do probabilities usually change when sampling without replacement?
جواب
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
کارڈ 243
سوال
One value in an n-value set increases by d. How does the mean change?
جواب
It increases by d/n because the total rises by d while the count stays fixed.
کارڈ 244
سوال
When does a counterexample weaken a claim?
جواب
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
کارڈ 245
سوال
What is the parity of the sum of two odd integers?
جواب
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
کارڈ 246
سوال
What can an aggregate graph hide?
جواب
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
کارڈ 247
سوال
When is interpolation reasonable on a graph?
جواب
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
کارڈ 248
سوال
What makes information relevant to evaluating an argument?
جواب
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
کارڈ 249
سوال
How precise should a value read from a graph be?
جواب
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
کارڈ 250
سوال
Must a necessary assumption prove the conclusion?
جواب
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
کارڈ 251
سوال
How do you multiply positive numbers written in scientific notation?
جواب
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
کارڈ 252

How should a graph-based decision be made?
جواب
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
کارڈ 253
سوال
When is backsolving from answer choices especially useful?
جواب
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
کارڈ 254
سوال
How can axis scale distort a visual impression?
جواب
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
کارڈ 255
سوال
When should you combine two statements for an inference?
جواب
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
کارڈ 256
سوال
When is a product of integers odd?
جواب
Only when every factor is odd. One even factor makes the entire product even.
کارڈ 257
سوال
What often resolves two apparently conflicting results?
جواب
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
کارڈ 258
سوال
How should equal distances on a logarithmic axis be interpreted?
جواب
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
کارڈ 259

Why start with a middle answer choice when backsolving ordered options?
جواب
Its result often eliminates half the choices at once when the relationship is monotonic.

What values should you test first in a claim about an unspecified number?
جواب
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
کارڈ 265
سوال
How can an unchanged bottleneck defeat a plan?
جواب
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.
کارڈ 266

How does the shared stem affect the two parts?
جواب
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
کارڈ 267

How do you count the positive divisors of an integer greater than 1 from its prime factorization?
جواب
Add 1 to each prime exponent, then multiply those results.
کارڈ 268
سوال
In Two-Part Analysis, must the two selected entries be the same?
جواب
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.
کارڈ 269
سوال
What makes evidence for a general claim strong?
جواب
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.

How do you factor a difference of squares?
جواب
Use x² − y² = (x − y)(x + y).
کارڈ 271
سوال
When should the two Two-Part Analysis selections be solved together?
جواب
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
کارڈ 272
سوال
How can one counterexample evaluate a universal claim?
جواب
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
کارڈ 273
سوال
How does an alternative explanation weaken a conclusion?
جواب
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
کارڈ 274

In Two-Part Analysis, how can one column help solve the other?
جواب
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
کارڈ 275

Which unknown should you evaluate first in a plan argument?
جواب
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
کارڈ 277

How should a trade-off between two measures be evaluated?
جواب
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
کارڈ 278

How can estimation screen answer choices before exact calculation?
جواب
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
کارڈ 279

In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
جواب
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
کارڈ 280

What should you check when two selected quantities form a ratio?
جواب
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
کارڈ 291
