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.

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

Kartu 151
Pertanyaan
When can you use the zero-product property?
Jawaban
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Kartu 152
Pertanyaan
How does an inference differ from a stated fact?
Jawaban
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Kartu 153
Pertanyaan
Does a higher percentage by itself prove a higher count?
Jawaban
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Kartu 154
Pertanyaan
What does an “or” compound inequality require?
Jawaban
The union of the solution sets. A value may satisfy either condition or both.
Kartu 155
Pertanyaan
What does a blank or omitted value establish?
Jawaban
Only that the value is not provided. It does not establish zero, no change, or failure.
Kartu 156
Pertanyaan
How do you recognize an intermediate conclusion?
Jawaban
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Kartu 157
Pertanyaan
What should you do before writing equations for a two-quantity word problem?
Jawaban
Define each variable with its unit, then translate one independent relationship per equation.
Kartu 158
Pertanyaan
Why should cross-source events be placed in time order?
Jawaban
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Kartu 159
Pertanyaan
When should candidate solutions be checked in the original equation?
Jawaban
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Kartu 160
Pertanyaan
How can switching from one measured outcome to another create a gap?
Jawaban
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Kartu 161
Pertanyaan
What makes a source relevant to a claim?
Jawaban
It supplies evidence for a required link in the claim. Related background alone is not enough.
Kartu 162
Pertanyaan
How do you solve a factored polynomial inequality reliably?
Jawaban
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Kartu 163
Pertanyaan
Does happening first prove causation?
Jawaban
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Kartu 164
Pertanyaan
How can you spot an unsupported cross-source conclusion?
Jawaban
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Kartu 165
Pertanyaan
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Jawaban
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Kartu 166
Pertanyaan
What should you verify before comparing figures from different sources?
Jawaban
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Kartu 167
Pertanyaan
How do you interpret |x − a| < r when r is positive?
Jawaban
x is within r units of a: a − r < x < a + r.
Kartu 168
Pertanyaan
What can a larger sample improve?
Jawaban
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Kartu 169
Pertanyaan
How should a cross-source recommendation be evaluated?
Jawaban
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Kartu 170
Pertanyaan
If a worker finishes one job in t hours, what is the worker's hourly rate?
Jawaban
1/t of the job per hour.
Kartu 171
Pertanyaan
What can an average hide?
Jawaban
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Kartu 172
Pertanyaan
What should you confirm before submitting a Multi-Source Reasoning answer?
Jawaban
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Kartu 173
Pertanyaan
How do you find the amount of a pure component in a mixture?
Jawaban
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Kartu 174
Pertanyaan
What role does a concession usually play?
Jawaban
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.
Kartu 175
Pertanyaan
When can an apparent cross-source discrepancy be resolved?
Jawaban
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Kartu 176
Pertanyaan
What is the two-set overlap formula?
Jawaban
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Kartu 177
Pertanyaan
What should you identify first in Table Analysis?
Jawaban
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Kartu 178
Pertanyaan
What is the fundamental counting principle?
Jawaban
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Kartu 179
Pertanyaan
Why distinguish relative change from absolute change?
Jawaban
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.
Kartu 180
Pertanyaan
How should a table filter be translated?
Jawaban
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Kartu 181
Pertanyaan
For equally likely outcomes, what is the basic probability formula?
Jawaban
Favorable outcomes divided by total possible outcomes.
Kartu 182
Pertanyaan
What makes a proposed causal mechanism useful?
Jawaban
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Kartu 183
Pertanyaan
How do you find the median?
Jawaban
Order the values and take the middle value; for an even count, average the two middle values.
Kartu 184
Pertanyaan
How should numeric values be sorted?
Jawaban
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Kartu 185
Pertanyaan
What is missed when evidence includes only successful cases?
Jawaban
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Kartu 186
Pertanyaan
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?
Jawaban
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.
Kartu 187
Pertanyaan
How should a table ratio be built when filters are involved?
Jawaban
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.
Kartu 188
Pertanyaan
What quantity is conserved when two solutions are mixed without loss?
Jawaban
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Kartu 189
Pertanyaan
When may table rows be added directly?
Jawaban
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Kartu 190
Pertanyaan
What does n! mean for a positive integer n?
Jawaban
The product of the positive integers from 1 through n.
Kartu 191
Pertanyaan
Where is the argument's logical gap?
Jawaban
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Kartu 192
Pertanyaan
How do you find the number in neither of two sets?
Jawaban
Subtract the number in the union from the total population.
Kartu 193
Pertanyaan
How should rates from table groups be combined?
Jawaban
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.
Kartu 194
Pertanyaan
What is wrong with moving from some cases to all cases?
Jawaban
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Kartu 195
Pertanyaan
When should you use a permutation?
Jawaban
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Kartu 196
Pertanyaan
Why does table granularity matter?
Jawaban
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Kartu 197
Pertanyaan
How do you find the probability that an event does not occur?
Jawaban
1 − P(event). This is often the quickest route for “at least one” questions.
Kartu 198
Pertanyaan
Why does a comparable control group help test causation?
Jawaban
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Kartu 199
Pertanyaan
How should missing table entries be treated?
Jawaban
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Kartu 200
Pertanyaan
What is the mode of a data set?
Jawaban
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.
Kartu 201
Pertanyaan
What makes a table comparison valid?
Jawaban
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.
Kartu 202
Pertanyaan
What should you check when a prediction extends a past pattern?
Jawaban
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Kartu 203
Pertanyaan
How should a drain or other undoing process enter a work-rate equation?
Jawaban
As a negative rate. Add productive rates and subtract rates that reverse the work.
Kartu 204
Pertanyaan
How can you avoid losing your place while scanning a table?
Jawaban
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Kartu 205
Pertanyaan
Can evidence that an outcome is possible show it is likely?
Jawaban
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Kartu 206
Pertanyaan
What correction is needed when counting the union of three sets?
Jawaban
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Kartu 207
Pertanyaan
When does a filtered table support a decision?
Jawaban
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Kartu 208
Pertanyaan
When should you use a combination?
Jawaban
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Kartu 209
Pertanyaan
What must support a recommendation?
Jawaban
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.
Kartu 210
Pertanyaan
How do AND and OR change a table filter?
Jawaban
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Kartu 211
Pertanyaan
How do you find the probability that independent events both occur?
Jawaban
Multiply their probabilities: P(A and B) = P(A) × P(B).
Kartu 212
Pertanyaan
What can make an alphabetical sort misleading?
Jawaban
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Kartu 213
Pertanyaan
What kind of fact most directly strengthens an argument?
Jawaban
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Kartu 214
Pertanyaan
What is the range of a data set?
Jawaban
Maximum value minus minimum value.
Kartu 215
Pertanyaan
What should you check at a filter cutoff?
Jawaban
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Kartu 216
Pertanyaan
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Jawaban
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Kartu 217
Pertanyaan
What is the most direct way to weaken an argument?
Jawaban
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Kartu 218
Pertanyaan
What does a tie in the sorted column imply?
Jawaban
The tied rows share rank on that measure. Their display order does not create a performance difference.
Kartu 219
Pertanyaan
How do you identify a useful evaluation question?
Jawaban
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Kartu 220
Pertanyaan
What should you identify first in Graphics Interpretation?
Jawaban
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Kartu 221
Pertanyaan
How do repeated identical items affect arrangement counts?
Jawaban
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Kartu 222
Pertanyaan
What should you read before estimating a plotted value?
Jawaban
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Kartu 223
Pertanyaan
How do you test whether a statement is a necessary assumption?
Jawaban
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Kartu 224
Pertanyaan
How do you find the probability that one of two mutually exclusive events occurs?
Jawaban
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Kartu 225
Pertanyaan
What should you verify in a chart legend?
Jawaban
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Kartu 226
Pertanyaan
What does standard deviation measure?
Jawaban
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Kartu 227
Pertanyaan
What standard should an inference meet?
Jawaban
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Kartu 228
Pertanyaan
What does a segment’s share depend on?
Jawaban
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Kartu 229
Pertanyaan
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Jawaban
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Kartu 230
Pertanyaan
What must a paradox explanation accomplish?
Jawaban
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Kartu 231
Pertanyaan
How is a segment in a stacked bar measured?
Jawaban
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Kartu 232
Pertanyaan
Eight students average 70 and twelve students average 80. What is the combined mean?
Jawaban
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Kartu 233
Pertanyaan
What is the difference between a graph’s level and its rate of change?
Jawaban
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Kartu 234
Pertanyaan
How should you describe a statement's role in an argument?
Jawaban
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Kartu 235
Pertanyaan
What is P(A given B)?
Jawaban
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Kartu 236
Pertanyaan
How should slope be compared across a graph?
Jawaban
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Kartu 237
Pertanyaan
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Jawaban
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Kartu 238
Pertanyaan
What should you identify first when evaluating a plan?
Jawaban
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Kartu 239
Pertanyaan
What does a trend in a scatterplot establish?
Jawaban
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Kartu 240
Pertanyaan
How can you strengthen a causal explanation?
Jawaban
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Kartu 241
Pertanyaan
How can an outlier affect a graphical trend?
Jawaban
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Kartu 242
Pertanyaan
Why do probabilities usually change when sampling without replacement?
Jawaban
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Kartu 243
Pertanyaan
One value in an n-value set increases by d. How does the mean change?
Jawaban
It increases by d/n because the total rises by d while the count stays fixed.
Kartu 244
Pertanyaan
When does a counterexample weaken a claim?
Jawaban
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Kartu 245
Pertanyaan
What is the parity of the sum of two odd integers?
Jawaban
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Kartu 246
Pertanyaan
What can an aggregate graph hide?
Jawaban
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Kartu 247
Pertanyaan
When is interpolation reasonable on a graph?
Jawaban
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Kartu 248
Pertanyaan
What makes information relevant to evaluating an argument?
Jawaban
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Kartu 249
Pertanyaan
How precise should a value read from a graph be?
Jawaban
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Kartu 250
Pertanyaan
Must a necessary assumption prove the conclusion?
Jawaban
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Kartu 251
Pertanyaan
How do you multiply positive numbers written in scientific notation?
Jawaban
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Kartu 252
Pertanyaan
How should a graph-based decision be made?
Jawaban
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Kartu 253
Pertanyaan
When is backsolving from answer choices especially useful?
Jawaban
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Kartu 254
Pertanyaan
How can axis scale distort a visual impression?
Jawaban
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Kartu 255
Pertanyaan
When should you combine two statements for an inference?
Jawaban
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Kartu 256
Pertanyaan
When is a product of integers odd?
Jawaban
Only when every factor is odd. One even factor makes the entire product even.
Kartu 257
Pertanyaan
What often resolves two apparently conflicting results?
Jawaban
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Kartu 258
Pertanyaan
How should equal distances on a logarithmic axis be interpreted?
Jawaban
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Kartu 259
Pertanyaan
Why start with a middle answer choice when backsolving ordered options?
Jawaban
Its result often eliminates half the choices at once when the relationship is monotonic.
Kartu 260
Pertanyaan
What makes a Two-Part Analysis response complete?
Jawaban
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Kartu 261
Pertanyaan
What is an analogy doing when it supports a claim?
Jawaban
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Kartu 262
Pertanyaan
How do you represent three consecutive odd integers?
Jawaban
n, n + 2, and n + 4, where n is an odd integer.
Kartu 263
Pertanyaan
What should you identify before solving Two-Part Analysis?
Jawaban
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Kartu 264
Pertanyaan
What values should you test first in a claim about an unspecified number?
Jawaban
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Kartu 265
Pertanyaan
How can an unchanged bottleneck defeat a plan?
Jawaban
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.
Kartu 266
Pertanyaan
How does the shared stem affect the two parts?
Jawaban
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Kartu 267
Pertanyaan
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Jawaban
Add 1 to each prime exponent, then multiply those results.
Kartu 268
Pertanyaan
In Two-Part Analysis, must the two selected entries be the same?
Jawaban
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.
Kartu 269
Pertanyaan
What makes evidence for a general claim strong?
Jawaban
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Kartu 270
Pertanyaan
How do you factor a difference of squares?
Jawaban
Use x² − y² = (x − y)(x + y).
Kartu 271
Pertanyaan
When should the two Two-Part Analysis selections be solved together?
Jawaban
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Kartu 272
Pertanyaan
How can one counterexample evaluate a universal claim?
Jawaban
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Kartu 273
Pertanyaan
How does an alternative explanation weaken a conclusion?
Jawaban
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Kartu 274
Pertanyaan
In Two-Part Analysis, how can one column help solve the other?
Jawaban
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Kartu 275
Pertanyaan
How do you test whether x² + bx + c factors into integer binomials?
Jawaban
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Kartu 276
Pertanyaan
Which unknown should you evaluate first in a plan argument?
Jawaban
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Kartu 277
Pertanyaan
How should a trade-off between two measures be evaluated?
Jawaban
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Kartu 278
Pertanyaan
How can estimation screen answer choices before exact calculation?
Jawaban
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Kartu 279
Pertanyaan
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Jawaban
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Kartu 280
Pertanyaan
What does a defensive assumption do?
Jawaban
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.
Kartu 281
Pertanyaan
What restriction applies when a variable appears in a denominator?
Jawaban
Exclude every value that makes the denominator zero.
Kartu 282
Pertanyaan
How does an objective differ from a constraint?
Jawaban
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Kartu 283
Pertanyaan
Which quick checks catch many Quant answer errors?
Jawaban
Check the sign, units, allowed range, and rough size against the question's conditions.
Kartu 284
Pertanyaan
What inference is safe from a statement about most members?
Jawaban
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.
Kartu 285
Pertanyaan
How should a two-part threshold rule be handled?
Jawaban
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Kartu 286
Pertanyaan
Where can one negative sign appear in a fraction without changing its value?
Jawaban
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Kartu 287
Pertanyaan
How does an argument choose between competing explanations?
Jawaban
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Kartu 288
Pertanyaan
What is an efficient way to handle two linked algebraic targets?
Jawaban
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Kartu 289
Pertanyaan
How do you solve x² = c over the real numbers?
Jawaban
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Kartu 290
Pertanyaan
What should you check when two selected quantities form a ratio?
Jawaban
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Kartu 291
Pertanyaan
How does a positive proper fraction compare with 1?
Jawaban
It is less than 1 because its numerator is smaller than its denominator.
Kartu 292
Pertanyaan
Which side effects matter when evaluating a plan?
Jawaban
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Kartu 293
Pertanyaan
How should a two-part logical claim be tested?
Jawaban
Separate the condition from the conclusion, then test whether each selected statement performs the requested role.
Kartu 294
Pertanyaan
What is the solution pattern for |x| = a over the real numbers?
Jawaban
If a > 0, x = ±a; if a = 0, x = 0; if a < 0, there is no real solution.
Kartu 295
Pertanyaan
What unit check belongs in a two-part quantitative answer?
Jawaban
Confirm that each selection has the unit requested by its column. Linked values may require different conversions.
Kartu 296
Pertanyaan
Why does user response matter to a plan?
Jawaban
The plan may depend on people adopting, following, or not avoiding it. Availability alone doesn't guarantee the needed behavior.
Kartu 297
Pertanyaan
A response rate rises from 40% to 50%. What are the percentage-point change and the relative percent increase?
Jawaban
The increase is 10 percentage points and 25% relative to the original rate: (50 − 40) ÷ 40 = 0.25.
Kartu 298
Pertanyaan
What is the final check for Two-Part Analysis?
Jawaban
Read each column prompt with its chosen entry, then verify that the pair is jointly consistent with the stem.
Kartu 299
Pertanyaan
For real x and y, what two linear cases are equivalent to x² = y²?
Jawaban
x = y or x = −y.
Kartu 300
Pertanyaan
How should benefits and costs be compared in a plan argument?
Jawaban
By their net effect on the stated goal. A plan can create the intended benefit but still fail if its relevant costs are larger.
