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.

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

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