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.

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

Kart 151
Soru
When can you use the zero-product property?
Cevap
After rewriting a product equal to zero. If (x − 2)(x + 5) = 0, then x = 2 or x = −5.
Kart 152
Soru
How does an inference differ from a stated fact?
Cevap
A fact appears directly in a source; an inference must follow from the sources without an extra assumption.
Kart 153
Soru
Does a higher percentage by itself prove a higher count?
Cevap
No. The underlying totals matter. Twenty percent of 1,000 is more than fifty percent of 100.
Kart 154
Soru
What does an “or” compound inequality require?
Cevap
The union of the solution sets. A value may satisfy either condition or both.
Kart 155
Soru
What does a blank or omitted value establish?
Cevap
Only that the value is not provided. It does not establish zero, no change, or failure.
Kart 156
Soru
How do you recognize an intermediate conclusion?
Cevap
It is supported by one claim and supports another. It acts as both a conclusion and a premise in the same argument.
Kart 157
Soru
What should you do before writing equations for a two-quantity word problem?
Cevap
Define each variable with its unit, then translate one independent relationship per equation.
Kart 158
Soru
Why should cross-source events be placed in time order?
Cevap
Sequence separates prior conditions from later outcomes and prevents using future information as an earlier cause.
Kart 159
Soru
When should candidate solutions be checked in the original equation?
Cevap
Always after a step that may introduce solutions, especially squaring both sides or clearing variable denominators.
Kart 160
Soru
How can switching from one measured outcome to another create a gap?
Cevap
Evidence about one metric may not support a conclusion about another. More website visits, for example, don't by themselves mean more sales.
Kart 161
Soru
What makes a source relevant to a claim?
Cevap
It supplies evidence for a required link in the claim. Related background alone is not enough.
Kart 162
Soru
How do you solve a factored polynomial inequality reliably?
Cevap
Find the zeros, split the number line into intervals, and test each interval's sign. Include a zero only when equality is allowed.
Kart 163
Soru
Does happening first prove causation?
Cevap
No. The timing may fit a causal story, but coincidence or another cause can still explain the later event.
Kart 164
Soru
How can you spot an unsupported cross-source conclusion?
Cevap
Identify the bridge between evidence and conclusion. If the sources never establish that bridge, the conclusion needs an assumption.
Kart 165
Soru
What do 0 = 0 and 0 = 5 mean after simplifying an equation?
Cevap
0 = 0 means every allowed value is a solution; 0 = 5 means there is no solution.
Kart 166
Soru
What should you verify before comparing figures from different sources?
Cevap
Common units and denominators. Convert first, then compare the same quantity on the same basis.
Kart 167
Soru
How do you interpret |x − a| < r when r is positive?
Cevap
x is within r units of a: a − r < x < a + r.
Kart 168
Soru
What can a larger sample improve?
Cevap
Precision, if the sampling method is sound. A huge biased sample can still give a confidently wrong picture of the population.
Kart 169
Soru
How should a cross-source recommendation be evaluated?
Cevap
Apply the stated decision rule to the combined evidence. Do not substitute a personal preference for the rule.
Kart 170
Soru
If a worker finishes one job in t hours, what is the worker's hourly rate?
Cevap
1/t of the job per hour.
Kart 171
Soru
What can an average hide?
Cevap
The distribution. Two groups can share an average while differing sharply in range, concentration, or the number of extreme values.
Kart 172
Soru
What should you confirm before submitting a Multi-Source Reasoning answer?
Cevap
That every required part is supported by the correct source and scope. One unsupported component can invalidate the whole decision.
Kart 173
Soru
How do you find the amount of a pure component in a mixture?
Cevap
Concentration × total mixture amount. A 30% solution with volume 20 contains 0.30 × 20 = 6 units of the component.
Kart 174
Soru
What role does a concession usually play?
Cevap
It acknowledges a point that weighs against the conclusion, then answers that point or limits its relevance. Don't mistake the conceded claim for the argument's main conclusion.
Kart 175
Soru
When can an apparent cross-source discrepancy be resolved?
Cevap
When a stated difference in scope or method explains both figures. If no bridge is given, keep the conflict open.
Kart 176
Soru
What is the two-set overlap formula?
Cevap
In A or B = in A + in B − in both. Subtract the overlap because it was counted twice.
Kart 177
Soru
What should you identify first in Table Analysis?
Cevap
The row unit, column definitions, and any notes. This establishes what one record and each value represent.
Kart 178
Soru
What is the fundamental counting principle?
Cevap
Multiply the choices at successive stages when each stage has a fixed number of available choices.
Kart 179
Soru
Why distinguish relative change from absolute change?
Cevap
Relative change is the percentage change; absolute change is the amount added or lost. A 50% rise from 2 adds 1, while a 10% rise from 1,000 adds 100.
Kart 180
Soru
How should a table filter be translated?
Cevap
Turn it into an exact inclusion rule. Apply every condition before counting or comparing rows.
Kart 181
Soru
For equally likely outcomes, what is the basic probability formula?
Cevap
Favorable outcomes divided by total possible outcomes.
Kart 182
Soru
What makes a proposed causal mechanism useful?
Cevap
It explains how the cause could produce the effect. A plausible, evidence-backed mechanism strengthens the causal link.
Kart 183
Soru
How do you find the median?
Cevap
Order the values and take the middle value; for an even count, average the two middle values.
Kart 184
Soru
How should numeric values be sorted?
Cevap
By numerical value, not digit order. For example, 12 comes after 9 in ascending order.
Kart 185
Soru
What is missed when evidence includes only successful cases?
Cevap
The failures. Studying only surviving firms can make a strategy look safer or more effective than it is.
Kart 186
Soru
Two machines have stated constant rates of 1/3 and 1/5 job per hour and operate simultaneously without interference. May their rates be added?
Cevap
Yes. The stated rates are constant and the machines do not interfere, so their combined rate is 1/3 + 1/5 = 8/15 job per hour.
Kart 187
Soru
How should a table ratio be built when filters are involved?
Cevap
Derive the numerator and denominator separately from the question, then apply each filter only where it is relevant. Do not automatically filter both quantities or default to all rows.
Kart 188
Soru
What quantity is conserved when two solutions are mixed without loss?
Cevap
The amount of the pure component. Set the sum of the starting component amounts equal to the final component amount.
Kart 189
Soru
When may table rows be added directly?
Cevap
Only when they are disjoint parts of the same measure and use compatible units. Overlapping groups would be double-counted.
Kart 190
Soru
What does n! mean for a positive integer n?
Cevap
The product of the positive integers from 1 through n.
Kart 191
Soru
Where is the argument's logical gap?
Cevap
Between the evidence and the conclusion. State what must connect them without merely repeating either side.
Kart 192
Soru
How do you find the number in neither of two sets?
Cevap
Subtract the number in the union from the total population.
Kart 193
Soru
How should rates from table groups be combined?
Cevap
Divide the total numerator by the total denominator. Weight a group rate by its group size only when that size is the rate's denominator.
Kart 194
Soru
What is wrong with moving from some cases to all cases?
Cevap
The conclusion is broader than the evidence. Evidence that some members have a trait doesn't show that every member does.
Kart 195
Soru
When should you use a permutation?
Cevap
When selecting and arranging items and order matters. The number of ordered selections of r from n distinct items is n!/(n − r)!.
Kart 196
Soru
Why does table granularity matter?
Cevap
A row-level fact may disappear or change after aggregation. Match the claim to the table’s level of detail.
Kart 197
Soru
How do you find the probability that an event does not occur?
Cevap
1 − P(event). This is often the quickest route for “at least one” questions.
Kart 198
Soru
Why does a comparable control group help test causation?
Cevap
It shows what happened without the suspected cause. If the groups differ mainly in that factor, the result is harder to explain another way.
Kart 199
Soru
How should missing table entries be treated?
Cevap
As unknown unless the notes define another meaning. Exclude or include them only as the question directs.
Kart 200
Soru
What is the mode of a data set?
Cevap
A mode is any value with the greatest frequency. Under the no-mode convention, there is no mode only when at least two distinct values all have equal frequency.
Kart 201
Soru
What makes a table comparison valid?
Cevap
The values must have compatible measures, units, periods, populations, and definitions. Normalize only validly convertible differences; reject differences in population, period, or definition that cannot be reconciled.
Kart 202
Soru
What should you check when a prediction extends a past pattern?
Cevap
Whether the conditions behind the past pattern will continue. A trend alone doesn't show that its causes will remain in place.
Kart 203
Soru
How should a drain or other undoing process enter a work-rate equation?
Cevap
As a negative rate. Add productive rates and subtract rates that reverse the work.
Kart 204
Soru
How can you avoid losing your place while scanning a table?
Cevap
Evaluate one condition at a time and mark qualifying rows mentally or on the scratchpad. Count only after the final filter.
Kart 205
Soru
Can evidence that an outcome is possible show it is likely?
Cevap
No. Possibility only shows that an outcome can occur; probability requires evidence about how likely it is.
Kart 206
Soru
What correction is needed when counting the union of three sets?
Cevap
Add the three individual counts, subtract all three pairwise overlaps, then add the triple overlap back once.
Kart 207
Soru
When does a filtered table support a decision?
Cevap
When the qualifying rows satisfy the stated rule. Keep filtering, calculation, and decision as separate steps.
Kart 208
Soru
When should you use a combination?
Cevap
When selecting items and order does not matter. The number of selections of r from n distinct items is n!/[r!(n − r)!].
Kart 209
Soru
What must support a recommendation?
Cevap
A link from the proposed action to the stated goal. The argument also needs the action to be feasible and free of costs that defeat the goal.
Kart 210
Soru
How do AND and OR change a table filter?
Cevap
AND requires every condition; OR requires at least one. Parenthesize mixed rules before scanning rows.
Kart 211
Soru
How do you find the probability that independent events both occur?
Cevap
Multiply their probabilities: P(A and B) = P(A) × P(B).
Kart 212
Soru
What can make an alphabetical sort misleading?
Cevap
Labels may contain categories or embedded numbers. Confirm whether the column is text, numeric, or chronological.
Kart 213
Soru
What kind of fact most directly strengthens an argument?
Cevap
A fact that supports the missing link between evidence and conclusion. Merely repeating a premise adds little.
Kart 214
Soru
What is the range of a data set?
Cevap
Maximum value minus minimum value.
Kart 215
Soru
What should you check at a filter cutoff?
Cevap
Whether the boundary is inclusive. “At least 40” includes 40; “more than 40” does not.
Kart 216
Soru
A train covers 150 miles in 3 hours at a constant rate. What is its rate?
Cevap
50 miles per hour. Rearrange distance = rate × time to get rate = 150 ÷ 3.
Kart 217
Soru
What is the most direct way to weaken an argument?
Cevap
Undermine a necessary assumption connecting the evidence to the conclusion. The premises can remain true while the conclusion loses support.
Kart 218
Soru
What does a tie in the sorted column imply?
Cevap
The tied rows share rank on that measure. Their display order does not create a performance difference.
Kart 219
Soru
How do you identify a useful evaluation question?
Cevap
Test whether opposite answers would push the argument in opposite directions. If both answers leave the conclusion unchanged, the question isn't useful.
Kart 220
Soru
What should you identify first in Graphics Interpretation?
Cevap
The chart type and what each visual encoding represents. Bars, lines, areas, and points support different readings.
Kart 221
Soru
How do repeated identical items affect arrangement counts?
Cevap
For n total items, divide n! by the factorial of each repeated count. Identical items do not create new arrangements when swapped.
Kart 222
Soru
What should you read before estimating a plotted value?
Cevap
Both axis labels, units, and category order. Position has meaning only after the axes are understood.
Kart 223
Soru
How do you test whether a statement is a necessary assumption?
Cevap
Negate it. If that negation seriously damages the argument, the original statement was necessary.
Kart 224
Soru
How do you find the probability that one of two mutually exclusive events occurs?
Cevap
Add their probabilities: P(A or B) = P(A) + P(B). Their overlap is zero.
Kart 225
Soru
What should you verify in a chart legend?
Cevap
Which color, shape, or line maps to each series. Similar styling can otherwise swap the groups in your interpretation.
Kart 226
Soru
What does standard deviation measure?
Cevap
How spread out values are around the mean. Greater dispersion means a larger standard deviation.
Kart 227
Soru
What standard should an inference meet?
Cevap
It must follow from the given statements, without extra assumptions. Choose the modest claim the evidence guarantees.
Kart 228
Soru
What does a segment’s share depend on?
Cevap
The correct whole. A category’s share of one region may differ from its share of the full dataset.
Kart 229
Soru
For motion along the same line, when do you add or subtract two speeds to get relative speed?
Cevap
Add the speeds for opposite directions; subtract the smaller speed from the larger for the same direction.
Kart 230
Soru
What must a paradox explanation accomplish?
Cevap
Make both surprising facts plausible at the same time. Rejecting either stated fact doesn't resolve the tension.
Kart 231
Soru
How is a segment in a stacked bar measured?
Cevap
Subtract its lower boundary from its upper boundary. The upper endpoint alone is cumulative, not the segment value.
Kart 232
Soru
Eight students average 70 and twelve students average 80. What is the combined mean?
Cevap
- The group sizes are the weights: (8 × 70 + 12 × 80) ÷ 20 = 76.
Kart 233
Soru
What is the difference between a graph’s level and its rate of change?
Cevap
Level is the plotted value; rate of change is the slope. A high line can still be falling.
Kart 234
Soru
How should you describe a statement's role in an argument?
Cevap
Describe what it does, not just what it says. It may support the conclusion, present an objection, answer that objection, or illustrate a principle.
Kart 235
Soru
What is P(A given B)?
Cevap
P(A and B) / P(B), provided P(B) > 0. Restrict the sample space to outcomes in B.
Kart 236
Soru
How should slope be compared across a graph?
Cevap
Use change in vertical value divided by change in horizontal value. Visual steepness is reliable only on the same scales.
Kart 237
Soru
A driver covers equal distances at 30 mph and 60 mph. Is the average speed 45 mph?
Cevap
No. Using 60 miles for each leg gives 120 miles in 3 hours, so the average speed is 40 mph.
Kart 238
Soru
What should you identify first when evaluating a plan?
Cevap
The plan's exact goal and success measure. A proposal can produce benefits yet still fail its stated objective.
Kart 239
Soru
What does a trend in a scatterplot establish?
Cevap
An association in the displayed data. It does not by itself establish causation or predict every individual point.
Kart 240
Soru
How can you strengthen a causal explanation?
Cevap
Rule out a credible alternative cause, support the proposed mechanism, or show the effect changes when the proposed cause changes.
Kart 241
Soru
How can an outlier affect a graphical trend?
Cevap
It can pull a summary line or average away from the main cluster. Check whether the claim concerns all points or the typical pattern.
Kart 242
Soru
Why do probabilities usually change when sampling without replacement?
Cevap
The sample space changes after each draw. Update both the favorable count and the total before multiplying conditional probabilities.
Kart 243
Soru
One value in an n-value set increases by d. How does the mean change?
Cevap
It increases by d/n because the total rises by d while the count stays fixed.
Kart 244
Soru
When does a counterexample weaken a claim?
Cevap
When the claim requires the counterexample not to exist. One genuine exception can defeat an absolute claim, but may barely affect a modest one.
Kart 245
Soru
What is the parity of the sum of two odd integers?
Cevap
Even. Each odd integer is one more than an even integer, so the two extra ones add to 2.
Kart 246
Soru
What can an aggregate graph hide?
Cevap
Differences among subgroups or periods. A stable total can coexist with large offsetting changes inside it.
Kart 247
Soru
When is interpolation reasonable on a graph?
Cevap
When the graph implies continuity between nearby points. Do not interpolate across separate categories.
Kart 248
Soru
What makes information relevant to evaluating an argument?
Cevap
It bears on the uncertain link the conclusion depends on. Interesting facts about the topic may still be logically irrelevant.
Kart 249
Soru
How precise should a value read from a graph be?
Cevap
Only as precise as the scale supports. Use a defensible interval when the mark falls between ticks.
Kart 250
Soru
Must a necessary assumption prove the conclusion?
Cevap
No. It only has to be required for the argument to work; it need not be enough to establish the conclusion on its own.
Kart 251
Soru
How do you multiply positive numbers written in scientific notation?
Cevap
Multiply the coefficients, add the powers of 10, then adjust the coefficient to be at least 1 and less than 10.
Kart 252
Soru
How should a graph-based decision be made?
Cevap
Translate the visual into values or bounds, then apply the stated rule. Do not decide from appearance alone.
Kart 253
Soru
When is backsolving from answer choices especially useful?
Cevap
When the choices are concrete values and direct algebra is slower than testing them in the original conditions.
Kart 254
Soru
How can axis scale distort a visual impression?
Cevap
Unequal intervals or a truncated baseline can magnify or compress differences. Use tick values, not apparent distance alone.
Kart 255
Soru
When should you combine two statements for an inference?
Cevap
When they share a term or relationship that creates a guaranteed consequence. Don't combine them through an unstated causal or statistical link.
Kart 256
Soru
When is a product of integers odd?
Cevap
Only when every factor is odd. One even factor makes the entire product even.
Kart 257
Soru
What often resolves two apparently conflicting results?
Cevap
A hidden difference in group, time, measurement, or conditions. The results may describe different slices of the situation.
Kart 258
Soru
How should equal distances on a logarithmic axis be interpreted?
Cevap
As equal multiplicative changes, not equal absolute changes. Read the labeled values before comparing gaps.
Kart 259
Soru
Why start with a middle answer choice when backsolving ordered options?
Cevap
Its result often eliminates half the choices at once when the relationship is monotonic.
Kart 260
Soru
What makes a Two-Part Analysis response complete?
Cevap
Both selections must satisfy their own column prompts under the same stem. Treat the pair as one submitted response.
Kart 261
Soru
What is an analogy doing when it supports a claim?
Cevap
It argues that because two cases share relevant features, a result or principle from one likely applies to the other.
Kart 262
Soru
How do you represent three consecutive odd integers?
Cevap
n, n + 2, and n + 4, where n is an odd integer.
Kart 263
Soru
What should you identify before solving Two-Part Analysis?
Cevap
The role of each column. One may ask for a condition while the other asks for a consequence or decision.
Kart 264
Soru
What values should you test first in a claim about an unspecified number?
Cevap
Test allowed categories that may behave differently: positive, negative, zero, fractional, and boundary values.
Kart 265
Soru
How can an unchanged bottleneck defeat a plan?
Cevap
Improving a nonlimiting step won't improve the final outcome if another constraint still controls it. Faster ordering doesn't help when production is already full.
Kart 266
Soru
How does the shared stem affect the two parts?
Cevap
Its definitions and constraints apply to both. Keep them fixed while testing each column’s requirement.
Kart 267
Soru
How do you count the positive divisors of an integer greater than 1 from its prime factorization?
Cevap
Add 1 to each prime exponent, then multiply those results.
Kart 268
Soru
In Two-Part Analysis, must the two selected entries be the same?
Cevap
In the current format, the two selected entries may be the same or different. A linkage in the stem determines whether you must reason through them jointly, not whether their values match.
Kart 269
Soru
What makes evidence for a general claim strong?
Cevap
It should be relevant and reliable and, if case-based, come from representative cases. More evidence isn't automatically better evidence.
Kart 270
Soru
How do you factor a difference of squares?
Cevap
Use x² − y² = (x − y)(x + y).
Kart 271
Soru
When should the two Two-Part Analysis selections be solved together?
Cevap
When one shared relationship constrains both. Test candidate pairs against that relationship instead of solving isolated fragments.
Kart 272
Soru
How can one counterexample evaluate a universal claim?
Cevap
One valid counterexample disproves a claim that is supposed to hold for every allowed value.
Kart 273
Soru
How does an alternative explanation weaken a conclusion?
Cevap
It shows that the evidence can be true without the proposed explanation being true. The alternative must account for the same result.
Kart 274
Soru
In Two-Part Analysis, how can one column help solve the other?
Cevap
A valid selection can narrow the remaining candidates when the parts share a constraint. Recheck the final pair in both columns.
Kart 275
Soru
How do you test whether x² + bx + c factors into integer binomials?
Cevap
Look for integers r and s with r + s = b and rs = c. If they exist, the factorization is (x + r)(x + s).
Kart 276
Soru
Which unknown should you evaluate first in a plan argument?
Cevap
A condition that could make the plan achieve or miss its goal. Focus on feasibility, response, costs, and side effects tied to that goal.
Kart 277
Soru
How should a trade-off between two measures be evaluated?
Cevap
Apply the stated priorities or limits. An option is better only relative to the rule, not because one measure is largest.
Kart 278
Soru
How can estimation screen answer choices before exact calculation?
Cevap
Approximate the expression's magnitude, then eliminate choices that are far too large or too small.
Kart 279
Soru
In a constrained-decision Two-Part Analysis problem, what should you check before comparing candidates?
Cevap
Check every hard constraint first. Discard any option that breaks a required limit, then compare only the feasible candidates.
Kart 280
Soru
What does a defensive assumption do?
Cevap
It rules out a threat that would break the argument. For example, a revenue plan may assume that its added costs won't exceed the new revenue.
Kart 281
Soru
What restriction applies when a variable appears in a denominator?
Cevap
Exclude every value that makes the denominator zero.
Kart 282
Soru
How does an objective differ from a constraint?
Cevap
A constraint determines what is allowed; an objective ranks the allowed options. Apply them in that order.
Kart 283
Soru
Which quick checks catch many Quant answer errors?
Cevap
Check the sign, units, allowed range, and rough size against the question's conditions.
Kart 284
Soru
What inference is safe from a statement about most members?
Cevap
More than half have the stated trait. You can't infer that all do, that any particular member does, or that most have another trait.
Kart 285
Soru
How should a two-part threshold rule be handled?
Cevap
Translate each threshold with the correct inequality, including its boundary. Then test both selected values against it.
Kart 286
Soru
Where can one negative sign appear in a fraction without changing its value?
Cevap
Before the fraction, in the numerator, or in the denominator: −(a/b) = (−a)/b = a/(−b), provided b ≠ 0.
Kart 287
Soru
How does an argument choose between competing explanations?
Cevap
It presents evidence that one explanation handles better than the others, often by ruling out a rival prediction.
Kart 288
Soru
What is an efficient way to handle two linked algebraic targets?
Cevap
Express both in terms of one variable or invariant. Evaluate candidate values only after the relationship is clear.
Kart 289
Soru
How do you solve x² = c over the real numbers?
Cevap
If c > 0, x = ±√c; if c = 0, x = 0; if c < 0, there is no real solution.
Kart 290
Soru
What should you check when two selected quantities form a ratio?
Cevap
Order and scale. The ratio A:B is not interchangeable with B:A, and proportional pairs may all fit.
Kart 291
Soru
How does a positive proper fraction compare with 1?
Cevap
It is less than 1 because its numerator is smaller than its denominator.
Kart 292
Soru
Which side effects matter when evaluating a plan?
Cevap
Effects that change the plan's net result or work against its goal. A small unrelated inconvenience usually doesn't matter.
Kart 293
Soru
How should a two-part logical claim be tested?
Cevap
Separate the condition from the conclusion, then test whether each selected statement performs the requested role.
Kart 294
Soru
What is the solution pattern for |x| = a over the real numbers?
Cevap
If a > 0, x = ±a; if a = 0, x = 0; if a < 0, there is no real solution.
Kart 295
Soru
What unit check belongs in a two-part quantitative answer?
Cevap
Confirm that each selection has the unit requested by its column. Linked values may require different conversions.
Kart 296
Soru
Why does user response matter to a plan?
Cevap
The plan may depend on people adopting, following, or not avoiding it. Availability alone doesn't guarantee the needed behavior.
Kart 297
Soru
A response rate rises from 40% to 50%. What are the percentage-point change and the relative percent increase?
Cevap
The increase is 10 percentage points and 25% relative to the original rate: (50 − 40) ÷ 40 = 0.25.
Kart 298
Soru
What is the final check for Two-Part Analysis?
Cevap
Read each column prompt with its chosen entry, then verify that the pair is jointly consistent with the stem.
Kart 299
Soru
For real x and y, what two linear cases are equivalent to x² = y²?
Cevap
x = y or x = −y.
Kart 300
Soru
How should benefits and costs be compared in a plan argument?
Cevap
By their net effect on the stated goal. A plan can create the intended benefit but still fail if its relevant costs are larger.
