GRE Reading Comprehension: Contradiction Questions

Most GRE Reading Comprehension questions ask you to find what a passage supports or implies. Contradiction questions flip the logic: you must identify the statement that the passage proves false. The critical skill is distinguishing three categories — statements the passage supports, statements the passage is silent on, and statements the passage actively contradicts. Only the third category is correct. Below you will learn the three- category framework, work through two interactive examples, and then practice with five guided questions drawn from the same logical reasoning skills.

What Are Contradiction Questions?

Contradiction questions ask you to identify which answer choice directly opposes or contradicts information presented in the passage. Unlike most Reading Comprehension questions that ask you to find what the passage supports or implies, Contradiction questions require you to find the statement that the passage's information proves false, or that is incompatible with what the passage states.

Common question stems include: "Which of the following statements directly contradicts the information presented above?", "Which statement is inconsistent with the information in the passage?", and "Which of the following is contradicted by the passage?" The response format is always Select One with five choices (A through E).

Frequency note: Contradiction is one of the less common Reading Comprehension subtypes on the GRE. You may encounter zero or one on a given test. However, the underlying skill — distinguishing what a passage contradicts from what it merely does not mention — is fundamental to all RC question types, including Inference, Supporting Detail, and Strengthen/ Weaken.

The Three-Category Framework

Every answer choice on a Contradiction question falls into exactly one of three categories. Recognizing which category each choice belongs to is the single most important skill for this question type.

Consistent with the Passage

The answer agrees with what the passage says. Since the question asks for a contradiction, anything consistent is wrong. Eliminate it.

Neither Supported nor Contradicted

The answer discusses something the passage does not address. It cannot be a contradiction if the passage is silent on the topic. Eliminate it. This is where most test-takers make mistakes.

Directly Contradicted by the Passage

The passage provides information that makes this statement false. This is the only correct category. The answer states something provably false based on the passage — not just unlikely or unmentioned.

The key distinction: "Not mentioned" does NOT equal "contradicted." An answer that the passage does not discuss is in Category 2, not Category 3. Silence equals "cannot determine," not "proven false." This is the single most common error on Contradiction questions.

How to Solve Contradiction Questions Step by Step

These five strategies apply to all Contradiction questions. Work through them in order and you will avoid the most common errors.

After reading the passage, list its specific assertions. What does the passage state as fact? These are what the answer choices will be tested against. Do not confuse opinions or speculations with factual claims unless the passage explicitly attributes them as established findings.

Ask yourself: "What must be true if these facts are all correct?" The harder Contradiction questions target logical consequences of stated facts, not the facts themselves. List these implied claims alongside the stated ones.

For each choice, ask: "Does the passage provide information that makes this statement false?" If yes, it is a contradiction (Category 3). If the choice agrees with the passage, it is consistent (Category 1). If the passage says nothing about the topic, it is unaddressed (Category 2).

The correct answer will state the opposite of something the passage says. If the passage says "X increased," the contradicting answer will say "X decreased." If the passage says first-year ice is salty, the contradiction will say it is not salty. Look for reversed relationships, negated claims, and flipped comparisons.

Words like "general population" vs. "labor force," specific date ranges, and geographic qualifiers define the boundaries of claims. A statement cannot contradict a claim if it falls outside that claim's scope. Match the answer choice's scope precisely to the passage's scope before deciding.

Pro tip: If you find yourself drawn to an answer simply because it "sounds wrong" or seems implausible, step back. The correct answer must be provably false based on the passage's information — not just unlikely or unfamiliar. Always point to the specific passage claim that the answer contradicts.

Worked Example: Explicit Contradiction

This example tests an explicit contradiction — the passage directly states a fact, and the correct answer directly reverses it. Work through each step below to build the three-category classification skill.

Arctic Sea Ice: Identifying a Reversed Claim

Passage: "Arctic sea ice comes in two varieties. Seasonal ice forms in winter and then melts in summer, while perennial ice persists year-round. To the untrained eye, all sea ice looks similar, but by licking it, one can estimate how long a particular piece has been floating around. A piece of first-year ice will taste salty. Eventually, if the ice survives, pockets of brine drain out through fine, veinlike channels, and the ice becomes fresher; multiyear ice can even be melted and drunk."

Which of the following statements is contradicted by the passage?

Seasonal ice is visually indistinguishable from perennial ice to a non-expert

First-year ice contains a higher concentration of brine than multiyear ice

Perennial ice tastes saltier than first-year ice

The channels through which brine drains are fine and veinlike in structure

Multiyear ice has lost enough salt that it can be melted and consumed as drinking water

Step 1: List the passage's key claims

Which of the following is a factual claim the passage makes?

Step 2: Identify the implied claim about saltiness

Step 3: Classify 'Seasonal ice is visually indistinguishable from perennial ice to a non-expert'

Step 4: Classify 'The channels through which brine drains are fine and veinlike in structure'

Step 5: Classify 'Perennial ice tastes saltier than first-year ice'

Worked Example: Implicit Contradiction

This example tests an implicit contradiction — the passage states facts whose logical consequence is X, and the correct answer states not-X. You must work out the implication before recognizing the contradiction.

U.S. Farmers: Identifying an Implied Contradiction

Passage: "In the United States between 1850 and 1880, the number of farmers continued to increase, but at a rate lower than that of the general population."

Which of the following statements directly contradicts the information presented above?

The number of farmers in the United States increased between 1850 and 1880

The proportion of farmers in the labor force decreased from 64% to 49% between 1850 and 1880

The general population of the United States grew between 1850 and 1880

The proportion of farmers in the general population increased from 68% to 72% between 1850 and 1880

The rate of growth among farmers was not the highest of any occupational group during this period

Step 1: Identify the two stated facts

The passage states two facts. Which pair is correct?

Step 2: Work out the implied consequence

Step 3: Classify 'The number of farmers in the United States increased between 1850 and 1880'

Step 4: Classify 'The proportion of farmers in the labor force decreased from 64% to 49%'

Step 5: Classify 'The proportion of farmers in the general population increased from 68% to 72%'

Practice Questions

Now apply what you have learned. Each question below presents a short passage followed by a Contradiction question stem. Identify which answer choice is directly contradicted by the passage -- that is, which statement the passage proves false. After you submit your answer, click through the solution one step at a time to compare against your own reasoning.

Question 1 — Explicit Contradiction

Passage: The monarch butterfly's annual migration between its summer breeding grounds in Canada and the United States and its winter refuge in the oyamel fir forests of central Mexico spans up to 4,500 kilometers. Unlike most migratory species, monarchs do not return to the same sites they visited the previous year; a single butterfly completes only one leg of the round trip in its lifetime. The butterflies that arrive in Mexico each autumn are, on average, four generations removed from those that departed Mexico the previous spring.

Which of the following statements is directly contradicted by the passage above?

Question 2 — Implied Contradiction

Passage: Deep-sea hydrothermal vents were first discovered in 1977 along the Galapagos Rift. Unlike virtually all other known ecosystems, which ultimately depend on photosynthesis to convert solar energy into organic matter, the vent communities draw their energy from chemosynthesis: bacteria oxidize hydrogen sulfide released by the vents to produce organic compounds. These bacteria form the base of an elaborate food web that supports tube worms, crustaceans, and fish at depths where sunlight never penetrates.

Which of the following is contradicted by the passage?

Question 3 — Scope and Category Distinction

Passage: Roman engineers produced a form of concrete — known as opus caementicium — by mixing volcanic ash called pozzolana with lime and seawater. Unlike modern Portland cement, which weakens when exposed to seawater, Roman concrete actually grows stronger over time in marine environments: seawater penetrating microfractures triggers a chemical reaction that forms interlocking crystalline structures within the material. Structures such as the Pantheon's dome and the harbors of Caesarea Maritima have survived more than two millennia.

Which of the following statements is contradicted by the passage?

Question 4 — Contradicting a Stated Relationship

Passage: Hummingbirds have the highest mass-specific metabolic rate of any homeothermic (warm-blooded) animal. To sustain their rapid wing beats — up to 80 beats per second in some species — they must consume roughly their own body weight in nectar each day. At night, when feeding is impossible, hummingbirds enter a state called torpor: their body temperature drops from approximately 40°C to near ambient temperature, and their heart rate falls from over 1,000 beats per minute to as few as 50. Torpor reduces overnight energy expenditure by more than 90 percent.

Which of the following is contradicted by the passage?

Question 5 — Distinguishing Unaddressed from Contradicted

Passage: Genetic sequencing of ancient DNA has revealed that modern humans of non-African descent carry, on average, between one and four percent Neanderthal DNA, the result of interbreeding that occurred when anatomically modern humans migrated out of Africa and encountered Neanderthal populations in Europe and western Asia. Populations indigenous to sub-Saharan Africa, whose ancestors did not participate in these out-of-Africa migrations, carry no detectable Neanderthal DNA. Researchers have identified several Neanderthal-derived gene variants in modern humans that appear to influence immune function and skin pigmentation.

Which of the following is contradicted by the passage?

Four Common Traps

Trap 1 — Consistent answer disguised as a contradiction. The answer actually agrees with the passage but uses different wording that makes it seem like it might conflict. Always reread the passage's relevant claim and verify that the answer genuinely opposes it, not just rephrases it.

Trap 2 — Unaddressed topic mistaken for contradiction. The answer concerns something the passage does not discuss at all. Because the statement sounds wrong or unfamiliar, test- takers assume it must be contradicted. Remember: if the passage is silent on a topic, the statement is in Category 2, not Category 3. Silence does not equal contradiction.

Trap 3 — Wrong scope. The answer discusses the labor force when the passage only discusses the general population (or some similar scope mismatch). Match the answer's scope precisely to the passage's scope. Claims about different populations, time periods, or geographic regions cannot be contradicted by a passage that addresses a different scope.

Trap 4 — Partially consistent answer. Part of the answer aligns with the passage, making it seem compatible when it actually contradicts the passage on a specific point. Evaluate the entire answer choice — not just the part that sounds familiar. A statement can be half-right and still be the correct contradiction if it reverses a specific claim.

Explicit vs. Implicit Contradictions

Contradictions in GRE passages fall into two categories, and the harder questions test the second. Understanding both is essential for thorough preparation.

Type	How It Works	Difficulty
Explicit	The passage directly states X. The correct answer directly states not-X. The contradiction is immediately visible.	Medium
Implicit	The passage states facts whose logical consequence is X. The correct answer states not-X. You must work out the implication before recognizing the contradiction.	Hard

How to handle implicit contradictions

After reading the passage, ask: "What must be true if these facts are all correct?" List the logical consequences of the passage's stated facts. Then test each answer choice against both the stated facts AND their logical consequences. The correct answer on harder questions often targets the logical consequence rather than the stated fact itself.

Example of an implicit contradiction: If a passage says "the number of farmers increased, but at a rate lower than the general population," the implied consequence is that the proportion of farmers decreased. An answer claiming "the proportion of farmers increased" contradicts the implication, not a directly stated fact. You must derive the implication first.

Related Subtypes

The Contradiction skill is closely related to several other RC question types. Practicing contradictions strengthens your ability across all of them.

Subtype	Relationship to Contradiction
Supporting Detail	Supporting Detail asks what the passage states as true; Contradiction asks what the passage proves false. They are logical inverses.
Inference	Inference asks what can be logically concluded; Contradiction asks what is logically incompatible. Both require going beyond the literal text.
Strengthen/Weaken	Weaken questions ask for information that contradicts an argument's reasoning or assumptions. They use the same analytical skill as Contradiction but in an argument context.
Comparison/Distinction	Both can involve testing claims about relationships between entities. A reversed comparison (saying X > Y when the passage implies Y > X) is a common form of contradiction.

Frequently Asked Questions

How often do Contradiction questions appear on the GRE?

Contradiction is one of the less common Reading Comprehension subtypes on the GRE. You may encounter zero or one on a given test. However, the underlying skill — distinguishing what a passage contradicts from what it merely does not mention — is fundamental to all RC question types, making this a high-value area to practice.

What is the difference between "not supported" and "contradicted" on the GRE?

A statement that is "not supported" is one the passage does not mention or imply — the passage is silent on the topic. A statement that is "contradicted" is one the passage provides information that proves false. The most common mistake is treating silence as contradiction. If the passage does not discuss wages, an answer about wages cannot be a contradiction — the passage simply has nothing to say on the matter.

Can a contradiction target an implied claim rather than a directly stated fact?

Yes. Harder Contradiction questions target logical consequences of stated facts rather than the facts themselves. For example, if a passage says farmers grew in number but at a rate lower than the general population, the implied consequence is that the proportion of farmers decreased. An answer claiming the proportion increased contradicts this implication. You must work out the logical consequence before recognizing the contradiction.

How do I avoid scope traps in Contradiction questions?

Pay close attention to scope markers such as "general population" versus "labor force," specific time periods like "between 1850 and 1880," and geographic qualifiers. A statement cannot contradict a passage claim if it falls outside the scope of that claim. Before selecting an answer, confirm that the passage actually makes a claim about the specific topic, population, or time period in the answer choice.

What strategies work best for Contradiction questions?

First, list the passage's key factual claims and their logical consequences. Then classify each answer choice into one of three categories: consistent with the passage, not addressed by the passage, or directly contradicted by the passage. Only the third category is correct. Eliminate choices about topics the passage does not discuss — silence does not equal contradiction. For the remaining choices, point to the specific passage claim each one reverses before selecting your answer.
