GRE Reading Comprehension

Reading Comprehension questions ask you to understand an argument or explanation, notice how it is built, and draw conclusions that stay within the text. You do not need to be an expert in the passage's subject. A passage may discuss science, history, public policy, or literary criticism, but the answer comes from the passage's claims and qualifications.

Read for the argument, not every detail

Begin by asking what the author is doing. Is the passage defending a claim, describing a debate, explaining a method, or revising an earlier interpretation? After each paragraph, summarize its job in a few words: introduces the conventional account, presents contrary evidence, limits the new account, or proposes a test. This map makes later questions easier because you can return to the relevant part without rereading every sentence.

Keep the central claim separate from the topic. ‘The passage is about coastal wetlands’ names the subject. ‘The author argues that wetland restoration can reduce storm damage, but only when projects reconnect tidal channels’ states a position with a condition. Questions about the main idea often distinguish a broad topic from the author's specific point.

Mark contrast words mentally. Words such as however, although, instead, and yet often signal that the author is changing direction or limiting a claim. Words such as therefore, because, and for example show a relationship between claims. The wording matters more than the topic vocabulary. A technical term may be unfamiliar, while the sentence around it explains what role it plays.

Track claims, evidence, and qualifications

Separate what the author asserts from what the author reports another person believes. A sentence such as ‘Earlier researchers attributed the pattern to temperature’ describes a view. It does not mean the current author accepts that explanation. Look for reporting verbs and transitions that show agreement, criticism, or uncertainty.

Evidence can support a claim without proving every stronger conclusion. If an experiment finds a change under one condition, the passage may not support a universal claim about every population or setting. Preserve qualifiers such as some, often, may, and under these conditions. Many wrong answers take a limited result and make it absolute.

A four-step method

1. Read the passage once for its main purpose and paragraph roles.
2. Read the question stem and identify the exact task: main idea, detail, inference, function, or author attitude.
3. Return to the relevant sentence or paragraph and state what it supports in your own words.
4. Compare every answer with that evidence, rejecting choices that add a claim, reverse a relationship, or broaden the scope.

This process is quicker than trying to memorize every detail. You are building a small map and then using it to find evidence. If a passage is short, the map can be only a few words. If it is longer and contrasts several positions, note which author or group holds each view.

Question types and how to answer them

Main idea and purpose

For a main-idea question, find the claim that covers the passage without swallowing details the author treats as secondary. An answer that repeats the first paragraph may be too narrow if later paragraphs qualify it. An answer that names the general topic may be too broad. Ask whether the author would agree that the answer describes the passage's central work.

Specific detail

For a detail question, locate the relevant phrase and read the surrounding sentence. The answer may paraphrase rather than repeat the passage's exact vocabulary. Beware of options that reuse a passage term while changing who did what, when it happened, or why it mattered.

Inference

An inference is a conclusion supported by the text, not an invitation to speculate. Combine stated facts only when the relationship is clear. If a study observes a result in two environments, you may infer that the result was observed in both. You cannot infer that it will occur in every environment unless the passage supports that reach.

Function and structure

A function question asks why a sentence, example, or paragraph appears. Describe its role in the argument: it illustrates a limitation, provides evidence for a claim, introduces a competing explanation, or answers an objection. Do not merely paraphrase its content. A sentence can report a fact while functioning as a counterexample to the previous claim.

Author attitude

Attitude questions usually require calibrated language. An author may be skeptical of one method but not reject the entire field. Words such as cautious, qualified, or critical may fit; extreme choices such as contemptuous or fully convinced often overstate the tone. Identify the sentence that signals evaluation and match its strength.

Multiple-select and select-in-passage tasks

Some GRE verbal questions ask you to select one answer, select every answer that is correct, or identify a sentence in the passage. Read the response instruction before working. In a multiple-select question, assess each choice independently. Do not stop after finding one true statement if the prompt requires all correct choices. Conversely, do not select a plausible statement that the text does not support.

For a select-in-passage task, the answer is a sentence that performs the requested role. Find the claim described by the question, then compare the candidate sentences. The sentence may be a qualification or evidence rather than the one containing the same keywords. Read enough context to distinguish the author's view from a position being summarized.

Original practice passage

For decades, urban planners treated small street trees mainly as an aesthetic feature. Recent measurements suggest that their effect on summer temperatures depends less on the number of trees than on where shade falls during the day. A row of trees can cool a sidewalk used by pedestrians while leaving nearby building walls exposed. Some researchers therefore favor planting plans based on hourly shade maps. Yet those maps do not capture every benefit of trees: residents also value visual greenery, and mature trees can intercept rainfall. A temperature model may improve heat planning, but it should not become the sole criterion for selecting planting sites.

Question 1: main idea

Which statement best expresses the passage's main point?

1. Urban tree programs should count trees rather than measure shade.
2. Hourly shade maps can improve planting decisions, but planners should consider benefits beyond temperature.
3. Researchers have shown that street trees do not affect summer temperatures.
4. Aesthetic goals and rainfall interception are the only valid reasons to plant trees.

Answer: B. The passage supports shade mapping as a useful improvement, then qualifies it by naming other benefits. A contradicts the claim about placement. C reverses the evidence. D makes two additional benefits exclusive, which the passage does not say.

Question 2: inference

Which inference is best supported?

1. A planting plan optimized for temperature may overlook some reasons residents value trees.
2. Every neighborhood has the same daytime shade pattern.
3. Mature trees cannot be included in hourly shade maps.
4. Planners previously measured rainfall interception more carefully than temperature.

Answer: A. The final sentences say temperature models do not capture every benefit and name visual greenery and rainfall interception. The passage does not claim that maps cannot represent mature trees, that neighborhoods have identical patterns, or that rainfall was measured more carefully in the past.

Question 3: function

What is the role of the final sentence?

1. It rejects the use of temperature measurements in all planning.
2. It limits the recommendation by warning against using one model as the only criterion.
3. It introduces evidence that trees increase summer temperatures.
4. It argues that rainfall matters more than shade.

Answer: B. The passage supports shade maps but says a temperature model should not control every decision. A and D overstate the qualification. C contradicts the passage.

Why attractive wrong answers fail

Wrong answers often use a true detail in a false role. ‘Trees intercept rainfall’ is true, but it is not the main claim. Another choice may preserve the subject while changing the scope: ‘all neighborhoods’ is stronger than the passage's limited measurements. A third may reverse contrast, presenting the old account as the author's conclusion.

Check four features before selecting: scope, direction, attribution, and certainty. Scope asks how broad the claim is. Direction asks whether the passage supports or challenges it. Attribution asks who holds the view. Certainty asks whether the author states a fact, a possibility, or a qualified interpretation. These checks catch many errors without requiring specialized subject knowledge.

Work efficiently under section timing

The current GRE includes 27 Verbal Reasoning questions in two sections of 18 and 23 minutes. That averages less than a minute per question across the two sections, though individual questions and passages vary. Do not spend several minutes defending an answer that lacks textual support. If two options remain, identify the exact word or inference each requires and choose the one the passage warrants.

Reading faster is not the only route to better pacing. Avoid rereading the entire passage for every question. Keep a brief paragraph map, locate the relevant claim, and verify locally. If a passage is difficult, read for structure first and return to a dense sentence when a question points there.

Practice routine

After each practice question, record the evidence that supports your answer and the reason the closest distractor fails. Classify errors: missed contrast, confused viewpoint, unsupported inference, overbroad scope, or rushed reading. Review the pattern after a set. If you repeatedly choose options that sound reasonable but go beyond the text, train yourself to ask, ‘Which exact sentence licenses this?’

Use passages from several fields so you do not depend on familiar subject matter. The goal is not to accumulate obscure facts. It is to get comfortable following an argument when the topic is new. ETS provides free GRE preparation materials, including math review; use official verbal examples to understand task directions, then practice the reasoning process with fresh passages.
