- main idea
- Related: topic, thesis, supporting detail
The central point a passage is built to convey about its topic. It is broader than any single detail and is usually stated or implied in the opening or closing sentences.
- topic
- Related: main idea, scope
The subject a passage is about, expressible in a short phrase. It answers what the text concerns, while the main idea answers what the author claims about that subject.
- thesis
- Related: main idea, topic sentence
The controlling claim of an argumentative or expository passage, often stated early and then defended. It differs from a topic sentence, which governs only one paragraph.
- topic sentence
- Related: thesis, supporting detail
The sentence that announces the point of a single paragraph, usually placed first. It guides the reader through that paragraph's evidence rather than the whole passage.
- supporting detail
- Related: main idea, evidence
A fact, example, statistic, or reason offered to explain or prove a broader claim. Details answer why or how, while the main idea answers what the author wants you to accept.
- inference
- Related: implication, explicit statement
A conclusion drawn from stated information plus reasonable assumptions rather than from an explicit sentence. Valid inferences must be tightly supported by the text, not merely plausible in real life.
- implication
- Related: inference, tone
A meaning a passage suggests without stating directly, often signaled by tone or word choice. Questions about implication ask what the author leaves unsaid but expects the reader to grasp.
- explicit statement
- Related: inference, textual evidence
Information stated outright in the text, requiring no inference. Recognizing explicit content prevents overreading and helps eliminate answer choices that go beyond what is written.
- textual evidence
- Related: explicit statement, supporting detail
Specific words, phrases, or sentences in a passage that justify an answer. Strong evidence can be pointed to directly and is the standard for defending a chosen option.
- author's purpose
- Related: tone, rhetorical strategy
The reason a writer produced a text, such as to inform, persuade, entertain, or instruct. Purpose shapes structure and tone and is often tested by asking why a detail was included.
- tone
- Related: mood, connotation
The attitude a writer conveys toward the subject or audience, detectable through word choice and sentence style. Tone may be critical, admiring, neutral, or skeptical without being stated.
- mood
- Related: tone, imagery
The emotional atmosphere a passage creates in the reader, distinct from the author's own attitude. Setting details and imagery often establish mood more than argument does.
- connotation
- Related: denotation, tone
The associations and emotional shading a word carries beyond its literal meaning. Words like thrifty and stingy share denotation but differ sharply in connotation.
- denotation
- Related: connotation, context clue
The literal, dictionary meaning of a word, independent of emotional associations. Reading questions sometimes hinge on the gap between a word's denotation and what the author intends.
- context clue
- Related: denotation, vocabulary in context
Surrounding text that helps a reader determine an unfamiliar word's meaning. Clues include definitions, examples, contrasts, and restatements placed near the difficult term.
- vocabulary in context
- Related: context clue, denotation
Determining a word's intended meaning from how it is used in a passage, since many words have several senses. The tested meaning may differ from the most common dictionary definition.
- transition word
- Related: logical structure, signal word
A connective such as however, therefore, or similarly that signals the logical relationship between ideas. Transitions reveal contrast, cause, addition, or sequence and guide passage structure.
- signal word
- Related: transition word, logical structure
Any word or phrase alerting the reader to an upcoming shift, emphasis, or example. Examples include but, in fact, for instance, and as a result.
- logical structure
- Related: transition word, paragraph function
The organizing pattern of a passage, such as cause-effect, comparison-contrast, chronological, or problem-solution. Recognizing structure helps locate main ideas and predict where evidence appears.
- paragraph function
- Related: logical structure, author's purpose
The role a paragraph plays in the whole passage, such as introducing, illustrating, countering, or concluding. Function questions ask what a paragraph does, not merely what it says.
- fact versus opinion
- Related: bias, evidence
The distinction between statements that can be verified and statements expressing judgment or belief. Passages often blend both, and questions test whether a claim is provable or evaluative.
- bias
- Related: fact versus opinion, tone
A slant or partiality in presentation, shown by selective evidence, loaded language, or omitted viewpoints. Detecting bias requires comparing what is emphasized with what is left out.
- argument
- Related: premise, conclusion
A set of claims in which reasons are offered to support a conclusion. A good argument links evidence to the conclusion through logic, not through assertion alone.
- premise
- Related: conclusion, assumption
A stated reason or assumption on which an argument rests. Premises supply the support; the conclusion is what the author wants accepted because of them.
- conclusion
- Related: premise, inference
The claim an argument is designed to establish, often flagged by therefore or thus. It is the point that depends on the premises rather than supporting them.
- assumption
- Related: premise, logical flaw
An unstated belief an argument needs in order to work. Identifying assumptions is central to evaluating whether reasoning is complete or leaves a gap.
- logical flaw
- Related: assumption, argument
An error in reasoning that weakens an argument, such as hasty generalization or false cause. Flaw questions ask what is wrong with how the evidence supports the conclusion.
- evidence
- Related: supporting detail, textual evidence
Data, examples, testimony, or research used to support a claim. Strong evidence is relevant, sufficient, and credible rather than merely vivid or emotionally appealing.
- compare and contrast
- Related: logical structure, analogy
A structure that examines similarities and differences between two or more subjects. It may be organized subject by subject or point by point, and questions often test which item has a given trait.
- analogy
- Related: compare and contrast, rhetorical strategy
A comparison used to explain an unfamiliar idea by likening it to a familiar one. Analogies illustrate rather than prove, so they can clarify a claim without establishing its truth.
- rhetorical strategy
- Related: author's purpose, analogy
A deliberate technique a writer uses to persuade or engage, such as anecdote, repetition, or appeal to authority. Naming the strategy helps explain how the passage achieves its effect.
- sequence
- Related: logical structure, cause and effect
The order in which events or steps are presented, often chronological or procedural. Sequence questions ask what happened first, next, or as a consequence of an earlier step.
- cause and effect
- Related: sequence, logical structure
A relationship in which one condition produces another. Passages may state causes directly or imply them, and questions test whether a reader can trace which factor produced which outcome.
- summary
- Related: main idea, paraphrase
A condensed restatement of a passage's central points in the reader's own words. A good summary captures the main idea and key support while dropping minor examples and repetition.
- paraphrase
- Related: summary, inference
Restating a specific idea or sentence in different words while preserving its meaning. Paraphrasing tests comprehension and avoids relying on the author's exact phrasing.
- scope
- Related: topic, main idea
The boundaries of what a passage covers, including time period, population, or level of generality. Answer choices that exceed the passage's scope are usually incorrect.
- reading rate
- Related: skimming, scanning
How quickly a candidate moves through a passage while retaining comprehension. Effective test takers adjust rate, skimming for structure on first pass and slowing for dense or question-relevant sections.
- skimming
- Related: scanning, reading rate
Reading quickly for gist and structure by focusing on opening sentences, headings, and transitions. Skimming precedes detailed reading and helps a candidate locate where answers are likely to appear.
- scanning
- Related: skimming, reading rate
Searching a passage rapidly for specific information such as a name, date, or keyword. Scanning is used after reading a question to return efficiently to relevant lines.
- elimination
- Related: scope, distractor
The strategy of removing clearly wrong answer choices to improve the odds among the rest. It relies on spotting choices that contradict the passage, exceed its scope, or answer a different question.
- distractor
- Related: elimination, scope
An incorrect answer choice designed to seem attractive, often by repeating passage wording or stating a true but irrelevant fact. Recognizing distractor patterns speeds up elimination.
