MCAT CARS · Get comfortable with the vocabulary.

main idea

The central claim or point that a passage as a whole is built to convey; distinct from any single supporting detail, example, or minor observation.

Related: central thesis, scope, passage structure
central thesis

The arguable position the author advances and defends, usually stated or implied near the beginning or end; what the passage exists to establish.

Related: main idea, author's purpose, argument
author's purpose

The reason the writer produced the passage, such as to persuade, explain, describe, criticize, or entertain; inferred from content, tone, and structure rather than stated outright.

Related: tone, rhetorical strategy, main idea
tone

The attitude the author conveys toward the subject, such as skeptical, admiring, cautious, or ironic; detected through word choice, emphasis, and qualification.

Related: author's purpose, connotation, rhetorical strategy
scope

The boundaries of what a passage actually covers, including the time period, population, or claims addressed; limits which inferences are legitimate versus overreaching.

Related: main idea, overreach, inference
passage structure

The arrangement of ideas across paragraphs, such as problem-solution, cause-effect, comparison, or chronology; noticing it helps locate the main point and predict where evidence sits.

Related: main idea, transition, paragraph function
paragraph function

The job a given paragraph performs for the whole passage, such as introducing a counterargument, supplying evidence, or qualifying an earlier claim; separate from its literal content.

Related: passage structure, transition, counterargument
transition

A word or phrase such as however, therefore, or moreover that signals the logical relation between ideas; often marks a shift in argument direction that the main-point question tests.

Related: passage structure, contrast signal, paragraph function
contrast signal

A cue like but, yet, although, or despite that flags a reversal or qualification; these words frequently introduce the author's actual position or a key concession.

Related: transition, concession, qualification
keyword

A repeated or emphasized word in a passage that anchors the topic and helps a reader track the author's focus; repetition often signals what the main point concerns.

Related: main idea, passage structure, scope
explicit statement

A claim written directly in the text that requires no inference; the safest basis for answering detail questions and for checking whether an inference is supported.

Related: inference, textual evidence, paraphrase
inference

A conclusion drawn from stated evidence plus reasonable assumptions; valid inferences stay within the passage's scope and require only modest, defensible steps.

Related: explicit statement, textual evidence, overreach
textual evidence

Specific words, phrases, or facts in the passage that support an answer choice; strong answers can be traced back to identifiable lines rather than general impressions.

Related: explicit statement, inference, paraphrase
paraphrase

Restating an idea in different words while preserving its meaning; correct answers often paraphrase the passage, so recognizing equivalent phrasing is essential.

Related: explicit statement, textual evidence, main idea
detail question

A question asking what the passage explicitly says about a specific fact or entity; answered by locating the relevant lines rather than by reasoning about the whole argument.

Related: explicit statement, textual evidence, paraphrase
function question

A question asking why the author mentions a particular example, quotation, or study; answered by naming its role in the argument, not by summarizing its content.

Related: paragraph function, rhetorical strategy, textual evidence
argument

A set of claims in which reasons are offered to support a conclusion; identifying the conclusion and its premises is the core of analyzing persuasive passages.

Related: premise, assumption, conclusion
conclusion

The claim an argument aims to establish, supported by the other statements; it may appear anywhere in the passage and is often flagged by therefore or thus.

Related: premise, argument, assumption
premise

A statement offered as evidence or reason in support of an argument's conclusion; premises are what the author assumes the reader will accept as grounds.

Related: conclusion, argument, assumption
assumption

An unstated belief the argument relies on for its conclusion to follow; if false, the reasoning collapses, so spotting assumptions is central to evaluating arguments.

Related: premise, conclusion, weaken
strengthen

To make an argument's conclusion more likely by adding evidence or a premise that closes a gap; the correct answer typically targets the argument's hidden assumption.

Related: weaken, assumption, argument
weaken

To make an argument's conclusion less likely by introducing evidence that undermines a premise or exposes a faulty assumption; the strongest answers attack the reasoning's weak link.

Related: strengthen, assumption, counterargument
counterargument

An opposing position raised and often rebutted by the author; recognizing it prevents mistaking the author's view for the view being criticized.

Related: concession, argument, author's purpose
concession

A point where the author acknowledges a valid opposing consideration before maintaining the main claim; concessions often appear after although or admittedly.

Related: counterargument, qualification, contrast signal
qualification

A limitation placed on a claim, such as restricting it to certain conditions or populations; it narrows the claim's scope and is often tested by scope-trap answers.

Related: scope, concession, overreach
rhetorical strategy

A deliberate technique the author uses to persuade or structure discussion, such as analogy, anecdote, appeal to authority, or rhetorical question; function questions often target these.

Related: author's purpose, tone, function question
connotation

The emotional or evaluative shading a word carries beyond its literal meaning; attention to connotation reveals the author's attitude and can distinguish answer choices.

Related: tone, author's purpose, rhetorical strategy
analogy

A comparison drawn between two situations to clarify or persuade; evaluating whether the compared cases are relevantly similar is a common reasoning task.

Related: rhetorical strategy, assumption, argument
author's attitude

The stance the writer takes toward a subject or another thinker's view, ranging from endorsement to dismissal; closely related to tone but focused on evaluative direction.

Related: tone, connotation, counterargument
application

Extending a passage's principle or finding to a new scenario not discussed in the text; the correct answer must follow from the passage's logic, not from outside knowledge.

Related: analogy, inference, scope
extrapolation

Projecting a passage's claim beyond its stated cases to predict or generalize; valid only when the new case shares the features the argument depends on.

Related: application, scope, overreach
overreach

An answer that goes beyond what the passage supports, often by adding absolute language, new causes, or broader scope; a frequent trap in inference and application questions.

Related: scope, qualification, extrapolation
outside knowledge

Information a reader brings from prior learning rather than from the passage; in CARS, answers must be justified by the text, so outside knowledge cannot be the basis.

Related: textual evidence, application, overreach
new information

Content in an answer choice that appears nowhere in the passage; usually a reason to eliminate the choice unless the question explicitly asks for an application.

Related: outside knowledge, overreach, application
analogical transfer

Applying a relationship described in the passage to a structurally similar pair of cases; the mapping must preserve the same logical relation, not merely surface similarity.

Related: analogy, application, extrapolation
hypothetical scenario

A new situation posed by a question stem and judged against the passage's principles; the task is to determine which outcome the author's reasoning would predict.

Related: application, extrapolation, analogical transfer
principle

A general rule or claim the passage endorses that can be applied to specific cases; application questions often ask which case best illustrates or violates it.

Related: application, hypothetical scenario, argument
plausibility check

Testing an answer against the passage and against common sense to see whether it could reasonably follow; eliminates choices that are logically possible but unsupported.

Related: textual evidence, overreach, inference
