Rank 3 by frequency | 263 questions in corpus (10.6% of all questions)
Asks the test-taker to identify the passage's central argument or thesis — the single overarching claim that the entire passage is organized around. This is the "big picture" comprehension question. The correct answer must capture the passage's core argument, not just a supporting detail or secondary theme. For comparative passages, asks what central topic or question both passages address.
Main Point is the most formulaic question type — 238 of 263 stems (90%) use nearly identical phrasing. Despite this, there are 5 identifiable subtypes:
The dominant phrasing, used with almost no variation. - "Which one of the following most accurately states the main point of the passage?" - "Which one of the following best expresses the main idea of the passage?" - "Which one of the following best states the main idea of the passage?" - "Which one of the following most accurately expresses the main point of the passage?"
What makes it distinct: The question is asking for the content of the central argument — a substantive claim the passage makes.
What makes it distinct: Uses "thesis" rather than "main point" — functionally identical but signals a more academic register.
What makes it distinct: "Central idea" is slightly broader than "main point" — it may encompass both the argument and the conceptual framework, not just the thesis statement.
What makes it distinct: "Summarizes the content" asks for a compressed version of the whole passage, not just the thesis. The correct answer must capture both the argument and its major support.
What makes it distinct: For comparative passages, the question asks about the shared topic or central concern that both passages address. The answer describes a question or issue, not a thesis.
The question writer identifies the single claim that: - Is stated or strongly implied in the passage (usually in the first or last paragraph) - Everything else in the passage is organized to support, explain, or develop - Could serve as a one-sentence summary of the author's argument - Is the author's own view (not a view the author describes and rejects)
The correct answer must: - Capture the scope of the passage — not too narrow (a single detail) or too broad (a generalization beyond the passage) - Include the direction of the argument — not just the topic but the author's position on it - Be balanced — if the passage makes a nuanced argument ("X is beneficial in some ways but problematic in others"), the correct answer must reflect that nuance - Use accurate language — no distortions, exaggerations, or omissions of key qualifiers
Correct answers for Main Point are the longest of any type (average 24.3 words) because they must compress a full argument into a single statement.
Trap Type 1: Too Narrow (Detail Masquerading as Main Point) States a supporting detail or one paragraph's argument as if it were the main point. Example: If the passage argues "New archaeological methods have transformed our understanding of ancient civilizations," a too-narrow answer might say "Radiocarbon dating has revealed that certain artifacts are older than previously believed."
Trap Type 2: Too Broad (Overgeneralization) Generalizes beyond the passage's scope. Example: If the passage is about a specific legal doctrine, a too-broad answer might say "Legal doctrines must evolve to meet changing social conditions."
Average 13.5 words — among the shortest stems because the question is inherently simple to ask. Only 68 unique stem phrasings across 263 questions — the most repetitive stem language of any type. This predictability makes Main Point questions easy to identify but not necessarily easy to answer.
Average 24.3 words — the longest of any type. Because the correct answer must capture the passage's full argument, choices are dense, multi-clause statements. Each answer choice is essentially a one-sentence summary of a possible thesis, making them long and information-dense.
Key pattern: The correct answer almost always has multiple clauses connected by "because," "by," "through," or "and." Single-clause answers are usually too narrow.
Source: PT84, Q1 The first question of the section — Main Point questions very frequently appear as Q1 for a passage. The correct answer is a multi-clause statement that captures the passage's thesis and primary supporting reasoning.
Source: PT56, Q16 For a comparative passage, the question asks about the central topic that both passages address. The correct answer describes a shared concern or question rather than a specific thesis.
Source: PT3, Q21 An early PrepTest example showing the "central thesis" phrasing variant. The correct answer must encompass the full scope of the author's argument without omitting key qualifications.
Main Point questions are rare on comparative passages because two passages rarely share a single "main point." When they appear, they typically ask about the shared central topic rather than a shared thesis.
