CoStudy's SAT Reading and Writing bank holds 315 items. Every multiple-choice question carries a written rationale explaining why the correct answer is correct and why each distractor is tempting but wrong.
A sample of 12 multiple-choice questions from the bank, with the full rationale shown.
SAT R&W: A text says, 'Despite initial skepticism, the researchers ultimately accepted the hypothesis.' Which BEST captures the structure?
Answer: D — Reversal — initial doubt followed by acceptance; SAT loves 'despite/although' patterns of shifting position
Contrast + shift transitions. 'Despite' signals concession followed by main idea. SAT R&W tests recognizing this rhetorical move. Spot the signal words: although, despite, even though, yet, nevertheless.
Which corrects the dangling modifier? 'Walking through the park, the trees seemed taller than ever.'
Answer: C — Walking through the park, I noticed the trees seemed taller than ever.
The original implies trees were walking. The introductory participial phrase 'Walking through the park' must modify the actual walker. B correctly attaches it to 'I.' This is a frequent SAT R&W modifier test.
A pronoun reference is unclear when:
Answer: C — The pronoun could refer to more than one antecedent in the same sentence or paragraph
C) Ambiguous antecedent rule. A/B/D) Each does not cause ambiguity per se.
Which choice correctly uses an apostrophe? 'The _____ research papers were due Friday.'
Answer: C — students'
'Students'' is plural possessive — multiple students owning research papers. 'Student's' is singular possessive (one student). 'Students' is plural without possession. 'Students's' is incorrect.
Identify the verb tense error: 'By the time the storm arrived, the team _____ already evacuated the building.'
Answer: B — had
Past perfect ('had evacuated') describes an action completed BEFORE another past event ('the storm arrived'). The past-perfect/past-simple sequence is essential. A is present perfect; C is plural present; D is wrong tense.
Inferring an author's purpose involves asking:
Answer: D — Why the author wrote this text — to inform, persuade, explain, entertain, or analyze
D) Standard purpose categories. A–C) Biographical or publication facts, not purpose.
SAT Writing: Which is correct? 'Each of the dogs ___ a bone.'
Answer: D — has (singular 'each' takes singular verb)
'Each,' 'every,' 'either,' 'neither,' 'one,' 'someone,' 'anyone' all take SINGULAR verbs, even when followed by 'of the [plural].' Test classic.
SAT Writing: 'The cat that I adopted ___ very playful.' Verb?
Answer: B — is (singular subject 'cat')
Subject-verb agreement with relative clauses. 'That I adopted' modifies 'cat' (singular). Main clause needs singular verb.
A primary source in a research-style passage is best described as:
Answer: B — Original material from the time period — letters, diaries, photographs, government records, eyewitness accounts
B) Standard definition. A/C/D) Each is typically secondary or tertiary.
Which is the MOST effective opening sentence for a paragraph that will discuss three causes of the 1929 stock market crash?
Answer: C — The 1929 stock market crash resulted from three interrelated factors: rampant speculation, weak banking regulation, and consumer overleverage.
C previews the structure and content (three specific factors). A is vague evaluation; B is uselessly broad; D is irrelevant. Effective topic sentences are specific and forecast paragraph organization.
SAT Writing: Best use of a semicolon:
Answer: B — She arrived early; she unpacked quickly. (joins two INDEPENDENT clauses, no conjunction)
Semicolon: joins two related independent clauses without conjunction. A is wrong (no conjunction needed after ;). C is wrong (semicolon doesn't connect to fragment). D is comma splice. Common SAT/PSAT/ACT punctuation trap.
A semicolon may be used to:
Answer: D — Join two closely related independent clauses, or separate items in a list when items themselves contain commas
D) Standard uses of the semicolon. A/B/C) Each misstates the rule.
6 sample cards from the 250 in the bank.
Ethos vs pathos vs logos?
Ethos: credibility. Pathos: emotion. Logos: logic.
When use past perfect?
When showing one past event happened before another. 'By the time I arrived, she had left.'
What is the main argument of an opinion piece?
Position the author wants you to accept. Usually in thesis or repeated.
What's a logical fallacy?
Flaw in reasoning that weakens an argument.
Good vs well?
Good (adjective): describes noun. Well (adverb): describes verb. Exception: 'feel well' = healthy.
Transition for sequence?
First, next, then, finally, subsequently.

Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.

Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
This bank is written against the College Board's published exam material. Check the SAT test specifications for the current outline, fees and eligibility rules — those change, and the certifying body is the only authority on them. CoStudy is not affiliated with the College Board.
