SAT Reading & Writing: Standard English Conventions (Drill 14) is a Reading & Writing practice drill covering Standard English Conventions. It contains 5 original questions created by Brian Stewart, a Barron's test prep author with over 20 years of tutoring experience.
These five questions cover paired commas around an interrupting phrase, the colon before a list, subject-verb agreement across intervening nouns, plural possessive apostrophes, and the comma after an introductory clause.
Question 1. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: The phrase "an external support that carries the outward thrust of a vault down to the ground" renames the buttress and interrupts the sentence, so it sits inside a matched pair of commas; the closing comma after "ground" is already printed, so the opening mark is a comma too (C). (A) a dash would need a dash to close it, not a comma. (B) a colon can't fence an interrupter, and "The flying buttress" is not a complete clause before it. (D) a semicolon needs a full sentence on each side.
Question 2. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: Everything before the blank is a complete clause, and the examples that follow spell out what observers see, so a colon introduces them (A). (B) a comma can't set up a list this way after a full clause. (C) a semicolon needs a full sentence after it, not a string of examples. (D) "and" just tacks one more item onto the clause and blurs the list structure.
Question 3. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: Strip out the modifiers and the subject is just "Kintsugi," which is singular, so the verb is the singular "turns" (C). (A) "turn" is pulled toward the plural "ceramics" inside the modifier rather than the singular subject. (B) "have turned" and (D) "are turning" both use plural verb forms that don't match a singular subject.
Question 4. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: Merchants and money changers are two separate plural groups, and each owns its own calculations, so both words are plural possessives: "merchants' and money changers'" (D). (A) uses singular possessives, but each names a whole group. (B) drops the apostrophes the possession needs. (C) leaves "money changer's" singular while making "merchants'" plural.
Question 5. Which choice completes the text so that it conforms to the conventions of Standard English?
Explanation: "Because no single butterfly lives long enough to complete the round trip" is a dependent clause, so it joins the main clause with a comma (B). (A) a semicolon can't follow a dependent clause. (C) a period cuts the "Because" clause off as a fragment. (D) running the two parts together with no mark leaves the sentence fused.
