SAT Sentence Structure & Punctuation

Question 1

Which of the following sentences is correctly punctuated?

Accepted Answer

The dog barked loudly.

Answer

The sentence "The dog barked loudly" is correctly punctuated because "loudly" is an adverb modifying the verb "barked" and does not require a comma. Commas are not used to separate a verb from its adverb when the adverb directly follows the verb and is essential to the meaning, nor are they used between a subject and its verb in such a simple sentence structure.

Question 2

What is the correct way to punctuate this sentence? He loves to read books play video games and eat pizza.

Accepted Answer

He loves to read books, play video games, and eat pizza.

Answer

When listing three or more items in a series, commas are used to separate each item. The Oxford comma (the comma before "and" in a list) is generally preferred in academic and formal writing to prevent ambiguity and ensure clarity. Therefore, "He loves to read books, play video games, and eat pizza" correctly applies this rule.

Question 3

Which sentence contains a correctly placed semicolon?

Accepted Answer

She went to the store; she bought groceries.

Answer

A semicolon is correctly used to join two independent clauses that are closely related in meaning but could stand alone as separate sentences. In option C, "She went to the store" and "she bought groceries" are both complete thoughts. The semicolon effectively connects them to show their close relationship without using a coordinating conjunction.

Question 4

Which sentence uses a comma correctly?

Accepted Answer

After the game, we went to eat dinner.

Answer

A comma is correctly used after an introductory phrase or clause that precedes the main independent clause of a sentence. In option A, "After the game" is an introductory prepositional phrase. The comma clearly separates it from the main part of the sentence, "we went to eat dinner," improving readability.

Question 5

Which of the following sentences is grammatically correct?

Accepted Answer

The books on the shelf are new.

Answer

This sentence demonstrates correct subject-verb agreement. The subject of the sentence is "books," which is plural, not "shelf." Therefore, the plural verb "are" must be used to agree with the plural subject "books," making "The books on the shelf are new" grammatically correct.
