SATs Sentence Structure & Punctuation

Question 1

What is the primary purpose of punctuation in writing?

Accepted Answer

To separate words and phrases for better readability.

Answer

The primary purpose of punctuation is to clarify the meaning of written text and improve its readability. Punctuation marks like commas, periods, and question marks help to organize sentences, indicate pauses, denote sentence structure, and convey intonation, making it easier for the reader to understand the intended message without ambiguity.

Question 2

Which sentence is correctly punctuated?

Accepted Answer

She went to the store and bought apples.

Answer

This sentence is correctly punctuated because it is a simple sentence with a compound predicate ('went to the store and bought apples') that does not require any internal commas. Options A, C, and D incorrectly insert commas where no pause or separation of independent clauses/nonessential information is needed, disrupting the flow and clarity.

Question 3

When should a comma be used?

Accepted Answer

A comma is used to separate items in a list or to set off nonessential information.

Answer

Commas serve several important functions in writing, including separating three or more items in a series (e.g., 'red, white, and blue') and setting off nonessential clauses or phrases that provide additional but not crucial information (e.g., 'My brother, who lives in London, visited last week'). These uses enhance clarity and readability.

Question 4

Which of the following is a run-on sentence?

Accepted Answer

I went to the store, I bought groceries.

Answer

A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or a coordinating conjunction. In option B, 'I went to the store' and 'I bought groceries' are both complete sentences (independent clauses) incorrectly joined only by a comma, creating a comma splice, which is a type of run-on sentence.

Question 5

What is the function of a semicolon?

Accepted Answer

A semicolon is used to separate two related but independent clauses.

Answer

A semicolon acts as a bridge between two independent clauses that are closely related in meaning but could stand alone as separate sentences. It indicates a stronger pause than a comma but a weaker pause than a period, showing a connection between the ideas without using a coordinating conjunction. For example: 'The sun was setting; the sky turned a brilliant orange.'
