Free ACT English: Punctuation for Clauses and Phrases Questions and Answers 2

Question 1

Which sentence correctly uses a comma with a coordinating conjunction?

Accepted Answer

The storm intensified overnight, so the evacuation order was issued at dawn.

Answer

When a coordinating conjunction (FANBOYS) joins two independent clauses, place a comma before the conjunction. "The storm intensified overnight" and "the evacuation order was issued at dawn" are both independent clauses.

Question 2

Identify the correct use of a colon: Which sentence is punctuated correctly?

Accepted Answer

The recipe requires three main ingredients: flour, eggs, and butter.

Answer

A colon correctly follows a complete independent clause to introduce a list. "The recipe requires three main ingredients" is complete. Placing a colon directly after a verb ("requires:") is incorrect.

Question 3

Which correctly punctuates an introductory adverb clause?

Accepted Answer

Although she had never skied before, she completed the advanced slope.

Answer

Introductory adverb clauses ("Although she had never skied before") are followed by a comma before the main clause. When the adverb clause comes at the end, no comma is needed.

Question 4

Which sentence uses dashes correctly to set off a parenthetical phrase?

Accepted Answer

The winning team—the one that had practiced the longest—received the trophy.

Answer

Em dashes are used in pairs to set off a nonessential parenthetical phrase. Both dashes must be present, and no comma should be used alongside a dash in this construction.

Question 5

Which correctly punctuates this sentence with a nonrestrictive appositive? "My older sister [BLANK] a marine biologist [BLANK] studies coral reef ecosystems."

Accepted Answer

"My older sister, a marine biologist, studies coral reef ecosystems."

Answer

Nonrestrictive appositives (non-essential identifying phrases) are enclosed by commas on both sides. "A marine biologist" is additional information, not essential to identify which sister.
