Question

read the sentence.
the squirrel who ran in circles around the circumference of the tree challenged angrily at the curious cat.
which correctly revises the sentence?
○ the squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat.
○ the squirrel who ran in circles around the circumference of the tree, chattered angrily at the curious cat.
○ the squirrel, who ran in circles around the circumference of the tree chattered angrily at the curious cat.
○ the squirrel who ran in circles around the circumference of the tree chattered angrily, at the curious cat.

Explanation:

To determine the correct revision, we analyze the sentence structure. The phrase "who ran in circles around the circumference of the tree" is a non - restrictive clause (it provides additional information about the squirrel) and should be set off by commas. Also, the verb "chattered" is the main verb of the sentence, and the prepositional phrase "at the curious cat" should be correctly attached. Let's analyze each option:

• Option 1: "The squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat." This option correctly uses commas to set off the non - restrictive clause and has the correct verb - object relationship with "chattered angrily at the curious cat".
• Option 2: The comma after "tree" is incorrect as it disrupts the flow of the non - restrictive clause and the main clause relationship. Also, the way "chattered angrily at the" is presented is awkward.
• Option 3: The semicolon is incorrect here as a semicolon is used to separate two independent clauses, and "who ran in circles around the circumference of the tree" is a dependent clause.
• Option 4: The comma after "angrily" is incorrect and disrupts the prepositional phrase "at the curious cat".

Answer:

A. The squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat.
