Question

read the sentence. the squirrel who ran in circles around the circumference of the tree chattered 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 use of commas for non - restrictive clauses. The phrase "who ran in circles around the circumference of the tree" is a non - restrictive clause (it provides extra information about the squirrel, not essential for identifying the squirrel). In such cases, we should set off the clause with commas.

• Option 1: "The squirrel, who ran in circles around the circumference of the tree, chattered angrily at the curious cat." Here, the non - restrictive clause is properly set off with commas.
• Option 2: There are no commas around the non - restrictive clause, which is incorrect.
• Option 3: The comma after "angrily" is misplaced and disrupts the sentence structure.
• Option 4: The comma after "angrily" is misplaced and the non - restrictive clause is not properly punctuated.

Answer:

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