Final answer:
The sentence should be revised by inserting commas around “which the teacher assigned” to correctly punctuate the nonrestrictive element.
Step-by-step explanation:
- To correctly revise the punctuation in the sentence, we need to insert commas around the phrase “which the teacher assigned” because it is a nonrestrictive element that adds extra information about the homework but is not necessary to the main point of the sentence.
- The revised sentence should read: “The entire first period class agreed that yesterday’s algebra homework, which the teacher assigned, was a really fun challenge.”
Nonrestrictive elements, which can also be called nonessential elements, should be set off by commas, whereas restrictive elements, which are essential to the meaning of the sentence, do not require commas.
