Question

Read the sentence.

The entire first period class agreed that yesterday’s algebra homework which the teacher assigned was a really fun challenge.

Insert commas around “yesterday’s algebra homework” because it is a restrictive element.
Insert a comma after “the entire first period class” because it is a restrictive element.
Insert commas around “which the teacher assigned” because it is a nonrestrictive element.
Insert a comma before “a really fun challenge” because it is a nonrestrictive element.
