Question

Which sentence contains a correctly punctuated nonrestrictive modifier? Jake, who is twenty-seven, is studying to be a yoga teacher. Jake who is, twenty-seven, is studying to be a yoga teacher. Jake who is twenty-seven is, studying to be, a yoga teacher. Jake, who is twenty-seven is, studying to be a yoga teacher.

Answer 1

Jake, who is twenty-seven, is studying to be a yoga teacher. 

Answer 2

The correct answer is A. Jake, who is twenty-seven, is studying to be a yoga teacher.

A nonrestrictive modifier is a word or a phrase that is separated from the rest of the sentence using commas. This is because it is a nonessential element - this means that if it were eliminated from the sentence, it would still make perfect sense. You need to place the entire dependent clause in commas - who is twenty-seven.
