Question

read the sentence.
marlena, who enjoys many different subjects, likes history and geography the best.
which part of the sentence is the nonrestrictive modifier?
likes history and geography the best
and geography the best
who enjoys many different subjects
marlena

Explanation:

A nonrestrictive modifier adds extra, non-essential information to a sentence and is set off by commas. It does not change the core meaning of the sentence if removed. In the given sentence, removing "who enjoys many different subjects" leaves the core meaning ("Marlena likes history and geography the best") intact, and it is separated by commas. The other options are either the main subject or the main predicate of the sentence.

Answer:

who enjoys many different subjects
