Question

read the following sentence:
noah attempted to perform his first (and what he hoped would not be his last) magic trick for his little brother
what is the purpose of the parentheses in the sentence?
○ to indicate an omission
○ to indicate an interruption
○ to set off extra information
○ to set off necessary information

Explanation:

In the sentence, the parentheses enclose the phrase "and what he hoped would not be his last", which provides extra information about the magic trick (that it's his first and he hopes not last). Omissions are indicated by ellipses, interruptions by em dashes or other marks, and necessary info wouldn't be in parentheses. So the purpose is to set off extra info.

Answer:

to set off extra information
