Question

Which choice shows the correct use of parentheses?

A (My report card came today. I’ve been checking the mail every day.) The grades will please my parents.
B My report card came today. (I’ve been checking the mail every day.) The grades will please my parents.
C My report card came today. I’ve been checking the mail every day. (The grades will please my parents.)
D (My report card came today.) I’ve been checking the mail every day. The grades will please my parents.

Answer 1

The answer would most likely be answer B. It seems to make the most sense. The parentheses adds that he or she was checking the mail as a background check or additional 'P.S' information.

Answer 2

I believe the answer is B.
Hope that helps you.
