Question

4
angie agreed to help matt repair his car engine, so he promised to tutor her in calculus, history, and physics they are going to work together all weekend.
what change, if any, should be made to this sentence to correct an error in punctuation?
a. add a semicolon after physics
b. remove the comma after history
c. no change
d. remove the comma after engine

Explanation:

To determine the correct punctuation change, we analyze each option:

• Option B: The comma after "history" is part of a series (calculus, history, and physics), and the Oxford comma (the comma before "and") is acceptable here, so removing the comma after "history" is incorrect.
• Option D: The comma after "engine" is used to separate two independent clauses joined by "so" (a conjunction), and it is correctly placed, so removing it is wrong.
• Option C: The two independent clauses "Angie agreed...physics" and "they are...weekend" are not joined by a conjunction or appropriate punctuation. A semicolon is needed to separate them, so "NO CHANGE" is incorrect.
• Option A: The sentence has two independent clauses. The first ends at "physics", and the second starts with "they are...". A semicolon should be added after "physics" to properly separate the two independent clauses.

Answer:

A. add a semicolon after physics
