Question

which revision correctly combines these two sentences?
jennifer went grocery shopping. she purchased supplies to make sandwiches.
○ jennifer went grocery shopping; and, she purchased supplies to make sandwiches.
○ jennifer went grocery shopping; she purchased supplies to make sandwiches.
○ jennifer went grocery shopping; and she purchased supplies to make sandwiches.
○ jennifer went grocery shopping; she purchased supplies to make sandwiches.

Explanation:

When combining two related independent clauses with a semicolon, a coordinating conjunction like "and" should not be capitalized after the semicolon, and using "and" with a semicolon is redundant here. The correct structure uses a semicolon to connect the two clauses without an extra coordinating conjunction, and the first word after the semicolon is lowercase (unless it's a proper noun).

Answer:

Jennifer went grocery shopping; she purchased supplies to make sandwiches.
