Question

Which of the following is a run-on sentence?

Gina's alarm clock did not go off she was late to school.

Answer 1

Gina's alarm clock did not go off she was late to school."

Step-by-step explanation:

This is a run-on sentence because it is actually two independent clauses joined together without any punctuation or conjunction to separate them. One possible way to fix the sentence is to add a comma and a coordinating conjunction (such as "and" or "but") between the two clauses:

"Gina's alarm clock did not go off, and she was late to school."

Another possible way to fix the sentence is to separate the two clauses into two separate sentences:

"Gina's alarm clock did not go off. She was late to school."
