Question

Simple or compound: the students cleaned up after they finished the experiment

Answer 1

Answer: It is a simple sentence.

Explanation:

Compound sentences contain a FANBOYS (for, and, nor, but, or, yet, so) coordinating conjunction following a comma. Since this sentence does not contain a FANBOYS conjunction after a comma, it is a simple sentence.

example compound sentence:

I was hungry, so I made myself a sandwich.

example simple sentence:

I made myself a sandwich because I was hungry.
