The given sentence is an example of a complex sentence.
Explanation:
Complex sentences are sentences that contain an independent clause and at least one dependent clause. The sentence <em>When Sara turned her homework in, she forgot to put her name on it</em> can be divided into two clauses:
- Independent clause - <em>She forgot to put her name on it.</em>
- Dependent clause - <em>When Sara turned her homework in.</em>
Conjoined (compound) sentences contain two or more independent clauses connected by coordinating conjunctions (for, and, nor, but, or, yet, so). For example:<em> They borrowed books from the library but didn’t read them.</em>
A simple sentence is a sentence consisting of only one independent clause. For example: She likes to read.
