Answer:
The correct answer is Complex sentence.
Step-by-step explanation:
The sentence given has two ideas:
- Patricia plans to attend a Bible seminary.
- She graduates.
The first one is an independent clause, since it can stand alone as a complete sentence. The second one is a dependent clause, because it can't stand alone as a complete sentence and is being used to provide extra information about the main idea.
The subordinating conjunction "after" is used to join this two clauses and show a relationship of time, meaning that the main action will be completed by the moment marked by the condition.
Patricia plans to attend a Bible seminary after she graduates.
This is structure is known as a complex sentence.
