Identify the type of sentence. The officer ran into the house where the fugitive was hidden.

Complex sentence

Explanation:

This sentence is not simple as it has an independent clause followed by a dependent clause. The officer ran into the house (by itself is a simple sentence) but when we pair it with the sentence that follows it becomes a complex sentence because "where the fugitive was hidden." is a dependent on the first part because without first part we wouldn't know where the fugitive was hidden (thus the latter is dependent). Therefore, this is complex sentence.

Complex Sentence

Explanation:

Compound sentences are two independent clauses joined together by a comma, semicolon, or conjunction.

Complex sentences have at least one independent clause and one dependent clause.

Since

The officer ran into the house ...

is an independent clause and

the fugitive was hidden

is a dependent clause, this is a complex sentence.
