Question

Which of these sentence contains a subordinate clause?

Answer 1

The answer is A. The poem that I read in class is by Maya Angelou. (The subordinate clause is bolded.)

Subordinate means dependent - so, this clause has elements of a sentence (such as subject and predicate), but it cannot stand on its own. It only adds some information to the main clause. It always has a subordinate conjunction or a relative pronoun (which, whose, whom, etc.) which connects it to the main sentence; in this case, it is a subordinate conjunction that.
