Which of these sentence contains a subordinate clause? a) the poem that i read in class is by maya angelou. b) the maple tree in the back yard grew to be quite tall. c) working the early morning shift can be very exhausting. d) the red cardinal stood out against the white snow and the black barn.

The correct answer is option A) The poem that I read in class is by Maya Angelou.

Explanation:

Let's start by clarifying what it is a subordinate clause.

A subordinate clause is that part of a sentence that if we wrote alone would not make sense. It is something we use to link an idea into a sentence.

All subordinate clauses must have a subject and a verb.

To make it clearer let's look at the example:

The poem that I read in class is by Maya Angelou.

In this case, "that I read" is a relative pronoun (which is part of the subordinate clauses) and which serves to link the subject with an idea: that I read in class.

If we only wrote a sentence that says "that I read in class is by Maya Angelou" the sentence would not make sense and something would be missing.

Therefore, the correct answer is option A.
