Answer:
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 <u>we use to link an idea into a sentence.
</u>
All subordinate clauses <u>must have a subject and a verb.
</u>
To make it clearer let's look at the example:
<em>The poem </em><em>that I read</em><em> in class is by Maya Angelou</em>.
In this case, "that I read" is a relative pronoun (which is part of the subordinate clauses) and which <u>serves to link the subject with an idea:</u> that I read in class.
If we only wrote a sentence that says <em>"that I read in class is by Maya Angelou" </em>the sentence would not make sense and something would be missing.
Therefore, the correct answer is option A.
