Unclear question. However, I inferred the actual question to be;
What is the antecedent of the pronoun? <em>Mrs. Edwards always writes her comments at the end of the essays.</em>
Answer:
<u>Mrs. Edwards</u>
<u>Explanation:</u>
Yes, often in the English language the antecedent of a pronoun refers to a word that will be replaced by a pronoun. But remember a pronoun simply refers to a word used instead of a noun.
From the sentence;
<em>"Mrs. Edwards"</em> = a noun (the antecedent)
"her" = a pronoun.
A is wrong because "Wendys'" should be "Wendy's", because the possessive isn't plural.
C is wrong because "Its" should be "It's", because "It's" is a contraction for "It is."
D is wrong because the apostrophe should be after "judges", not "statements." Statements do not own anything, but the judges own the statements.
B is the correct answer.
Assateague is a large island off the coast of Virginia, it is inhabited by wild ponies.
What? This doesn't make sense..
