Answer:
The antecedent of the pronoun 'she' is Mrs. Wilton
Explanation:
To answer this question we need to understand what an antecedent of a pronoun means.
A pronoun antecedent is a word that comes before a pronoun to which the pronoun refers.
How to define the pronoun antecedent?
The word "antecedent" means something that precedes something else. In our case, it is the word that a pronoun refers back to. Since the pronoun replaces the noun, it agrees in number (if the antecedent, or word that comes before, is singular, then the pronoun must be singular too).
As for our sentence - After she went to the market, Mrs. Wilton had to pick up her daughter at dance class.
We see it is a complex sentence, it has one independent clause (Mrs. Wilton had to pick up her daughter at dance class) and one dependent clause (After she went to the market). Although the dependent clause is written before the main clause, it is still considered to follow the main one. What does this mean? We understand from a sentence that Mrs. Wilton has to pick up her daughter..., Mrs. Wilton is a subject here, the main doer of an action. Then we see a clause that explains when she can do it - after she (Mrs. Wilton) went to the market. So, the antecedent of the pronoun 'she' is Mrs. Wilton as 'she' refers to her.
I hope it helped you :)
