I have a question about a sentence below.
we expect about 50% of registered voters to vote in the election.
Is a PP(in the election) a subject complement(is it possible?) or a modifier?
If it is a modifier, does it modify a verb(vote)?
While searching out it, I happened upon a sentence and relating explanation
He was selected (as) chairman.
In this case, was isn’t a linking verb. However, some answered the question. "Chairman is a subject complement."
So I can’t understand a subject complement.
