The verb in the sentence with a subordinate clause must
agree with the subject of the whole sentence, not with a noun in the subordinate
clause. Subordinate clauses can begin with the words that, which, who,
and whom.
Not:The children who live in
that house is a terror! But:The children who live in
that house are a terror!
Not:San Francisco, which has
many lovely neighborhoods, are exciting to visit. But:San Francisco, which
has many lovely neighborhoods, is exciting to visit.
