Match the lack of subject-verb agreement solution to the correct
lack of subject-verb agreement problem: A subject that is separated
from the verb by an intervening prepositional phrase
Solutions:
a. Determine whether the noun of amount refers to one unit and is
therefore singular or whether it refers to a number of
individual units and is therefore plural.
b. Make the verb agree with the subject, which is never the
object of the preposition.
c. If the collective noun refers to a group as a whole, use a
singular verb, or if the collective noun refers to each member
of a group individually, use a plural verb.
d. Ignore the predicate nominative, and make the verb agree with
the subject of the sentence.
e. In an inverted sentence look for the subject after the verb.
Then make sure the verb agrees with the subject.
