 Match the lack of subject-verb agreement solution to the correct

lack of subject-verb agreement problem: A subject that follows the verb


     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.
