Answers:a.
Bill and Emily are going to the movies. [Because there are two subjects (Bill and Emily) you
need a plural verb – are.
b. Among the many reasons he enjoys making chocolate truffles is the opportunity to lick all the
mixing bowls. [Remember to spot what the subject is not -- for example, it is neither reasons
nor truffles; it is the singular noun opportunity. Therefore, we need a singular verb -- is.]
c. The company announced today that it filed an emergency statement with the Securities and
Exchange Commission. [Company is a singular entity.]
d. Each of these cars has mechanical problems. [The pronoun each always takes a singular verb.]
e. A number of my friends were at the party. [A number refers a plural amount.]
f. At the opera, one of the singers fell off the stage and broke his ribs. [One is the subject of the
sentence, so its accompanying pronoun also must be singular. In this example, a male broke his
ribs.]
g. Three-fourths of the grain shipment has been damaged. [See “The Always Singular Subject”:
Definable units of money, measurement, time, organization, food and medical problems always
take singular verbs.”]
h. None of your theories makes sense. [See “The Singular or Plural Subject”: In this sentence,
none means “not one” theory.]
i. The United Auto Workers took its election defeat in stride. [United Auto Workers is a singular
entity.]
j. She is the only one of the writers who is eager to hold a public reading. [She (singular) is the
subject of the sentence, so its accompanying verb also must be singular.]
k. I understood most of Helen's arguments, but I was not persuaded by them. [Helen’s arguments
(plural) is the subject of the sentence, not Helen; the accompanying pronoun must also be
plural.]
l. A politician should always be attentive to his or her constituents' concerns. [A politician is the
subject, but the sentence does not specify the politician’s gender. If using his or her feels a bit
clumsy, you may wish to rewrite it as such: Politicians should always be attentive to their
constituents’ concerns.]
