Pronoun-antecedent agreement

14a. You may rent a movie or a video game for just one night if they are new.

14b. You may rent a movie or a video game for just one night if it is new.

my answer is b.

I think this is one is also right, but, please make sure you check all of these with your teacher.

You're both right again. :-)

Your answer is correct! In this case, the correct sentence is 14b, "You may rent a movie or a video game for just one night if it is new."

The reason for this is pronoun-antecedent agreement. An antecedent is a word or phrase that a pronoun refers back to, and it is essential for the pronoun to agree with its antecedent in number and gender.

In sentence 14a, the pronoun "they" is used to refer back to "a movie or a video game." However, "a movie or a video game" is singular, so the pronoun should also be singular. Therefore, the correct pronoun to use in this case is "it," as shown in sentence 14b.

Remember, when determining pronoun-antecedent agreement, pay close attention to the number of the antecedent. If it is singular, the pronoun should be singular as well, and if it is plural, the pronoun should be plural.
