Which sentence uses a verb that agrees with its subject?
A. Brazil, of all the South American countries, are the only one where Portuguese is the main language.
B. A tornado during the late summer months is typical for many midwestern states.
C. The nurses on duty at the hospital appears very tired. D. The lettuce in those salads are probably not organic.



Answer :

The answer is (B) A tornado during the late summer months is typical for many midwestern states.

The answer is not A) because the verb are is plural but the subject Brazil is singular.

The answer is not C) because Since it says nurses, it should be appear not appears.

The answer is not D) because Since it already says those, it should be salad not salads.
