question 12 of 16
which sentence uses correct subject-verb agreement?
a. ellen, among all the students, works the hardest.
b. groups of students at the school is planning a big pep rally.
c. the airplanes at the airport is enormous.
d. the dog living in the alleys are actually quite friendly

Explanation:

• For option A: The subject is "Ellen" (singular), and the verb "works" (singular) agrees with it; the phrase "among all the students" is a prepositional phrase that does not affect subject-verb agreement.
• For option B: The subject is "Groups" (plural), but the verb "is planning" (singular) does not agree; it should be "are planning".
• For option C: The subject is "airplanes" (plural), but the verb "is" (singular) does not agree; it should be "are".
• For option D: The subject is "dog" (singular), but the verb "are" (plural) does not agree; it should be "is".

Answer:

A. Ellen, among all the students, works the hardest.
