Choose the verb or verb phrase that correctly completes the sentence.
The entire staff at Odessa High School _______ for the Ector County Independent School District.
A.
have worked
B.

C.

D.
are working
C. works
C. works
To choose the correct verb or verb phrase that completes the sentence, we need to consider subject-verb agreement. In this sentence, the subject is "the entire staff at Odessa High School." Since "staff" is a collective noun referring to a group of people, we need to treat it as a singular noun.
With this in mind, we can eliminate options A (have worked) and D (are working) because they both use plural verb forms, which do not agree with the singular subject.
Now we are left with two options: B (work) and C (works).
To decide between them, we can look at the context of the sentence. The sentence is talking about an ongoing or general activity performed by the staff at Odessa High School. Therefore, the most appropriate verb form to use is the simple present tense.
Based on this reasoning, the correct answer is C. "The entire staff at Odessa High School works for the Ector County Independent School District."
