In the following questions, a few sentences are given. Identify the sentences…

Concept

Two grammar rules govern this item. First, subject–verb agreement: the verb must match the true grammatical subject in number, even when other nouns sit between them. Second, an indefinite pronoun such as each is grammatically singular and always takes a singular verb, regardless of any plural noun that follows it in an of-phrase.

Applying it to each sentence

• “The team has worked really hard and deserves all of the praise they are receiving.” — the collective noun team is treated as a single unit, so the singular verbs has and deserves agree with it; referring to the members afterward with they is standard usage. Grammatically and contextually correct.

• “She was excited to start her new job, but her nervousness was affecting her confidence.” — a clean compound sentence: singular subjects with singular verbs (She was, nervousness was), correctly joined by but. Correct.

• “Each of the students were required to submit their projects before the deadline.” — the subject is Each (singular), not students; the of-phrase does not change the subject’s number. It therefore needs the singular was required, not were required. This sentence is grammatically incorrect.

Conclusion

The grammatically and contextually correct sentences are the team/praise sentence and the new-job/nervousness sentence; the each-of-the-students sentence fails subject–verb agreement. Hence the right set is those two correct sentences together.
