Question 80

Was

In this sentence, the correct form is "was," which agrees with the singular subject "the professor," even when preceded by the plural subject "the students." This construction requires the verb to be in the singular form.

A) Was

This option is correct because it matches the singular subject "the professor" in the sentence. The phrase "Not only the students but also" indicates that the focus is on "the professor" as the main subject, which necessitates a singular verb.

B) Were

This option is incorrect because "were" is a plural verb form, which does not agree with the singular noun "the professor." Although "the students" is plural, the structure of the sentence places emphasis on "the professor," requiring the singular verb "was."

C) Are

This option is incorrect as "are" is also a plural verb form. The sentence requires a past tense verb, and using "are" would not adhere to the temporal context suggested by "stunned by the test results," which implies a completed action.

D) Be

This option is incorrect because "be" is an infinitive form of the verb and does not fit grammatically in this context. The sentence requires a past tense verb to convey that both subjects were affected by the test results.

Conclusion

The correct answer "was" effectively reflects the grammatical structure of the sentence, ensuring subject-verb agreement with the singular noun "the professor." All other options fail to maintain this agreement or do not fit the tense required for the context, thereby making them unsuitable choices.
