Question 1

In sentence 1, the word "knew" is functioning as a verb.

The word "knew" in sentence 1 serves as a verb, indicating an action performed by the subject. This aligns with the grammatical function of "knew," which is the past tense of "know," thus confirming its role as a verb.

A) In sentence 1, the word "knew" is functioning as an adverb.

This option is incorrect because "knew" does not describe or modify a verb, adjective, or another adverb, which is the function of an adverb. Instead, it denotes a state of knowing, characteristic of a verb.

B) In sentence 1, the word "knew" is functioning as a verb.

This statement is accurate as "knew" is the past tense of "know," categorizing it as a verb that expresses an action or state of the subject in the sentence. Verbs convey an action or occurrence, making this the correct identification.

C) In sentence 3, the word "really" is functioning as an adjective.

This option is incorrect because "really" does not modify a noun in the sentence, which is the primary role of an adjective. Instead, "really" serves to intensify an adjective or another adverb, suggesting it functions differently.

D) In sentence 3, the word "really" is functioning as a noun.

This option is also incorrect since "really" does not represent a person, place, thing, or idea, which are the characteristics of a noun. It serves to modify or enhance the meaning of another word, not to stand alone as a noun.

Conclusion

The correct answer is B, as "knew" is clearly identified as a verb in its contextual use, while all other options misidentify the grammatical roles of the words discussed. Understanding the function of words in sentences is essential for accurate grammatical analysis, and in this case, the only accurate identification is that of "knew" as a verb.
