Question 25

He is the best substitution for the underlined words.

In the sentence, "The boy watched the lights in the house go off," the word "he" directly relates to the subject of the sentence, making it the most suitable substitution for the underlined words.

A) him

The word "him" is an object pronoun and does not fit the context as a substitution for the subject of the sentence. It would incorrectly imply that "him" is the one performing the action, whereas the sentence requires a subject pronoun.

B) his

"His" is a possessive pronoun, indicating ownership or association. It does not serve as a suitable substitution for the underlined words, which need a pronoun that functions as the subject of the sentence.

C) they

"They" is a plural pronoun, which does not match the singular subject "the boy." Using "they" would incorrectly imply that multiple subjects are involved, thus failing to accurately substitute for the underlined words.

D) he

"He" is a subject pronoun that appropriately substitutes for "the boy" in the sentence. It maintains the singular form and keeps the meaning intact, correctly indicating that the boy is the one watching the lights.

Conclusion

The substitution "he" is definitively correct as it aligns with the subject of the sentence, maintaining clarity and grammatical accuracy. All other options fail to serve as proper substitutes due to their roles as object pronouns, possessive forms, or plural references, which do not fit the context provided.
