To determine the best words to fit the sentence, we need to consider the context and the grammatical structure as well as the meaning of the sentence as a whole.
The sentence is: "Seventy two year old man _ _ _ _ _ _ half his time in India and the _ _ _ _ _ _ in the US."
- The first blank requires a verb that fits the subject "Seventy two year old man" concerning the phrase "half his time in India." The subject is singular, so the correct form of the verb is "spends," which agrees with the subject. The option "spend" does not agree because it is plural.
- The second blank follows "and the," indicating a complement to "half his time in India." The word that fits here should refer to the remainder of his time. The option "rest" suitably complements "half his time" because it indicates what remains.
Thus, the correct completion of the sentence is: "Seventy two year old man spends half his time in India and the rest in the US."
Let's rule out the other options:
- "Spend, rests": The verb "spend" is plural and does not agree with the singular subject.
- "Reside, live": Neither properly fill the blanks in the sentence in terms of tense and continuity.
- "Live, remaining": "Live" lacks the notion of spending time, and "remaining" doesn't grammatically fit as a noun replacement for "rest."
Therefore, the options that fit best are "spends" and "rest."
