Most of the committee members _____ in favour of the ______ of a new dam in that village.

The correct answer is: B. are, proposing

The sentence is in the present tense, so the verb “to be” must be in the present tense as well. The verb “to propose” means to suggest or put forward an idea. In this case, the committee members are suggesting or putting forward the idea of building a new dam in the village.

The other options are incorrect for the following reasons:

• Option A: The verb “was” is in the past tense, which does not agree with the present tense of the rest of the sentence.
• Option C: The verb “were” is also in the past tense, and the noun “construction” is singular, which does not agree with the plural subject “committee members.”
• Option D: The verb “not” is a negative word, which does not make sense in the context of the sentence. The committee members are not suggesting that the dam should not be built, they are suggesting that it should be built.
• Option E: The verb “still” is an adverb, which does not make sense in the context of the sentence. The committee members are not suggesting that the dam is still being built, they are suggesting that it should be built.
