Answer 1

Hint: An affirmative sentence contains a set of words that do not have negative words such as never, no, no, etc along with a verb or an adjective. The opposite of ‘strong’ is ‘weak’.

Complete step-by-step answer:

We know from the hint given to us that, an affirmative sentence is a group of positive words, that is, there are no negative words. A negative sentence can be converted to an affirmative sentence by the removal of the negative word(s). The negative words are removed by substituting an appropriate word that does not alter the meaning or context of the sentence. Hence, to change the negative sentence given to us in the question to an affirmative sentence, we just have to identify the negative word and substitute it with a suitable positive word.
We observe that ‘not’ is a negative word that is present in the sentence. In order to substitute it with a positive word, we must find a word that means, ‘not strong enough’, which is the opposite of being strong. From the hint given to us, we know that the opposite of strong is weak. Hence, option A is correct.
We observe that option B has a negative word ‘not’ and hence it is wrong. We also observe that option C is an affirmative sentence. However, it does not convey the same meaning as that of the sentence given to us. Hence, option C is incorrect.
Option D is incorrect as option A is the correct answer.

Note: There are different types of sentences - Imperative sentence, exclamatory sentence, declarative sentence, an interrogative sentence. These four types of sentences can either be an affirmative sentence or a negative sentence.
