Question

He makes a noise (change into negative )

Answer 1

Explanation:

After changing the affirmative sentence to negative, it becomes

He does not make noise

Affirmative sentences can be easy converted to negative sentences by addition of do not or does not depending upon the sense of the sentence.

But here we have also changed "a noise" to just "noise" because it is in more specific term and "a noise" is used in common sentences or where we need to address the crowd.

Answer 2

Here is the correct answer:

He does not make a noise.

Explanation

The tense of the given sentence is Simple Present. In order to convert it into negative sentence, we have to use the helping verb + not. The helping verb of this tense is do/does not. Since the subject is singular, we use ‘does not’.
