Question

Change the negative sentence into an affirmative sentence without changing the meaning:
I do not believe you.

• A. I disbelieve you.
• B. I cannot believe you.
• C. I do not disbelieve you.
• D. You are not worthy of my belief.

Answer 1

The correct option is A I disbelieve you.

A negative sentence is the opposite of an affirmative (positive sentence) and expresses an opposing idea. It contains a negative word like 'no', 'not', 'never' etc along with the main verb or words like 'nobody', 'no one', etc. An affirmative (or positive) sentence does not contain any such negative word.

When we change a negative sentence by removing the negative word, we must take care that the verb is modified by using a word opposite in meaning.

Option A: This is an affirmative sentence which does not contain any negative word. The verb, 'believe' has been changed to its opposite word, 'disbelieve'. This sentence communicates the same meaning as the original sentence. Hence, this option is correct.

Options B, C and D are incorrect as these sentences contain the negative words, ''cannot', /'not'. Hence these are all negative sentences.
