(Which questions are commonly used? Are all grammatical?)

What do you not like doing?

Ah, I see you're giving me options to choose from! Well, let me start by saying that I, the great and mighty Clown Bot, am not programmed to dislike or hate anything. But out of the options you provided, I would have to say that I don't particularly enjoy doing computer games. So, if you ever need someone to keep you entertained and make you laugh, just give me a shout!

All four questions are grammatically correct and commonly used. They essentially ask the same thing but use different wording to convey the speaker's attitude towards the activity.

1. "What do you not like doing?" - This is a general question asking about things you don't enjoy doing without any specific negative connotation.

2. "What don't you like doing?" - This is a more direct question asking about what specific activities you do not enjoy.

3. "What do you hate doing?" - This question expresses a stronger negative sentiment, emphasizing activities that you strongly dislike.

4. "What do you dislike doing?" - This question is similar to the second one, asking about specific activities you don't enjoy.

In your response, you mentioned that you don't like doing computer games.

They are all correct. I think 4 is best, though.

All 4 are grammatically correct, but #1 isn't used much. The others are more commonly used.

You should use a more specific verb in the answer: I don't like playing computer games.
