Simple response to あなたはばんごはんを食べて、なにをしますか


> あなたは ばんごはんを 食べて、なにを しますか。

This seems to be saying "what do you do while eating dinner?" How to reply "I
just eat"? Does it make sense to say nothing?

It seems to be asking "What do you do after eating dinner?" ( _lit._ "You eat
dinner, and what do you do?")... though it would be more natural to say it as
「あなたはばんごはんを｛食べて **から** /食べ **たあと** ｝、なにをしますか？」 or 「あなたはばんごはん **のあと**
、なにをしますか？」

"What do you do while eating dinner?" would be more like 「あなたはばんごはんを食べ **ながら**
、なにをしますか？」

> How to reply "I just eat"?

"I just eat" would be like 「食べるだけです。」 but I don't think it answers the
question. You could instead reply with 「[some activity you usually do after
dinner]+(し)ます。」, as in:

> 「テレビをみます。」 I watch TV.  
>  「ゲームをします。」 I play games.  
>  「ねます。」 I go to bed.  
>  「シャワーをあびて、ねます。」 I take a shower and go to bed.
