Hi~ When I was preparing for a test, I have got the following drill question. Would you take a look at it? (a) A : What did you have for breakfast this morning? (b) B : I had kimchi, bulgogi and a bowl of rice. (c) A : How you could eat that much so early? (d) B : Why not? I have a huge appetite. I don't have the answer key. I'm just guessing (C) could have a wrong part in itself. But that's not because I know what exactly is wrong in (C), but because in the others I can not find any wrong part. Based on my googled results, 'how you could eat that much?' was a possible sentence. So, If (C) were wrong, I am guessing it were 'so early' that could be a wrong part. But... what is wrong with the phrase? I'm confused... Please guide me. Many thanks in advance!
