One of the multiple choice questions in a book I was reading was as follows:
- まどを_____.
はい、おねがいします。
a) 開けましょうか
b) 開けてもいいですか
c) 開けなさい
d) 開けてくれませんか
I selected b) as the answer, but the given correct choice was a).
I can see why a) would be a more natural fit than b), but could they both be considered correct? My translation for the dialogue was essentially: 'Is it okay if I close the window?' 'Yes, thanks', but would this seem unnatural/wrong in the context?
