"Can you give me a bowl?"
The sentence does not have to include the subject in order for it to be complete, as long as the meaning can be deciphered or known to the listeners.
However, both forms are correct. :)
Yes, but in this case it seems that including 你 causes the answer to be marked wrong. I just provided this as my answer, and it was wrong:
It's not wrong (even if Duo does not accept it). Most of the cases 你 can be omitted; if you don't omit it, it also would not sound very unnatural (unless you never omit any subject, then we would feel your speech strange).
It is not the most usual and "correct" order but it happens people say like that, with a pause 给我一个碗，可以吗？. It shows a little hesitation.
is absolutely correct and should be accepted. Reported.
