"Are you hungry?"
Why is "배가고픕니다" incorrect? I wrote this as my answer and was marked as incorrect/wrong.
The "-다" at the end implies a statement, which would say "You are hungry." But "-까" implies a question, as in "Are you hungry?"
Because it's a question not a statement. For a question, sentence usually ends with 까.
Same but i think its because of formality or its a question so it ends with that
