Why isn't "iya atau nngak?" accepted as correct?
I know that grammatically it should have a question mark, but duolingo doesn't usually care about punctuation
Would “tak” work here?
Tak was given as a choice, but marked incorrect. I'm going to report it.
Can you use "bukan" in any circumstances?
Bukan is used if there is another answer to the question. Like "Ini bukan restoran, ini hotel"
