How do you use the "~ㄴ/는다" form in a question? I was watching a video and I heard this: "4년 어디 간다?" I'm confused, because I thought that ~ㄴ/는다 was only used for statements, but here it's in a question. If context is important: in the video, an idol group is playing a game where they have to answer questions about one of the members. One of them says that he'll get every question right because he's been friends with that member for four years. However, he ends up getting the question wrong, and another member shouts "4년 어디 간다?" https://www.youtube.com/watch?v=_B9_rNlGdoE&feature=youtu.be&t=167
