Noun / Pronoun + 呢？
呢 (ne) is a handy little particle. After a noun or pronoun, it bounces the question back: 我叫马克，你呢？ = “I'm Marc, and you?”
With no context, X呢？ often means “Where is X?”: 我的书呢？ = “Where's my book?”
呢 can also soften a question that already has a question word: 他是哪国人呢？ (“So which country is he from?”).
Later you'll see another use: 呢 at the end of a sentence for an action in progress (我在吃饭呢).
