To ask a question, you can use the ㅂ니까 ending with a question mark. The rules on how it all connects are the same as above.
- 학생이 도서관에 많습니까?
- Are there a lot of students in the library?
- (student library-in many?)
- 지금 무엇을 합니까?
- What are you doing?
- (now what do?)
Or you can insert the honorific marker (시).
- 지금 무엇을 하십니까?
- What are you doing?
- (now what do?)
- 어디 삽니까?
- Where do you live?
- (where live?)
