Hi, Ahmed.A.A—The answer choice is intended to be a truncated question: "[Do you] want some?" But the question should be preceded by a period or a dash:
- I want to get some juice. Want some?
- I want to get some juice—want some?
I agree with your answer, but can't this be an exclamatory question (since it invites the hearer's agreement to something on which the speaker has
strong feelings)? ( (Quirk, page 825)
