It is not proper grammar to end a question with another question. A question should end with a question mark, not another question.
When merging a question with alternates into another question, the alternates of the merged question are merged into the alternates of the primary question.
I can only answer your question with another question: is Gaahl capable of loving another human being?
An "alternate" is another phrasing of the question, or the same question with spelling mistakes. These are "merged" into another question, so that if someone asks the question with one spelling or phrasing, they will be shown the main question and answer.
you can also "respond" or "reply" to a question

I'll answer your question with another question. Can you spell vehicles?
I think another scientific question
It means that the question you asked was already asked by another user, and was made into an alternate wording of another, similarly worded question. Generally, this happens when a question is merged into another question that means the same thing, so that there aren't two questions asking the same thing.
