Answer: This is the FIRST, SECOND, THIRD... one. Question: ?

Question

How do you ask the question in English to get the above answer?

In English is there a question word that specifically asks the position of something in order? For example, I ask a question and you say "This is the THIRD one." What is that question? Is there such a question word?
For example when I ask "Who?" you may say "Mary," when I ask "What?" you may say "Apple." I hope my question is is clear this time. Thank you.

Sorry this is the third time I revise my question. In English is there a question word that specifically asks where an item is located in an order? Is there such a question word that when I say it you answer "This is the THIRD( or FIRST, SECOND, or FIFTH, etc.) one." What is that question? Is there such a question word? Obviously not, because people do not understand what I am trying to get at.
Could anybody who speaks any foreign language please help?
Look: For example when I ask "Who?" you answer "Mary," when I ask "What?" you answer "Apple." So when I ask "Bla?" you answer "Third/Fourth/Fifth/etc." What is that word? If you don't have it you don't have it. I just hope somebody understands my question. Thank you.

Answer 1

OK, I get it.
I think you can use "which".
For example ... WHICH person will be next at the check out counter.
It would be the SECOND person in line.

WHICH horses will win money for the bettors. The FIRST, SECOND and THIRD across the finish line.
