Not sure how the prompting gets involved in this problem: if you decide
to let the user choose only based on the text (i.e. "one" vs "one"),
then there's not much the prompting can do to help: the minibuffer lets
the users enter a string and that's that.
If they type "one" which one of the two should you pick?
