The original took only one and gave one answer (and errored out when
the user asked for more), but this one loops.  I can see either way
is OK and do not think of a good reason to favor one over the other;
unless there is a strong reason why you need this extended behaviour
that allows users to ask multiple questions, I'd say we should keep
the original behaviour.
