gets doesn't work. I tried it at the beginning. I think the problem is
that it  Reads the *next* ``line'' from the I/O stream. (So it can't
read the string following the question mark.)


And I thought that readline was simular to gets:  Reads a line as with
 IO#gets  , but raises an EOFError on end of file.

However, it turns out ok. That is quite strange.
