Better put questions in a global constant.  Otherwise you'll always
recreate the array on each invocation of testwrite_using_array().

There's no point in chompig the same string twice.

You don't need array_counter because the array knows its size.

You rather want:

user_responses << xx

Cleaner, easier and faster.

You don't write to the file - as a consequence there is nothing in there.
:-)

File.open(filename, "a") {|io| io.puts answers}
