I tried this option first:
 if (reply != 'yes' && reply != 'no')

Which now if response is anything but those two answers brings up the
"please answer yes or no..."

However, I've added the return reply , and if response is anything but
yes or no, it notifies responder but still moves on to the next
question.  The case statement is preferable but it hasn't been
introduced yet to my learning material.

def ask question
    reply = nil
      while (not reply)
          puts question
          reply = gets.chomp.downcase

      if (reply !='yes' && reply != 'no' )
          puts ' Please answer "yes" or "no".'


      elsif reply == 'yes'
          reply = true
      else reply == 'no'
          reply = false
          return reply
        end

    end
end
