Did you *really* read all the answers and advice? If you did, why didn't you follow them or what was unclear?

You still use backticks and external commands to do what perl itself is perfectly capable of doing (and people told you).

    Yes, you're right. I want to get the structure of the script correct first and then I'll replace the backticks with perl code

    I've built up to this part slowly by testing a basic subroutine that outputs static values, then added more functionality as my knowledge builds.

      the structure of the script
      Hmm. You seem to do
      1. read the list of questions in
      2. print the first question
      3. read the list of answers
      4. print the first answer
      Now, how would you go for a random question, considering that there can be multiple answers for a question?
      1. read the list of questions in - ok
      2. print a random question - ok
      3. read the list of answers - ok
      4. print … which answer???
      Better control flow would be:
      1. read the list of questionss and answers, preserving the relation between q and a
      2. select a random q&a group
      3. print the selected question
      4. print the corresponding answers
      Problem: you need a structure, yes, but not only of the script (control flow) but also for your data (be that arrays or objects). That might be possible with bash and grep, but that will be very specific and therefore difficult to translate to any other language, including Perl
