Nice job Ruth, I'm turning your PR into a draft so that Jesus knows it's not ready to be merged yet.

I'm trying not to touch level 13 and up now, so we don't get any merge conflicts, so I've got a small job for you. I have found a weird mistake in level 7. Somehow I have put the adventure 'quizmaster' in level 7, where it definitely doesn't belong because we don't use <> yet (i think because we were planning on using the words greater than and less than, but we're gonna let that ship sail) anyway... I think it's better to change it on your PR, so level 13+ won't get any merge conflicts, hopefully...

Could you:

• Change quizmaster from level 7 to level 13 in the english file.
• Make the content level 13 proof (so the right syntax in the example code).
• Check whether all the keywords are marked as such with the curly braces, I recieved a comment that this was not the case in this adventure.
• update the Dutch quizmaster adventure as well
• Remove the quizmaster adventure from the other languages (because fixing the syntax in other languages is probably too hard, unless you feel upto it).
• Add Quizmaster to level 13 in hedy_content.py and remove it from level 7

Let me know if you have any questions!

Done it!

The quizmaster was only there in English actually. So I added it in Dutch and the rest can be done by translators.
