It was tricky work to get the 'htm' version and the 'jcw' version to look the same, but I have done it. Hopefully, you can't tell the difference between them now
For your information, the difference in appearance was caused by newlines in the reading. Generally, these are converted to <br> tags, so that they appear as newlines in the browser. However, your reading had a <table> in it, and there were newlines between the tags for cells (<td>) and rows (<tr>). I had to refine the HotPot module scripts, so that only newlines outside <table> tags were converted.
If you have any other quizzes that behave strangely, please let me know!
all the best
