I just did the Quiz module that is into th System architect/Data Model spanish version, I realize it has a wrong answer, the version of the module is 8.7.
I am ataching both images that shows the right answer for the english version but it is wrong in the spanish version, in fact, I tryed all different options in spanish version and there is not possible to get a rigth answer in that question according to the system.
Please check this issue, and let me know if you need further information
Offcourse! this is the link where you can check the quiz:

Also, could you please check the options "Go to previous topic" and "Go to next topic",In spanish are switched, so to move forward it says in spanish, go to the previous topic.
