Multiple (pop-up) graded questions on a single slide

Hi, Larissa,

With regular and freeform graded questions, only 1 question can be on a slide. The question and responses are on the base, and the feedback is shown on the Correct and Incorrect layers. 

It's hard to tell without seeing the source file of the project you linked to, but I'd guess that it uses custom variables, conditions, and states to create a question layer for each hazard. Or they might use multiple layers for each hazard (e.g., start, correct, and incorrect).
