MCQ slides with images (back to basics)

Intro

Recently another request on the Adobe forums appeared about quiz slides:

"....insert images as the Options/Answers in the Multiple Choice Questions"

I answered within a short time showing a screenshot of such a question slide, quickly designed:

It is not really that difficult, but reminded me of the fact that many newbies have not really an idea about the way quiz slides are created. Although I have already published many articles about quizzes (see overview),  want to explain how I realized that quiz slides in minutes.

I would have posted this in the community as another Tweak post, but since 3 posts I entered since 2nd of July are still not approved, and i wanted to provide a clear answer to the OP on the Adobe forums, will only post in my personal blog.

Quizzing Master slides editing

All question slides are based on a dedicated master slide. One unique master slide is used in any theme for MCQ (one answer and multiple answers), True/false, Fill-in-the-Blank and Sequence questions. Typical for those master slides is that all the items are embedded, they have no individual timeline. You'll find more information in my other blogs. The most important part for this use case is the so-called Answer area:

That particular item is the container for the Question answers. It is however NOT possible to edit the individual question answer captions. 

Even with the default setting in Preferences which prefers Smart Shapes over Text Captions, all items on quiz slides are always captions! Question slides need a long due refurbishing, shape buttons as quiz buttons are also not allowed. 

To make place for images, you need to make the Answer area as big as possible. Move the buttons to the bottom, make the feedback messages as small as possible and move them downwards as well. Move the captions at the top as high as possible (Type of question, Progress indicator in this case as well, Question). Now you'll be able to increase the size of the Answer area:

Question slide editing

Only on quiz slides it is possible to edit the individual answers. I increased the number of answers to 4, and rearranged the answer captions to make them as big as possible. I took out the numbering and the text caption placeholder. You see the four answer captions inside of the (red) answer are:.

As most embedded items on the quiz slides, those answer captions have functionality built in. I would like to compare those captions with 'hotspots'. When you click a caption, the radiobutton will be selected. For a MCQ with multiple correct answers, it will be a checkbox that is selected. 

All embedded objects are always on top of the stack (z-order). If you insert an image in the area defined by the answer caption, it will be below the 'hotspot' and the functionality will be preserved. That is the only trick I used to have the resulting question slide with the maps of some European countries (SVGs). Since it is an original quiz slide, all functionality (Retake, Review) can be used. 

The workflow is also valid for quiz slides in question pools.
