TIP: Create a "Pick One" Question with Multiple Correct Answers

A "pick one" question allows only one correct answer. Well, that's the point of "pick one."

But what if there's more than one right answer to a question, and you only want the user to choose one? Or what if you want the user to identify something in an image, and the image includes more than one of those objects? 

The attached Storyline file shows how to set up a "pick one" question that does allow more than one correct answer. 

The trick is having the on-slide selections control the actual "pick one" buttons, which are off the slide. 

This is just one example of how useful off-slide items can be!
