Quiz: Multiple correct answers and only click on one

You need a pick one, and some triggers.  Each correct answer is covered by a filled object that has no outline, and is set to very high transparency. Each spot has a trigger to select the correct answer for the Pick One interaction. To keep the hand from showing over the correct spots, the whole image is covered with a filled, high transparency object under the correct answers. That gives your learners a hand anywhere on the image, (if it has a trigger attached to it.) The trigger attached to it sets the incorrect answer when clicked.
