Configuring Interactions

When test-takers have a single choice

You can use the same technique as in the previous chapter to create interactions which allow just one single answer. In the example below, we have exchanged Denmark for France so that the only correct choice is Austria. All you have to do is setting the Max value on Allowed Choices to 1. You will notice that this turns the checkboxes into radio buttons, which means the choices are now mutually exclusive.
