This exercise demonstrates some other features of the JBC multiple-choice output. Note that the questions are displayed one by one. Also, the order of questions and answers is jumbled each time you load the page. Note also that this page displays a random selection of three questions out of a total of six -- the questions you see will change each time you reload the page. Finally, look out for a slightly different question type, which requires that you select ALL of the possible correct answers before checking your choice. This is new in Hot Potatoes 5.
