Remember that hints and explanations will only be displayed if the SHOW_HINTS parameter is included in the applet tag on your web page.
The separator line identifies the text to follow:
(Why "why"? "Why" is shorter to type than "Explanation", that's why...)
Following the separator line, your hint or explanation can consist of one-or-more lines of text. Like any other text in the AppletQuiz applet, you do not need to worry about formatting the text into separate lines - AppletQuiz will format it to fit the hint/explanation window for you. If you do include line breaks and/or blank lines in your text, the AppletQuiz applet will honor them, however.
There is no difference, as far as AppletQuiz is concerned, between a hint and an explanation - both are typed and formatted exactly the same way. The hint is available before the student chooses an answer for a question, and the explanation is available after the correct answer has been displayed.
In the following question file, the first question has both a hint and an explanation, while the second question has only a hint (no explanation), and the third question has neither a hint nor an explanation.
\TITLE Hint & Why? Demo \TF A T This is a true/false question. \HINT This is a hint (of sorts). \WHY This is an explanation, though, perhaps not a very good one. \TF A T This question has a hint, but no explanation. \H And this is it! \TF A T This question has neither a hint nor an explanation.
