!set embraced_randitem=<p> \

This field accepts the randomization by nestable curly embraces.\

<p>\

If you put several words (or groups of words), separated by commas,\

within a pair of embraces, one of the words will be randomly drawn\

at the time when the text is presented to students. This will add\

randomness to your text. <p>\

For example, if you enter the text <p>\

<tt>I will go to {Paris, New York, London} \

{tomorrow, the next week}</tt>,

<p>the result will be one of the following sentences, at random:\

<pre>\

I will go to Paris tomorrow\

I will go to New York tomorrow\

I will go to London tomorrow\

I will go to Paris the next week\

I will go to New York the next week\

I will go to London the next week\

</pre>

        <tt class="wims_code_words">randint(1..100)*10</tt>\

 <li>For a decimal number between 0 and 2:\
