!set embraced_randitem=<p> \
This field accepts the randomization by nestable curly embraces:\
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\
