Pop-Up Lists That Are Long: PG Code Snippet

This code snippet shows the PG code to create lengthy pop-up lists in a WeBWorK problem. Note that these are insertions, not a complete PG file. This code will have to be incorporated into the problem file on which you are working.

PG problem file Explanation
DOCUMENT();

loadMacros(
  "PG.pl",
  "PGstandard.pl",
  "PGcourse.pl",
  "PGchoicemacros.pl",
);

TEXT(beginproblem);

Initialization: We need to include the PGchoicemacros.pl macro file.

@questions_and_answers = (
"Larry is one of the three stooges.","True",
"\(\pi\) is rational","False",
"Gandalf is one of the three stooges.","False"
);

Set-up: An array in which questions alternate with answers. This is the only part of this example that needs to be modified. Answers may be any string.

BEGIN_TEXT

Are the following statements true or false? 
$PAR

END_TEXT

Instructions and Question for all parts: Modify the instructions if you want. You should give what the possible answers are here so that students who have a pdf hardcopy / paper-copy can work directly from it.

$n = scalar(@questions_and_answers)/2;
@shuffle = shuffle($n);
@abc = (a..z);

for $jj (0..$n-1) {
$j = $shuffle[$jj];
BEGIN_TEXT
@abc[$jj]. \{ pop_up_list(['?', 'True', 'False']) \} $SPACE 
$questions_and_answers[2*$j]
$BR$BR
END_TEXT
ANS(str_cmp($questions_and_answers[2*$j+1], filters=>["trim_whitespace","compress_whitespace"]));
}

ENDDOCUMENT(); 

Main Text and Answer Evaluation: Shuffle the order of the questions and use a for loop to generate one question and one answer evaluator for each pair in the array @questions_and_answers. You can change the pop-up list options ['?','True','False'] to any number of strings you want.
