PG problem file Explanation
DOCUMENT();
loadMacros(
"PGstandard.pl",
"MathObjects.pl",
"draggableProof.pl",
);

The draggableProof.pl macro can be found in [OpenProblemLibrary/macros/MC/draggableProof.pl]. It is not yet part of the standard WeBWorK macros, so you have to place the file in your local macros directory for this to work.

TEXT(beginproblem());

$CorrectProof = DraggableProof([
"Jason Aubrey",
"Someone better than Jason but less than everyone else",
"John Travis"
],

[
"Don't complain about it",
"\(x^2\)"
],

SourceLabel => "Choose from these",
TargetLabel =>  "Place the people in order of increasing usefulness.",
);

Notice the format is:

[ list of correct statement in order],

[ list of incorrect statements in order],

options

Context()->texStrings;

BEGIN_TEXT

Select \{ $CorrectProof->numNeeded \} of the following.

$PAR
\{ $CorrectProof->Print \}

END_TEXT
Context()->normalStrings;

# Answer Evaluation

ANS($CorrectProof->cmp);


ENDDOCUMENT();

Notice, $CorrectProof->numNeeded returns the actual number of correct statements provided in the first list from above.
