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 statements 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.
