There is a new question type which can be used in 1.5 in CVS "contrib/quiz_renderedmatch_qtype"
This is a new question type that allows for several additions
and relaxations of the existing matching format.
- as few as one subquestion
- many incorrect subanswers (distractors) and one correct answer per question
- rendered html for subanswer and subquestions, this allows
for TeX or images etc. to be included in the quiz.
enjoy!
