Explanations

With \explanation the author can define a feedback that the user gets if an answer wasn't (completely) correct.

Usage: \explanation[optional condition]{text}.

Within the explanation text variables can be used the same way as in question tasks and answer texts. Explanations on question level are displayed if one or more than one answers wasn't correct. On answer level explanations are displayed if the specific answer wasn't correct. The author can optionally decide if an explanation is displayed only if certain mistakes were made or if a random variable has a specific value.

With \showExplanation{always} the author can define, that an explanations is always displayed - even if the user's answer was correct.
