Using a "Select answer" question for a quiz, respondents can only select one answer. I have some questions that have multiple correct answers, but after making a single selection, the respondent can not make an additional selection. This is not a big deal; even selecting one of multiple correct responses supports learning, and the facilitator can flag there are multiple correct answers after the response time is closed. However, it would be nice if a setting were added to "Select multiple options", as is possible with the non-quiz multiple-choice questions.
