Require multiple correct responses to multiple choice question on Learning Assessment

Content

We have a need to require that a learner be able to respond that more than one correct response to a multiple choice question to get credit for answering the question correctly.  

For example:

• Question #1 has one correct response. The learner selects the correct response.  The learner gets credit (1 point) for the question.
• Question #2 has two correct responses. The learner must select both correct responses.  The learner gets credit (1 point) for the question.

Has anyone been able to format "Question 2" in a way to make this happen?  I'm sure it's been done, I just can't figure it out.

Thanks,
