multiple required answers in MC question

I have searched and browsed and haven't found a definitive answer, so please excuse this post if it is a repeat:

In 1.9, is there a way to have a multiple choice question in which the student gets 0 points unless they have selected all the required responses?  For example:

Apples are:

1. red
2. green
3. yellow
4. blue

100% credit if 1,2, and 3 are marked, and any other combination gets 0%.

I can't seem to find a way to do this in multiple choice or cloze questions, but it seems like a pretty common way of creating/grading a question.

 

Thanks!

See Question Type: All-or-nothing multiple choice.

From its doc:

The all-or-nothing multiple choice question is a version of the core multi-answer multiple choice question with modified grading.

In an all-or-nothing multiple choice question, a respondent can choose one or more answers. If the chosen answers correspond exactly to the correct choices defined in the question, the respondent gets 100%. If he/she chooses any incorrect choices or does not select all of the correct choices, the grade is 0%.
