I would like to pose a multiple response question, in which the participant selects 4 of the 8 possible answers, and then include these 4 choices in subsequent questions. For example, if their 4 choices from the single multiple response question could be labeled 1 - 4, then later questions would ask, "How many <1> are also <2>?" or "How many <2> are also <1>?" I understand how this works if the initial question has only 1 possible answer choice, but I am unsure how to differentiate the answer choices if the initial question has multiple responses.
