One or more responses to the Question, if the corresponding question_type is SingleChoice or MultiChoice; should be an improper subset of the responses available for the question.
An improper subset is identical to the set of which it is a subset. So, if I read this correctly, it says that the array of answers submitted with (e.g.,) the Person Signup Helper should include ALL possible responses, not just the responses chosen by the person.
Assuming we actually want the person's responses, and not the set of all possible responses, the word "improper" should be removed.
