#: The back-reference in the Response model is a Query named 'answers'

#: For Questions that are not multiple-choice (see the choice_ids and

#: contain a single string that is a free-form text answer.
#:
#: For Questions that *are* multiple-choice, this list will contain one
#: or more short, plain-text, "link_id-like" strings representing the
#: "encoded" answer choices (see the choice_ids property in
#: soc.models.question.Question). For such multiple-choice Questions,
#: how many strings are stored depends on the max_answers property of
#: the soc.models.question.Question entity for which this is an Answer.
#:
#: If question.is_optional is True, 'answers' may even be None or an
#: empty list if no answers were provided.
#:
#: Answers can be indexed, filtered, and sorted by this list, but only in
#: the way that query operators work with a db.ListProperty.
