   B<Answerable>
   
   The answerable method differs from the completable method in its handling of problem parts
   for which feedback on correctness is suppressed, but the student still has tries left, and
   the problem part is not past due, (i.e., the student could submit a different answer if
   he/she so chose). For that case completable will return 0, whereas answerable will return 1.
