Rise 360 - ideas for even better quizzes

I am using Rise 360 to test if learners have actually captured the contents of an (externally bought) course on SQL.

Three ideas to improve the quiz features:

• When a question is multiple-choice, allow for more than one answer that is correct. This is entirely possible for many tasks. Changing the question to multiple-response is not an alternative because it requires learners to find all the right solutions, while often one is enough.
• For fill-in-the-blanks questions: whitespace should be stripped when comparing the answer to the acceptable answers (for exameple, name="Jones" is equivalent to name = "Jones"). Now we have to include many "different" acceptable answers that are basically identical. 
• For fill-in-the-blanks questions, this could be improved by having an actual "blank field" in the question that people have to fill in. Even better: more than one "blank field" could be useful:
  select * from table [where] name="Jones" [and] wage>3000;
  the [] indicate "blank fields".
