I changed the question for copyright purposes:
Professor John denied a request to allow his students to take the test home instead of to take the test in the class.
(A) to allow his students to take the test home instead of to take the test in the class
(B) that would have allowed his students to take the test homey instead of taking the test to
(C) under which his students to take the test home instead of confining them in
(D) that would allow his students to take the test home the end of each day rather than to
(E) to allow his students to take the test rather than be confined to
E is the correct answer. I am not really seeing what this sentence is trying to test. Parallelism. If so why isn't D parrallel. In addition is Instead of and rather than a valid split in this question?
