Lately, i have come to believe the quality of DocCD does not reflect what to
expect in the Lab exam. It's the only way I can keep my sanity, and stay
optimistic about our chances of passing it.
In case we do encounter a case like this, then i guess the proctor is the
only way to resolve the ambiguity. Assumptions are too risky.
