thinking like a 13-year old with Asperger syndrome

I've been pressing C. to 'think like a 13-year old with Asperger syndrome,' as LexAequitas advises. Today C. got the hardest question in a section right because he thought like a 13-year old with Asperger syndrome, and I missed the same item because I didn't.

from the Blue Book, Sample Test 3, Section 7, page 541

Both authors agree on which of the following points?

(A) A maritime environment would have presented unique challenges to early Americans.
(B) The first Americans most likely subsisted on mastodons and other big game.
(C) Overland travel to the New World would have been difficult during the most recent ice age.
(D) It may never be definitively determined when America was initially settled.
(E) The Clovis people were most likely the first Americans.

The two arguably correct answers are C and D. I chose D after C. said he was choosing D. We compare notes sometimes when we're doing sample tests. Bad habit.

Then C. went back and changed his answer to D on grounds that in fact neither author had actually said, explicitly, that it may never be definitively determined when America was initially settled.

Never break the Asperger rule.
