The last question, under the heading “Two-Part Analysis”, at the end of this NYT article (from July 2011) on the new GMAT seems to be deliberately worded in a way that forces one to read and think very carefully.

It takes a while to even process the question as it’s asked! I’m assuming that was intentional.

I’m curious how “they” intended people to solve this. Exclude impossible answers until only one is still Included? I guess so.
