One of the recent stories indicated border agents were literally comparing answers against a Wikipedia article; if you didn't have the answer in the Wikipedia article, you were wrong.

This would be in line with, for example, how Google does early-stage screening -- non-technical people are given a sheet of questions, and if you give an answer that's not verbatim what's on the sheet you're "wrong" and "not qualified" (see http://www.gwan.com/blog/20160405.html).
