And you know what? I'll tell you why people get this wrong. It's because their brains turn off. They say "omg microscopes scary! big block of text!" and guess at answers instead of actually bothering to try and read the text. That's one reason why they get poor scores at reading comprehension: a lack of reading with intent to comprehend. Heck, if they're pressed for time and the guessing-wrong penalty is low enough, it's an entirely rational response.

The fact that the journalist is that dense is mostly a symptom of "oh hey I've found an argument against standardized testing to fit my preexisting conceptions of the matter! Screw reading it, it looks complicated, I'll just use it to justify things." Same basic problem.
