I scored 87%, mostly by trying to tell apart scanned photographs from images created directly on the computer.
Something interesting happened at number 2, though. I am not much of an art knower, but the name "Mondrian" somehow popped into my head when I saw the image. I don't think I have heard that name uttered since high school 15 years ago, but something must have stuck. However, the question then is, is this a real Mondrian or a fake one? It would be fairly easy to cook up something that looks sufficiently Mondrian-like to fool me, particularly if one had a few samples of actual Mondrian available as a style reference.
The point is, I think, that it is not too clear to a taker of this test whether the task is to distinguish between masterpieces and parodies of particular masterpieces, or to distinguish between masterpieces and parodies of the more general idea of nonfigurative art. It becomes a guess-the-tester's-intentions game just as much as an experiment in recognizing actual excellence.
In the end I tagged #2 as real only due to the signs of brushwork at its lower left, end I didn't think that so much effort would be invested in a casual fakery for a web quiz.
