The test is questionable. I've never been to Paris, haven't seen many pictures of it, except for Eiffel tower. I only looked at text found on the pictures (i.e. "Public transportation of Barcelona" ;) and some other clues. With this simple logic reasoning, I got 81%. If you compare this with guys living in Paris who report 90% here, it does not make much sense.
Yeah they should have removed the texts, but as a long time parisian I can recognise Paris with only a gutter or a window frame, it would have made the test more meaningfull.
