9to4

What is 9to4?

9 real photos, 1 question: "Which 4 of these castles are in Spain?" or "Which 4 peaks are over 5,000 m?" Pick the right 4. The catch: the wrong ones are close calls, like castles from neighbouring countries. Castles, aircraft, vehicles, peaks and islands, all real and credited to their photographers on Wikimedia Commons.
