The mentioned site is fun (though I don't see the quoted questions, but different ones).
Reading through the various answers cures you from ever thinking these kind of AI can give logical answers. The 'I bought 10 apples ...etc' question had a massive amount of totally wrong answers, the 'five planets closest to the sun' question shows that many computers can't even count to five, and a disturbingly low amount of them knows that the Earth's 'distanceToEarth' is zero.
