Over at The Guardian and at least some of them aren’t in fact that difficult:
8. When asked why he robbed banks, he apocryphally said, “Because that’s where the money is.” Which US bank robber gives his name to a rule of focusing on areas with likely high returns, or ruling out obvious explanations first?
Well, some on now, everyone knows that’s Willy Sutton.
9. The Oscar-nominated documentary Waste Land by Lucy Walker is about the “pickers” or “catadores” who scavange Jardim Gramacho, an enormous dump in which city?
Rio de Janeiro
Rio, obviously. The other two are Spanish speaking/influenced, and Jardim is Jardin in Spanish. It’s Portuguese for Jardim to be Jardim. So, err, D’oH!
Some of the others though are pretty tough.
