A bad guy is playing Russian roulette with a six-shooter revolver. He puts in one bullet, spins the chambers and fires at you, but no bullet comes out. He gives you the choice of whether or not he should spin the chambers again before firing a second time. Should he spin again?

• Spin again

• Don't Spin

Answer explanation

Yes. Before he spins, there’s a one in six chance of a bullet being fired. After he spins, one of those chances has been taken away, leaving a one in five chance and making it more likely a bullet will be fired. Best to spin again

(1) Jeremy is taller than Jean: Jeremy > Jean

(2) John is shorter than Jeremy: John < Jeremy

This could be rewritten: Jeremy > John

Answer explanation

look at the water passage connections in the glasses. Water will first go in glass 1 and before it gets full, it will go to glass 3. From glass 3 it will not flow to glass 7 (as it is blocked), the same way it will try to flow to glass 6 but the opening to glass 6 is blocked, thus it will first fill glass 3 fully.

You’re at a fork in the road in which one direction leads to the City of Lies (where everyone always lies) and the other to the City of Truth (where everyone always tells the truth).
