Puzzler of the week

[Scott MacLean]

This week's puzzler:

It was a dark and stormy night. You're on Isle Nubar off Costa Rica. You're in your Nissan Pathfinder and you're being pursued by Tyrannosaurus Rex.

Your only hope is to get off the island. Otherwise, you're going to be passing through the digestive system of said Rex. You have to make it to the dock because that's where your little boat is. If you don't make it to the dock -- you're done for!

The pterodactyls are circling overhead. You're driving along, and you come to a fork in the road. One road takes you to certain death because you don't know where that goes. The other one takes you to the dock where your little boat awaits.

Sitting at the fork are two guys. Now, on this island there are either liars or truth tellers. You know one road leads to death; the other to the dock. You can ask one question of either one of the two guys. One of these guys is a liar and one of them is a truth teller.

You have no way of identifying them. Is there one question you can ask of either of these guys that will unquestionablyget you on the right road to the dock?

Last week's puzzler:

In 1982, John is 12 years old. 1987 John is seven years old. How can that be? Hint: his name probably wasn't John.

Last week's puzzler answer:

The answer was that it was BC. 1982 BC, and 1987 BC.
