Why? they think we are dumb here in canada??!@!

Either that or the Americans are too dumb to pass the test.

the test is a hack of Canada's legal code by the promotions business. Canadian anti-gambling law makes it illegal to sell chances to win a prize, so promoters always offer a free method of entering each contest, and task every winner with a skill-testing question. By doing the latter, they argue, the game is no longer one merely of chance but a contest requiring some skill.

Thanks for the explanation.

I've wondered this myself, since I see it on many contests. I was curious.

I gave up entering sweepstakes a long time ago. I was only reading it, because I was waiting for the software to install and the box was the only thing around to read.
