About This Quiz

Which is as it should be -- scuba diving is considered an extreme sport, and it does cause about 13 deaths per 100,000 divers. And yet, this fatality rate is on par with jogging. So is scuba truly dangerous? Or just misunderstood?

However, few people actually use the capitals, just like few people remember that the word "SCUBA" doesn't refer primarily to a form of diving, but to the equipment itself. The gear that a diver takes down is called a "scuba set," and its primary components are the tank of compressed air, the hoses and the mouthpiece through which the diver breathes.
