	4. Three hazards associated with deeper scuba diving activities include: Increased breathing resistance, possible carbon dioxide retention, shallow water blackout. Increased susceptibility to nitrogen narcosis, oxygen toxicity, increased breathing resistance. The inability to take underwater photographs, susceptibility to nitrogen narcosis, shallow water blackout. Decrease in breathing resistance, less chance of acquiring decompression sickness, increased risk for nitrogen narcosis.

	6. When surfacing an unconscious diver from depth, what is one step in the procedure recommended by NAUI?

	7. One popular and effective method NAUI recommends for towing a diver in the water while performing artificial respiration is: The modified arm lock The cross-chest carry The Pia carry/tow The do-si-do tow
