Question

Quizplus · Accepted Answer

When a swimmer tries to use a long hose to snorkel more than a meter deep, the pressure of the water increases with depth, making it more difficult for air to enter the hose and reach the lungs. At deeper depths, the pressure of the water can be too high for the air to enter the lungs, leading to breathlessness. Hence, at the surface, the air will not freely enter the higher-pressure region in the compressed lungs, making choice D the correct answer. Choices A, B, and C are incorrect as they do not accurately describe the reason why a long hose cannot be used for deep diving.
