听力原文：Man: I love deep-sea diving. I go at least once every summer. The deeper you go,the quieter everything becomes, until finally all you can hear is the sound of your own heartbeat. It's my way of getting away from it all, finding some peace for once. I spent my honeymoon diving, although my wife's not so keen, and it's not something we always do together. I don't need company necessarily, and I'm not looking for some incredible adventure. I did, however', once join some guys in a cage off Florida, searching for the great white shark. If sharks stop moving, they die. That sounds like me back home.

You hear a man talking about deep-sea diving. Why does he like the sport？

A．It suits his sociable nature.

B．It contrasts with his normal lifestyle.

C．It fulfils his need for a challenge in life.
