单项选择题

More and more people around the world are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure(冒险)—those who have climbed the highest mountains, searched into unknown parts of the world or sailed in small boats across the greatest oceans.
I would consider bungee(蹦极) jumping to be a good example of such an activity. You jump from a high place 200 meters above the ground with a rope tired to your feet. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground.
Why do people take part in such activities as these? Some people suggest that it is because life in modem societies has become safe and uninteresting. But in the past, they had to go out and hunt for food, and diseases could not easily be cured.
Nowadays, life offers little excitement(刺激). They live and work in safe conditions, they buy food in shops, and there are doctors and hospitals to look after them if they become iii. The answer for some people is to look for danger in activities such as bungee jumping.
According to the passage, more and more people around the world today ______.
A．are taking part in games that are very safe
