How do people make decisions about risky situations?
Living at the foot of one of the world’ s most active volcanoes might not appeal to you at all. But believe it or not, the area surrounding Mount Etna in Italy is packed with people. In fact, it is the most densely populated region on the whole island of Sicily. The reason is that rich volcanic soil makes the land fantastic for farming. By growing and selling a variety of crops, local people earn a good living. For them, the economic benefit they reap surpasses the risk of dying or losing property in one of the volcano’s frequent eruptions. People everywhere make decisions about risky situations this way. That is, by comparing the risks and the benefits. According to the experts, the side of the risk depends on both its probability and seriousness. Let’s take Mount Etna for example, It does erupt frequently, but those eruptions are usually minor. So the overall risk for people living nearby is relatively small. But suppose Mount Etna erupted everyday, or imagine that each eruption there kills thousands of people. If that were the case, the risk would be much larger. Indeed, the risk would be too large for many people to live with. And they would have to move away.
选项
A、One of Etna’s recent eruptions made many people move away.
B、Etna’s frequent eruptions have ruined most of the local farmland.
C、Etna’s eruptions are frequent but usually mild.
D、There are signs that Etna will erupt again in the near future.
答案
C
解析
这道题属于那种只需要对作者的倾向做出正确判断就可以做对的题。很多人选择住在活火山附近,这说明了作者的论点,所以作者肯定会说明:住在活火山周围是合乎理智的。此题的四个选项中,只有C项的事实有利于支持这一结论。
