一道托福阅读题求解释,
Paragraph 7:【Earth is a target in a cosmic shooting gallery,subject to random violent events that were unsuspected a few decades ago.】 In 1991 the United States Congress asked NASA to investigate the hazard posed today by large impacts on Earth.The group conducting the study concluded from a detailed analysis that impacts from meteorites can indeed be hazardous.Although there is always some risk that a large impact could occur,careful study shows that this risk is quite small.
11.Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?Incorrect choices change the meaning in important ways or leave out essential information.
Until recently,nobody realized that Earth is exposed to unpredictable violent impacts from space.
In the last few decades,the risk of a random violent impact from space has increased.
Since most violent events on Earth occur randomly,nobody can predict when or where they will happen.
A few decades ago,Earth became the target of random violent events originating in outer space.
2,和3可以排除,然后我选的4,希望有详细的思路说明~

你是没读懂原文的意思.
原文是说,random violent events 并没有被人发现（suspected）,直到a few decades ago.
也就是说几十年前,人们还不知道地球会遭受一些无法预测的星体的撞击.
而不是说,几十年前,地球才开始有这个危险.
这个危险是一直存在的,只是几十年前人们才意识到.
懂了吗
这种题只要你读懂意思,然后把主干都抓出来,就选得对了
