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.

幾十年前，地球是宇宙射擊場的一個靶子，容易受到未知的隨機暴力事件的攻擊。1991年
美國國會要求美國國家航空航天局調查大型撞擊對地球造成的危害。指揮這項研究的團隊
通過詳細的分析得出這樣一個結論︰隕石撞擊確實是危險的。盡管大型撞擊發生的風險依
然存在，但是謹慎的研究這門也認為這種風險的出現幾率非常小
這是黃金閱讀中的一篇
答案給1
實在看不出為什麼...
