GRE阅读高频机经原文及题目：恐龙灭绝和行星撞地球

恐龙灭绝和行星撞地球(逻辑)

Iridium, a hard, whitish metal similar to platinum, is extremely

rare on Earth. Extremely high concentrations of iridium on Earth

result from only two scenarios: massive volcanic eruptions that

release iridium from deep within the Earth and meteorites that

shower down on Earth from space. When scientists found

concentrations of iridium 30 times higher than normal in rock

stratum from 65 million years ago, they concluded that a massive

meteor or comet hit the Earth and caused the massive extinction

of the dinosaurs.

Which of the following, if true, most strongly supports the

scientist’s conclusion?

A. Volcanoes massive enough to generate high

concentrations of iridium are very rare.

B. Massive volcanic eruptions occurred frequently 80 million

years ago.

C. Most scientists support the hypothesis that a cosmic

impact wiped out the dinosaurs.

D. The massive extinction that occurred 70 million years ago

killed not only the dinosaurs but also 70 percent of all life on

Earth.

E. A comet struck the earth some 120 million years ago, but

no widespread extinction occurred.
