The theory that the impact of a giant meteorite caused the extinction of the dinosaurs is based on evidence that a cloud of dust from the impact blocked off sunlight around the globe for months, reducing temperatures and destroying the dinosaurs’ food supply.

Which of the following, if true, casts the most serious doubt on the theory above?

  • Dinosaurs are believed to have been cold-blooded and thus very sensitive to any temperature change.
  • Some dinosaurs lived in regions where their food supply was not well adapted for long periods of cold and darkness.
  • Many large animals that existed during the time of the dinosaurs and shared a common food supply with them continued to populate the Earth long after the  extinction of the dinosaurs.
  • A large volcanic explosion that strewed dust in the air and blocked out sunlight was the cause of death of animals within hundreds of miles of the eruption.
  • Many of the largest dinosaurs were herbivorous, relying exclusively on vegetation for their dietary needs.

读题:一颗巨大的陨星撞击地球引起恐龙灭绝的理论是基于一个论据:由撞击引起的灰尘连续笼罩几个月阻断了照射到地球上的太阳光,降低了温度,破坏了恐龙的食物供给

问题:下面哪一个, if true, 最反对上面的理论?

  • 恐龙被认为是冷血动物,因此对任何温度变化都非常敏感。
  • 恐龙住在他们的食物供给不能很好地适应长期寒冷和黑暗的区域。
  • 恐龙时代存在的许多大型动物与恐龙分享相同的食物来源,在恐龙灭后很久仍然继续生活在地球上。
  • 一次大型的火山爆发产生的灰尘挡住了阳光,使方圆百里内的动物灭绝了。
  • 多大型恐龙是食草型的,只能以植物为食。

The percentage of people between the ages of 18 and 24 living with their parents increased from 48 percent in 1980 to 53 percent in 1986. It can be concluded that in 1986 it was harder for people in this age group to afford to live by themselves.

 

The conclusion drawn in the passage above depends on which of the following assumptions?

  • People in this age group who could not afford to live by themselves preferred living with people their own age to living with their parents.
  •  There are people in this age group who, if they could have afforded to do so, would have chosen to live by themselves, rather than with their parents.
  •  People in this age group who lived with their parents did not make any financial contribution toward housing expenses.
  • The number of rental housing units suitable for single people dropped between 1980 and 1986.
  • There are people in this age group who although they lived with their parents at the time of survey, had previously lived alone.
