  7(Z). Which of the following most logically completes the argument below?

  Although the number of large artificial satellites orbiting the Earth is small compared to the number of small pieces of debris in orbit, the large satellites interfere more seriously with telescope observations because of the strong reflections they produce. Because many of those large satellites have ceased to function, the proposal recently been made to eliminate interference from nonfunctioning satellites by exploding them in space. This proposal, however, is ill conceived, since .

  A. many nonfunctioning satellites remain in orbit for years

  B. for satellites that have ceased to function, repairing them while they are in orbit would be prohibitively expensive

  C. there are no known previous instances of satellites’ having been exploded on purpose

  D. the only way to make telescope observations without any interference from debris in orbit is to use telescopes launched into extremely high orbits around the Earth

  E. a greatly increased number of small particles in Earth’s orbit would result in a blanket of reflections that would make certain valuable telescope observations impossible

  8.(Z)Which of the following most logically completes the passage?

  A certain tropical island received food donations in the form of powdered milk for distribution to its poorest residents, who were thought to be malnourished. Subsequently, the rate of liver cancers among those islanders increased sharply. The donated milk was probably to blame: recent laboratory research on rats has shown that rats briefly exposed to the substances aflatoxin tend to develop liver cancer when fed casein, a milk protein. This result is relevant because .

  A. in the tropics, peanuts, a staple of these island residents, support a mold growth that produces aflatoxin.

  B. the liver is more sensitive to carcinogens, of which aflatoxin may be one, than most other bodily organs.

  C. casein is not the only protein contained in milk.

  D. powdered milk is the most appropriate form in which to send milk to a tropical destination.

  E. the people who were given the donated milk had been screened for their ability to digest milk.

  正确答案:E A
