1、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 has 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
正确选项：
E
证明这种做法并不能减少对太空望远镜观测的影响。
逐项分析：
A、许多不工作的人造卫星仍然在轨道上运转数年。正是因为此，我们才要对其进行爆破。
B、对于已经停止工作的卫星，在轨道上对其进行修复的成本很高。无关项。
C、以前没有人工爆破卫星的先例。无关项。以前没有不代表以后没有。
D、想让太空望远镜观测无干扰的唯一办法是使用发射到离地球很远的轨道中的太空望远镜。无关项。
E、正确选项。对人造卫星进行爆破会产生很多的小碎片，而地球周围过多的小碎片会给观测带来不好的影响。
2、Suncorp, a new corporation with limited funds, has been clearing large sections of the tropical Amazon forest for cattle ranching. This practice continues even though greater profits can be made from rubber tapping, which does not destroy the forest, than from cattle ranching, which does destroy the forest.
Which of the following, if true, most helps to explain why Suncorp has been pursuing the less profitable of the two economic activities mentioned above?
(A) The soil of the Amazon forest is very rich in nutrients that are important in the development of grazing lands.
(B) Cattle-ranching operations that are located in tropical climates are more profitable than cattle-ranching operations that are located in cold-weather climates.
(C) In certain districts, profits made from cattle ranching are more heavily taxed than profits made from any other industry.
(D) Some of the cattle that are raised on land cleared in the Amazon are killed by wildcats.
(E) The amount of money required to begin a rubber-tapping operation is twice as high as the amount needed to begin a cattle ranch.
正确选项：
E
找到放牧业比橡胶业更好的地方。
逐项分析：
A、A森林的土壤营养素十分丰富，而这种营养素对蓄牧地发展非常重要。无比较，排除。
B、畜牧业在不同地区之间的比较，排除。
C、在一些地方，蓄牧业的利润比其他产业的利润会被征收更多的税。无关项。
D、这和S公司的选择是反的，如果此陈述为真，会削弱S公司的选择。
E、正确选项，说明了本地区畜牧业比橡胶业的优势。
