（1）Jennifer: Video rental outlets in Centerville togetherhandled 10,000 fewer video rentals in 1994 than in 1993. The decline in rentals was probably duealmost entirely to the February 1994 opening of Videorama, thefirst and only video rental outlet in the area that, in addition to rentingvideos, also sold them cheaply.
Brad: There must be another explanation: as you yourself said, the decline was on theorder of 10,000 rentals. Yet Videorama soldonly 4,000 videos in 1994.
Whichof the following, if true, would most seriously weaken the force of theobjection that Brad presents to Jennifer's explanation? 暂时未弄明白为什么选E不选A？
(A)In 1994 Videoramarented out more videos than it sold.
(B)In 1994 two new outlets that rent but that do not sell videos opened inCenterville.
(C)Most of the video rental outlets in Centerville rent videos at a discount oncertain nights of the week.
(D)People often buy videos of movies that they have previously seen in a theater.
(E)People who own videos frequently loan them to their friends.
（2） Whichof the following most logically completes the argument?
UnitedStates manufacturers currently produce most of the world's solar-powergenerators--most of which are exported to Europe. However, European manufacturers are emergingand probably will ultimately capture much of the European market. The United States government is fundinginitiatives intended to encourage use of solar power within the UnitedStates. If these initiatives succeed inincreasing the demand for solar-power generators in the United States, UnitedStates manufacturers will probably maintain significant production levels,since __________.
未弄明白为什么选C不选E，因为E中如果现在的MARKET很LIMITED的话，那么它将来应该有很大的发展空间啊？
(A)some United States manufacturers have been substantially increasing theiroutput over the last several years
(B)the efficiency of solar-power generators in converting energy from the Sun intoelectric power is not improving as fast as it once did
(C)just as European manufacturers enjoy certain competitive advantages in Europe,so do United States manufacturers in the United States
(D)European governments are currently undertaking initiatives to stimulate the useof solar power within Europe
(E)the current market for solar-power generators in the United States is verylimited
此外还有一个狒狒的：
Ordinary mountain sickness, a common conditionamong mountain climbers, and one from which most people can recover, is causedby the characteristic shortage of oxygen in the atmosphere at high altitudes.Cerebral edema, a rarer disruption of blood circulation in the brain thatquickly becomes life-threatening if not correctly treated from its onset, canalso be caused by a shortage of oxygen. Since the symptoms of cerebral edemaresemble those of ordinary mountain sickness, cerebral edema is especiallydangerous at high altitudes.
Whichone of the following is an assumption on which the argument depends?
(A)The treatment for ordinary mountain sickness differs from the treatment forcerebral edema.
(B)Cerebral edema can cause those who suffer from it to slip into a coma within afew hours.
(C)Unlike cerebral edema, ordinary mountain sickness involves no disruption ofblood circulation in the brain.
(D)Shortage of oxygen at extremely high altitude is likely to affect thinkingprocesses and cause errors of judgment.
(E)Most people who suffer from ordinary mountain sickness recover without anyspecial treatment.
这一道题为什么要选A呢？
多谢各位的帮忙。
