大神帮忙解答两道GRE逻辑阅读题 选什么以及为什么~

1. The damage that trucks do to highways escalatesdramatically with the weight borne per axle. New regulations increase themaximum permitted vehicle weight; these regulations will therefore allow ontothe highway trucks capable of doing even more damage than those currentlypermitted.

The major weakness of the passage above is that theargument
A. Fails to establish that the level of damage done bytrucks is a serious problem.
B. Omits evidence about one of the two relevant factors.
C. Ignores the possibility that careful driving canlessen damage to highways.
D. Presumes that trucks are the only vehicles capable ofcausing substantial damage to highways.
E. Presumes thatsomething is bound to happen just because it is allowed to happen.

2. The Rivera Art Museum recently began chargingadmission. The resulting decline in visitors has been far larger than at otherlocal museums, which have also begun charging admission. The magnitude of thedecline might be due to the Rivera's location near government offices. Becausean admission charge is most discouraging to those who plan a short visit, it islikely that government workers who formerly made brief visits during lunchtimeand after work now do not.

Which of the following, if true, most seriouslyundermines the proposed explanation？
A. The fee for admission to the Rivera is no larger thanthat charged by other museums.
B. The Rivera does not keep track of how long individualvisitors stay in the museum.
C. The decline in visitor to the Rivera has been nogreater on workdays than it has been on nonworking days.
D. The museum with the smallest decline in visitors isthe most popular with visitors from other countries.
E. In the period between the announcement that therewould be an admissions charge and its actual introduction, there was anincrease in visitors at the Rivera

Answer 1

第一题应该选B哈，抱歉抱歉，注意文中第一句with the weight borne per axle，这里有两个因素，weight和axle，而后面只说了weight增加，没有说axle怎么样，所以忽视了两个因素中的一个。

第二题选C，如果说工作日与否，游客人数的减少都差不多的话，那就和政府人员没有关系
这是标答

Answer 2

1题还有个值得考虑的是E选项哈
假设允许发生的事注定会发生

这里的注定会发生的事即指题目的"will allow onto the highway trucks capable of doing more damage"
如果the weight borne per axle的确是增加了的话，那么允许更多的承重的确将会导致造成更多破坏，因为这是第一句的数学关系提供的信息
所以在the weight borne per axle增加的前提下，允许发生的事确实将会发生。所以E不属于题目的假设，而是事实，所以不选

Answer 3

D
这题说卡车重，导致路面损坏，新规定允许卡车更重，所以结论是路面会更加被损坏。
错误是导致路面损坏的原因不仅有卡车重的原因，还可能有其他原因。
C
这道说博物馆收费之后人数减少，而且比其他博物馆减少得更多，为啥？也许这个博物馆挨着办公室，推测在那上班的人现在不去博物馆了。
问哪一个最削弱，那得跟上班有关，工作日跟周末减少的人一样多，那就不是worker的原因。
一起学习吧，可能不对，加油！
