98. (32682-!-item-!-188;#058&006783) (GWD 28-Q29)

Early in the twentieth century, Lake
Konfa became very polluted. Recently fish populations have recovered as release of industrial pollutants has declined and the lake’s waters have become cleaner. Fears are now being voiced that the planned construction of an oil pipeline across the lake’s bottom might revive pollution and cause the fish population to decline again. However, a technology for preventing leaks is being installed. Therefore, provided this technology is effective, those fears are groundless.

The argument depends on assuming which of the following? D C

A. Apart from development related to the pipeline, there will be no new industrial development around the lake that will create renewed pollution in its waters.

B. There is no reason to believe that the leak-preventing technology would be ineffective when installed in the pipeline in Lake
Konfa.

C. The bottom of the lake does not contain toxic remnants of earlier pollution that will be stirred into the water by pipeline construction.

D. Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause.

E. The species of fish that are present in Lake
Konfa now are the same as those that were in the lake before it was affected by pollution.

D为什么不对呢，取非的话就是如果pipeline可能产生其他污染问题的话，那么这项技术不就无效了吗，这不是削弱了结论吗？

103.
(31044-!-item-!-188;#058&005684) (GWD 6-Q28)

Which of the following most logically completes the argument below?

According to promotional material published by the city of Springfield, more tourists stay in hotels in Springfield than stay in the neighboring city of Harristown. A brochure from the largest hotel in Harristown claims that more tourists stay in that hotel than stay in the Royal Arms Hotel in Springfield. If both of these sources are accurate, however, the “Report on Tourism” for the region must be in error in stating that ____B_E_____.

A. the average length of stay is longer at the largest hotel in Harristown than it is at the Royal Arms Hotel

B. there is only one hotel in Harristown that is larger than the Royal Arms Hotel

C. more tourists stay in hotels in Harristown than stay in the Royal Arms Hotel

D. the Royal Arms Hotel is the largest hotel in Springfield

E. the Royal Arms Hotel is the only hotel in Springfield

如果Springfield只有Royal Arms一家酒店的话，他怎么可能宣称比Harristown有更多的客人呢，但文中说 If both of these sources are accurate，被绕晕了，怎么理解这道题呢？

谢谢了！！

第一题：题干是说因为没有Leak，所以没有污染。

D说Leak造成的唯一污染就是对鱼的伤害。如果取非，应该是还有别的污染也会造成伤害，而不是说Pipeline还有别的污染也会造成伤害。

第二题： S城有更多的游客呆在酒店，数目比H城多。 H城里面最大的酒店说，我们酒店入住游客的人数比S城的RM酒店入住的人数多。问下面哪一个是错的。

E：如果RM酒店是S城唯一的酒店。哪么所有S城游客都在RM酒店。因为S城游客呆在酒店的比H城多，哪么在RM酒店的游客（也就是S城的游客）就比所有在H城的游客数目还要多。这个和“H城里面最大的酒店说，我们酒店入住游客的人数比S城的RM酒店入住的人数多。”就矛盾了。

谢谢你的讲解！
我又研究了下两道题，你看是否正确

98

首先我认为D的取非应该这样理解：减少鱼的数量是管线泄露造成的唯一伤害取非后就是减少鱼的数量不是管线泄露造成的唯一伤害，那么就是管线泄露还会造成其他伤害。

但判定技术是否有效的标准是是否可以防止鱼数量的减少，所以其他伤害就无关紧要了。

103

第一句说 S比H 酒店里的游客多

第二句说 H最大的酒店比S最大的酒店里游客多

那如果两者同时成立的话，S一个酒店的劣势就必须通过多个酒店总数的优势才能弥补，而如果S只有一个酒店的话，就无法实现了.

第一题
D. Damage to the lake’s fish populations would be the only harm that a leak of oil from the pipeline would cause --> Negating this choice: leak of oil from the pipeline can cause more than one damage to the lake. So what ??? it does not weaken the argument that the techonology is inffective and that the fears is not groundless. So eliminate this
