涛涛GWD31-4 中的几道CR，请指教

Editorial:  The roof of Northtown Council’s equipment-storage building collapsed under the weight of last week’s heavy snowfall.  The building was constructed recently and met local building-safety codes in every particular, except that the nails used for attaching roof supports to the building’s columns were of a smaller size than the codes specify for this purpose.  Clearly, this collapse exemplifies how even a single, apparently insignificant, departure from safety standards can have severe consequences.

Which of the following, if true, most strongly supports the editorial’s argument?

1. The only other buildings whose roofs collapsed from the weight of the snowfall were older buildings constructed according to less exacting standards than those in the safety codes.
2. Because of the particular location of the equipment-storage building, the weight of snow on its roof was greater than the maximum weight allowed for in the safety codes.
3. Because the equipment-storage building was not intended for human occupation, some safety-code provisions that would have applied to an office building did not apply to it.
4. The columns of the building were no stronger than the building-safety codes required for such a building.
5. Because the equipment-storage building was where the council kept snow-removal equipment, the building was almost completely empty when the roof collapsed.

Q27:

In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat.  Having noted the manatee hunters’ expert knowledge of manatees’ habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.  Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees’ survival.

Which of the following, if true, raises the most serious doubt about the plan’s chance of success?

1. Many tourists who visit these parts of the Caribbean are uninterested in manatees and would not be willing to pay what the former manatee hunters would have to charge for boat rides to see manatees.
2. Recovery of the species would enable some hunting to continue without putting the manatees’ survival in jeopardy again.
3. In areas where manatees have traditionally been hunted for food, local people could easily replace the manatee meat in their diets with other foods obtained from the sea.
4. There would not be enough former manatee hunters to act as guides for all the tourists who want to see manatees.
5. To maintain their current income, manatee hunters who switched to guiding tourists would have to use far larger boats and make many more trips into the manatees’ fragile habitat than they currently do.

   Answer: E

我的答案是A

我对这两题的答案都有疑问，不知哪位大侠能帮解答一下

第一题中，文章的结论是从塌落可以看出，一点点不符合安全标准都可能导致严重后果。A说，另外一个塌落的屋顶就是因为没有遵循安全标准。加强。

D是无关选项，房屋的柱子和屋顶有关系么？文章没有提吧。你可能是想，柱子也不符合标准所以导致屋顶塌陷，加强啊？其实你是默认了柱子时用来支持屋顶的，这文章可没提到。

第二题，削弱体。文章认为猎人不打动物了，动物就不会endanger了，E指出，由于旅游的开发，动物的栖息地受到威胁，也可能导致动物endanger。所以这个通过开发旅游来保护动物的计划不可行。

文章已说了Tourist interest is high, 做题要承认事实的正确去反对结论。就算前提告诉你太阳绕着地球转你也要承认这点正确。

欢迎批评指正！

第一题: 加强题. 结论是: even a single, apparently insignificant, departure from safety standards can have severe consequences

A正确. A排除了他因的可能性. 如果仅有的另一幢倒塌的楼是幢造在低标准的safety codes时代, 那NC’s equipment-storage building的倒塌只可能是钉子大小(a single, apparently insignificant, departure from safety standards) 的问题

D错. D加了他因. 柱子不牢固+钉子大小就不是a single departure.

第二题. A无关. 原文已经说了Tourist interest is high. 来Caribbean游客有没有兴趣无关.
