Q21:

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.

   我当初选的D，现在想到D项说的是building-safety codes，而结论说的是departure from safety standard,所以D错；A当初我排除是看到了The only other buildings ，认为是无关项，但是现在明白结论是泛谈，所以用other building无可厚非，且有less exacting standards than those in the safety codes，不知道我这样想是否正确，望高手点墨赐教，不胜感激

题目要加强的是结论：房顶的塌陷反应了细小的微不足道的对于标准的背离可以造成严重的后果。文章的支持是一个小螺丝的例子。

A说倒掉的就是那些没有按照标准建造的老房子，

加强。

D说的是房子塌了有可能是柱子不够结实，未必是螺丝的问题，从而削弱结论。
