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.
21.Which of the
following, if true, most strongly supports the editorial\'s argument?
A 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.
B 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.
C 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.
D The columns of the building were no stronger than the
building-safety codes required for such a building.
E Because the equipment-storage building was where the
council kept snow-removal equipment, the building was almost completely empty
when the roof collapsed
a的意思是只要符合standard就不会塌，b的意思是房屋顶子塌掉了是由于该房子的上的雪比别的房子上的厚重，而不是质量问题
