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?

【选项】Because the equipment-storage building was where the council kept snow-removal equipment, the building was almost completely empty when the roof collapsed.
