26. Editorial: The mayor plans to deactivate the city's fire alarm boxes, because mostcalls received from them are
false alarms. The mayor claims that the alarm boxes are no longer necessary, since most people now have
access to either public or private telephones. Butthe city's commercial district, where there is the greatest risk
of fire, has few residents and few public telephones, so some alarm boxes are still necessary.
Which of the following, if true, most seriously weakens the editorial's argument?
(A) Maintaining the fire alarm boxes costs the city more than five million dollars annually.
(B) Commercial buildings have automatic fire alarm systems that are linked directly to the fire department.
(C) The fire department gets less information from an alarm box than it does from a telephone call.
(D) The city's fire department is located much closer to the residential areas than to the commercial district.
(E) On average, almost 25 percent of the public telephones in the city are out of order.

正确答案是B~我先过问一下~C选项说的是和文章的条件相反~为什么不能weaken呢... 不是说if ture，也就是说我们选的答案里的内容是真实的话，能weaken就可以么?
