OG11-113

     Since the deregulation of airlines，delays at the nation's increasingly busy airports have increased by 25 percent．To combat this problem，more of the takeoff and landing slots at the busiest airports must be allocated to commercial airlines．

Which of the following，if true，casts the most doubt on the effectiveness of the solution proposed above?

(A)  The major causes of delays at the nation's busiest airports are bad weather and overtaxed air traffic control equipment．

(B)  Since airline deregulation began，the number of airplanes in operation has increased by 25 percent.

(C)  Over 60 percent of the takeoff and landing slots at the nation's busiest airports are reserved for commercial airlines．

(D)  After a small Midwestern airport doubled its allocation of takeoff and landing slots，the number of delays that were reported decreased by 50 percent。

(E)  Since deregulation the average length of delay at the nation’s busiest airports has doubled

答案是A，看了解释以后我可以理解。但是C为什么不对呢？如果大部分的slots是commercial airlines的，那么说明delays是commercial airlines的责任，那么再分配给它们slots不能减少delays，不就most doubt on the effectiveness of the solution了嘛

这是snowmary问过的问题，但是没有人回答~于是沉入水底~~请教各位XDJM的解答

这是OG10-113 不是11

小明有4只苹果 lz有6只 60%  于是我再给小明2只 反而是加强不是削弱

即使按照lz的理解 那也有40%给了非commercial airlines 照样加强

payo你的意思是c取非后是加强而不是削弱吗？~~呵呵~~~我的脑子转不过来啊！能不能说得详细点呢？
