Airport official: Local residents have been complaining that night flights into Plainsville airport disturb their sleep and should be sharply reduced in number. This complaint is completely unreasonable—there have been night flights coming into the airport from the very beginning, twenty years ago, and these residents should have taken that fact into account when buying their homes.
Which of the following is an assumption on which the airport argument depends?
There are fewer night flights now than there were originally.
The residents who are complaining have been in their current homes fewer than twenty years.
The residents who are complaining are ignoring the benefits they gain from the presence of the airport.
The economic success of the airport depends entirely on the existence of the night flights.
People buying houses in Plainville all avoid buying houses near the airport if they can.
【因果】因-20年前选房时已经注意到有飞机场。果-投诉不应该发生。当做取非削弱来做，B取非-那些抱怨的人已经在这住了20及20年以上了，结论严重被否。同时，要注意到即使在因果中的削弱，也是应该是选项+因才不能导致果的发生，而不是选项单单就可以让果不存在，比如“飞机场倒闭了”
非常受用，但是我为什么想不通A啊？从开始建机场就与夜晚航班了，现在航班少了，所以你就不应该还抱怨了啊~
非常棒
