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.
-Airport的结论是建立在怎样的基础上？
-居民完全有能力预知风险，他们应该自己负责机场噪音的影响。
B.如果是20年之前搬来的居民当然有资格投诉机场，但20年之内搬来的都是已知机场噪音后作出的选择。
E.如果居民都尽量避免，那么选择在机场附近的居民都是迫于无奈。他们有可能投诉也有可能不投诉
