GMAT逻辑答案:

　　Reasoning

　　In order to adequately support the arguments conclusion, what piece of  information must be an implicit part of the argument? The conclusion of the argument is residents’ complaints about night flights that disturb their sleep are unreasonable. The officials point is that if the residents chose to move into an area with noisy night flights, they cannot reasonably complain about those flights. But this presupposes that the area already experienced noise from night fights when the residents moved there; that the residents knew or should have known about the noise when they bought their homes; and that they could have chosen to live elsewhere. Therefore, look for an answer option that expresses or follows from one or more of these assumptions.

　　A. The point could make sense even if the frequency of night flights hasn't changed.

　　B. Correct. As explained above, the argument presupposes that the night flights were already happening when the complaining residents first moved to the area; since the night flights started twenty years ago, the argument assumes the residents moved there less than twenty years ago.

　　C. Even if the residents acknowledged the benefits they gain from the airport, their complaints about the night flights might still be unreasonable.

　　D. Even if the airport could scrape by without night flights, the residents’ complaints about the night flights might still be unreasonable.

　　E. Without assuming this, the argument would still be successful--for example, even if it included the information that no homebuyers who can avoid buying houses near the airport do so.

　　The correct answer is B.
