一道逻辑题from manhattan~~~原文中的survey调查究竟有没有毛病？？

City Controller: 63% of our residents voted to approve the developer's request to build a national chain hotel on the site of the old consignment store. The hotel will increase our revenue base and, therefore, provide more money for schools and community services.
Mayor: But our recent survey showed that the most important reason people want to live here is our small-town feel resulting from the local ownership of the vast majority of businesses.
What is the best explanation for the apparent contradiction in opinions cited by the controller and the mayor?
a. Most people believe having a small-town feel is more important than having quality schools.
b. A locally-owned business might be able to generate as much revenue as a well-known hotel chain.
c. The recent survey did not ask about preferences for a chain hotel versus a locally-owned bed and breakfast.
d. An increase in the town's revenue base may not result in additional money for the schools.
e. The recent survey cited by the mayor polled people who are considering moving to the town.
这题选E是米有问题的~~但是个人认为矛盾点在于mayor调查对象的选取是有问题的，只是选取了想要搬进这个town的那些人，样本无代表性 可是我的BF认为survey没有问题，本来这个survey就是针对于想要搬进这个town的人的…… 大家来讨论呀大家来讨论~~

这个题目的关键就是调查人群的差异。不管是什么导致了这个差异，双方所调查的人群肯定不一样，否则无法解释看上去的差异。所以，要选择能够导致调查人群不一样的选项。
没有什么必要去找到这种差异的罪魁祸首，到底是survey设计出错了，还是第一个统计的方法有问题，这毫无意义。反正就是双方的人群不一样。
能导致这种差异的因素太多了，我可以列出无数虚构的原因：1. 样本数量太小 2. 采样的时间不一样（上班时间 vs 下班时间）3. 性别差异 4. 年龄差异 5. 收入水品差异
反正随便那个都行。
那个题目里就E是讨论人群样本差异的，所以 E 正确。

诸位，Manhattan的逻辑值不值得看？  还是做VERBAL的逻辑？
