Critical Reasoning
试题详情
题目：
Lightbox, Inc., owns almost all of the movie theaters in Washington County and has announced plans to double the number of movie screens it has in the county within five years. Yet attendance at Lightbox's theaters is only just large enough for profitability now and the county's population is not expected to increase over the next ten years. Clearly, therefore, if there is indeed no increase in population, Lightbox's new screens are unlikely to prove profitable.
选项:
A、Though little change in the size of the population is expected, a pronounced shift toward a younger, more affluent, and more entertainment-oriented population is expected to occur.
B、The sales of snacks and drinks in its movie theaters account for more of Lightbox's profits than ticket sales do.
C、In selecting the mix of movies shown at its theaters, Lightbox's policy is to avoid those that appeal to only a small segment of the moviegoing population.
D、Spending on video purchases, as well as spending on video rentals, is currently no longer increasing.
E、There are no population centers in the county that are not already served by at least one of the movie theaters that Lightbox owns and operates.
答案:
A
提问：
纠结AC，错选C。老师麻烦分析一下AC这两个选项，并解释一下C为什么不对。因为我的理解是选项C说会避免选择不那么受欢迎的电影。我觉得这个条件，在人口基本不变的情况下，可以导致看电影的人变多。

提问：
可是A选项它说人口逐渐逆老龄化，年轻人越来越多，有钱的人越来越多，就证明一定会去电影院吗，不去的话，电影院也不能挣钱，对于一个选项有争议的也不能作为正确答案呀？

提问：
1267）的8XXX的次方- （1266）8XXX的次方。该结果的个位数是多少？
（8XXX除以4余2； 1267、1266数字乱编，但是个位数是对的，关键点就在于个位数）~~By kicobao
狗主思路很对！1267个位是7，那么7n有四种个位：7,9,3,1。8xxx除以4余2，那就是第二个了，即个位为9。 同理，1266个位是6，6n个位都是6，所以该结果的个位数是9-6=3^_^
【V2】1267^8257-1266^8256，求个位数（数值记不太清了，不太准确）～～By special_game
这个版本的指数是不一样的~不过没关系，思路同上，8257除以4余1，所以1267^8257的个位数是7, 1266^8256的个位数依旧是6，所以7-6=1

提问：
我读A时觉得句意的重点应该是一群更年轻更affluent更什么娱乐的青年将出现，完全客观的思想觉得跟原文没有任何关系，而B中提到了利润原文有涉及，所以选了个B。
