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.
Which of the following, if true about Washington County, most seriously weakens the argument?
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.
The sales of snacks and drinks in its movie theaters account for more of Lightbox's profits than ticket sales do.
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.
Spending on video purchases, as well as spending on video rentals, is currently no longer increasing.
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.
因果推理：由于is only just large enough for profitability now 和人数不变 果： 盈利不会增加
方案推理：double the number of movie screens 目标：profitable 本文的答案倾向于推理是方案推理
A的意思是，即使人口总量不增加，而人口中那些更年轻，更注重娱乐的青年人大大增多了，就可能使得进电影院看电影的人多了，因此，收入就增加了
C避免放那些叫好不叫座的电影，这是一个任何情况下电影院都可以采取的策略，和增加电影院没有直接的关系，也不矛盾，也就是说，即使不增加电影院，也可以通过采取这样的措施来增加放映收入。所以，它是增加收入的理由，但不可能成为增加电影院的理由，而问题的关键在于增加电影院这样的措施对不对
A--这个方案是可行的 C--与方案无关
