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?

1. 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.


2. The sales of snacks and drinks in its movie theaters account for more of Lightbox’s profits than ticket sales do.


3. 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.


4. Spending on video purchases, as well as spending on video rentals, is currently no longer increasing.


5. 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.

pls confirm the answer is C

我觉得是A

A和C好象都能增加潜在观众. 想了半天也无从取舍, 请NN继续讨论.

A, the confirmed answer according to my answer key.

C--the result might or might not lead to increase profit.

agree with A

A说人数不变但是组成的部分变了，还是说会去看片的人多了（本来要是depends on的话，光增加人数也没用，还得增加看片的人数才成。

C

請問為何C錯

A: a younger, more affluent, and more entertainment-oriented population is expected to occur.

                                                                                                                    表未來的情形, 可以起weaken的作用嗎?

对于都增加潜在观众的问题，我认为A、C的区别在于A所强调的是即将发生（如果预测为真则会weaken结论，是典型的正确选项），而C所说是一个持续的过程（过去和现在也是这样的policy,那时没什么效果，将来也不一定就有效果）。
