龙飞凤舞

我开始支持C的，后来看了半天，觉得A更好

有时不要死扣，因为确实从C角度来说也能profitable，

但是文章最后一句话：Clearly, therefore, if there is indeed no increase in population, Lightbox’s new screens are unlikely to prove profitable.

再看A：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.

A中的Though就是让步，顺着题目意思往下讲，提出另外一个可能性，从而削弱。

即使选A，都不能完全说C错
