In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Moviemania is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Moviemania’s own sales figures, Moviemania sold 5 percent more popcorn last year than in the previous year.

Which of the following, if true, most strongly supports the argument against Moviemania’s claim?

A.    Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.
B.    Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
C.    Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.
D.    Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.
E.    The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.
答案给的是A，但是all refreshment不属于扩大范围吗？请NN指点,thanks!

我的理解是， 如果来电影院的人多了10%， 如果爆米花的销售量增加了5%， 那就是爆米花的销售变坏了。 这里说到all refreshments的销售增长没有到5%， 而爆米花的销售量增加了5%， 就说明爆米花的销售还是更好了。

多谢！我开始的理解是refreshment还包括了其他的东西，没有考虑以5%为标准的相对比较。
