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?

1. Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.

2. Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.

3. Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.

4. Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.

5. The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.

为什么选a      谢谢

M觉得canola oil 时候的销量不如 coconut oil的销量，想换。------M的claim

文章中给的against是说销量提高了5%

问题：support the argument against M ---------怎样利用文章给定的信息说明，M的claim是错误的，即用canola oil好

A，如果多了3%的人进入，而多销售了5%的东西，那么average是多了

   如果 多了10%的人进入看，而多销售了5%的东西，那么average是少了

其他的就挺无关的了

哦~其他小吃增加的不足5%，而只有这个增加超过了5%  （可能是别的小吃的人被吸引过来了）
