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?

Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.
Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.
Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before.
The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.

the line of reasoning: Moviemania sold 5 percent more popcorn last year than in the previous year--->the claim that the change has hurt the popcorn sales is false.

A:total sales of all refreshment increased less than 5%.可以加强原推论，表明这个改变的确是促进了popcorn的销量。
反之想如果total sales increased more than 5%，而popcorn是5%，那么即使销量增加，也表明change带来的是负面影响。
