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'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.
不懂，题目到底是问加强还是削弱oil的变化对sales带来的影响啊
