Theatergoer: In January of last year, the Megaplex chain of movie theaters started popping its popcorn in canola oil, instead of the less healthful coconut oi that it had been using until then. Now Megaplex is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Megaplex's own sales figures, Megaplex sold five percent more popcorn last year than in the previous year.
Which of the following, if true, most seriously weakens the theatergoer's argument?
When it switched from using coconut oil to using canola oil, Megaplex made sure that the chain received a great deal of publicity stressing the health benefits of the change.
Megaplex makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
In a survey to determine pubic response to the change to canola oil, very few of Megapiex's customers said that the change had affected their popcorn-buying habits.
Total sales of all food and beverage items at Megaplex's movie theaters increased by less than five percent last year.
Total attendance at Megaplex's movie theaters was more than 20 percent higher last year than the year before.
考虑到影院观众所陈述的事实，什么更有可能使从椰子油转向菜籽油损害了影院爆米花的销售?影院在去年年初开始改用菜籽油，而他们的销售数据显示，在调整后的一年中，他们卖出的爆米花比调整前一年多了5%。因此，有证据表明如果影院没有改用菜籽油，爆米花的销量甚至会增加5%以上的答案选项将支持影院声称的改用菜籽油影响了爆米花的销售。
e. 如果电影院的总观影人数增加了20%，而爆米花的消费只增加了5%，那么每个顾客的平均爆米花销量就下降了。因此，菜籽油的使用可能会阻碍顾客购买爆米花。
