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.
