In January of last year the Moviemania chain of movie theaters started popping its popcorn in canola oil ,instead of the less health cconut oil taht it had been using until then. Now Moviemania is planing to switch back, saying that the changes has hurt popcorn sales. that claim is false, since according to Moviemania's own sales figures, MOviemania sold 5 percent more popcorn last year than in the previous year.
which supports the argument against Moviemania's claim?
A total sales of all refreshments at Moviemania's movie theaters increased by less than 5 percent last year...
A is the answer 请问怎么理解？ 是说，其他的都没有popcorn的利润高吗？ |
