嗯嗯  这题我是做对了  就是以为会有更好的思路。谢谢啦！

我说的方法前面要有一大堆balabalabala，逻辑很饶，这题前面就一句background，有啥意义用那个方法？

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?
A. 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.
B. Megaplex makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.
C. 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.
D. Total sales of all food and beverage items at Megaplex's movie theaters increased by less than five percent last
year.
E. Total attendance at Megaplex's movie theaters was more than 20 percent higher last year than the year before.

大神大牛你好，能麻烦解释一下以上这题吗？

我自己琢磨的是这样：
P：去年爆米花用油从coconut oil转为更健康的canola oil
这个转变导致了爆米花销量下降要再用回coconut oil
去年实际销量上升了5%
C：不要用回coconut oil
weaken结论，那就是要找出用回coconut oil的理由

一开始错误的选择了C，想的是反正没人关心用的什么油，换不换回去都无所谓，是不是也可以在一定程度上起到削弱作用呢？
求指教，感谢~

你的前提和结论都找错了：
前提：according to Megaplex's own sales figures, Megaplex sold five percent more popcorn last year than in the previous year.
结论：That claim（he change has hurt popcorn sales） is false

这是一道明显的“绝对与相对”类型的削弱题：
爆米花销售跟去年比涨5％ 是一个“绝对”的比较，在没有参考系的情况下，“涨5％”可能意味着“增长”也可能意味着“倒退”：比如E，在观影人数增长了20％的情况下，爆米花销售比去年增长了5％，显然是种明显的“倒退”。

一开始错误的选择了C，想的是反正没人关心用的什么油，换不换回去都无所谓，是不是也可以在一定程度上起到削弱作用呢？
C既不加强也不削弱，因为C无关。注意从前提到结论的过程，是从“数据”到“结论”，跟人们对油的态度有半毛钱关系吗？削弱也必然是从“数据”的有效性，代表性入手说明从前提到结论的过程是有问题的。

只有把前提和结论找对才能做对题目啊~
