Q23:

In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut （n.椰子）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

1. percent last year.排除另一种可能，支持


2. Moviemania makes more money on food and beverages sold at its theaters than it does on sales of movie tickets.无关


3. Moviemania’s customers prefer the taste of popcorn popped in coconut oil to that of popcorn popped in canola oil.反对


4. Total attendance at Moviemania’s movie theaters was more than 20 percent higher last year than the year before. 削弱


5. The year before last, Moviemania experienced a 10 percent increase in popcorn sales over the previous year.无关

答案是A

这题我花了三分钟 请问A为何支持呢

是不是排除了一种可能性 即小吃销售的增长 导致爆米花的增长

谢谢

A indicates that popcorn sales is actually doing pretty well comparing with that of other refreshment, therefore using canola oil didn't hurt the popcorn sales.

同意ROBERTCHU。A实际上是用比较的方式说明用canola oil爆爆米花能使popcorn的销量增加。因为自从用canola oil爆爆米花后，popcorn的销量增加比其它点心销量增加快。也可以说是用比较的方式排除其它原因使popcorn的销量增加，增加就是用canola oil的原因使popcorn的销量增加的可能性

谢谢robert/ lawyer

我的理解是

排除了一种可能性 即小吃销售的增长 导致爆米花的增长

对不对

谢谢

“排除了一种可能性 即小吃销售的增长 导致爆米花的增长。”WRONG。爆米花是小吃的一种。排出的可能性是使整体小吃销量增长的原因也是爆米花的增长这末快，比如现在看电影的人，所以销量都长，A说这个原因只能是使爆米花长低于5%，剩下增长部分是使用canola oil的原因。

谢谢lawyer 我想我理解对了

在GWD的逻辑中 发现了多个层次的论证 经常是X支持Y  Z反对X  X又辩护 等等

就如这题

我感觉读完题目没法判断要求的是什么

请问大家在做题中有没有这样的问题 是如何解决的

谢谢

你的问题太泛，不过除MUST BE TRUE，SUPPORT THE CHOICE，RESOLVE PARADOX题外，多数都有一个主结论，即作者要表达的意见，其它都是PREMISE和BACKGROUND，这两者中有时有SUBCONCLUSION。该题，第一句为BACKGROUND，第二句为待放反驳的观点（你将它当作主结论的背景也可），为第三句包括结论和PREMISE，PREMISE用SINCE表示，结论是CLAIM IS FALSE。分清原文的主结论和PREMISE是最关键的，这样才有做题的起点

如果是问WEAKEN的话,应该选哪个选项啊?

lawyer_1

如果WEAKEN的话，应选D。人数增加20%，而销量才增加5%，说明这种爆米花还不如原来的爆米花有销量。C不起WEAKEN作用，不管人们喜不喜欢，销量是增加的，这是事实，不容否定，销售商要的也是销量，人们喜不喜无关，只要销量上去就行。
