请教NN两道GWD的逻辑题，LZ不明白~~
Q21:
In January of last year the Moviemania chain of movie theaters started propping its popcorn in canola oil, instead of the less healthful coconut 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?

A.Total sales of all refreshments at Moviemania’s movie theaters increased by less than 5 percent last year.

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

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

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

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

这个题为什么要选A呢？是用什么比例关系确定的么？

Q14:
Smithtown University’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted.This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job.On the contrary, since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base.The high success rate shows insufficient canvassing effort.

Which of the following, if true, provides more support for the argument?

Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.
This year the average size of the donations to Smithtown University from new donors when the university’s fund-raisers had contacted was larger than the average size of donations from donors who had given to the university before.
This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the university’s fund-raisers having made any contact with the donors.
The majority of the donations that fund-raisers succeeded in getting for Smithtown University this year were from donors who had never given to the university before.
More than half of the money raised by Smithtown University’s fund-raisers came from donors who had never previously donated to the university.
这道为什么也选A呢？LZ选了C，但是再仔细看C怎么觉得越看越绕看不明白呢？？？

1 卖的popcorn 增长了5%，来的人增加不到5%，说明人均买的爆米花多了，人们还是挺喜欢这种爆米花的。更加反驳了Moviemania’s claim。
2 捐钱这个是个很恶心的题~

A Smithtown University’s fund-raisers were successful in their contacts with potential donors who had never given before about as frequently as were fund-raisers for other universities in their contacts with such people.

C This year most of the donations that came to Smithtown University from people who had previously donated to it were made without the university’s fund-raisers having made any contact with the donors.

原文：一群人联系的人里面，有80%都同意给他们捐款---->这群人成功率高；成功率高是由于是老“客户”原因，不需要他们怎么努力就能上钩。因此，这高成功率说明他们不够努力。

全文都再围绕成功率讲解，那到底这么高的成功率究竟能不能说明他们不够努力？
看选项a，“这群人在劝说新客户时和其他大学是一样的”。
看原文红色字和这个选项连起来，“他们拉人成功率比其他大学高，但是他们拉新客户成功率和其他大学一样”这不就说明他们努力不够，只是去拉那些不怎么需要努力就能拉倒的老客户么，靠这些老客户来提高的成功率。

c选项，most的是 donations ，不是er，捐款钱数和捐款人数无关。不一定大部分捐款来自老客户，老客户人数就多。

这道题句子读起来太难了，选项还绕~

希望说明白了`
