穷尽了一切方法都没办法想通的一道逻辑题PREP 2012 PACK1 CR 56

Pretzel vendor: The new license fee for operating a pretzel stand outside the art museum is prohibitively expensive. Charging typical prices, a vendor would need to sell an average of 25 pretzels per hour to break even. At my stand outside city hall, I average only 15 per hour. Therefore, I could not break even running a pretzel stand outside the art museum, much less turn a profit.
Which of the following, if true, most strongly supports the pretzel vendor's argument?


A. There is currently no license fee for operating a pretzel stand outside city hall.

B. Pretzel vendors who operate stands outside the art museum were making a profit before the imposition of the new license fee.

C. The number of pretzel stands outside the art museum is no greater than the number of pretzel standsnow outside city hall.

D. People who buy pretzels at pretzel stands are most likely to do so during the hours at which the art museum is open to the

E. Fewer people passing the art museum than passing city hall are to buy pretzels.

不明白我们要支持的点是什么？题目的意思是？

Reasoning Given the facts the vendor has stated, what would make it less likely that the vendor could break even running a pretzel stand outside the museum? The vendor says that to break even, it would be necessary to sell more pretzels per hour outside the art museum than outside city hall. Therefore, look for an answer choice suggesting that the vendor could not sell that many pretzels outside the art museum. To strengthen the argument, the correct answer must present evidence that goes beyond what the vendor has already stated.
A. Alicense fee outside city hall would not affect the vendor's need or ability to sell 25 pretzels an hour outside the artmuseum to break even.

B. If vendors were making a profit before the license fee was imposed, there might be enough demand for pretzels to allow a profit even with the license fee

C. Fewer pretzel stands outside the art museum would mean less competition. Therefore, it might be easier for the vendor to make a profit

D. Even if many more people buy pretzels while the museum is open than when it's closed, the vendor might still sell at least 25 pretzels an hour, on average, whether it's open or closed.

E. Correct. If the vendor only sells 15 pretzels an hour outside city hall,and fewer people want pretzels outside the art museum than outside city hall, then it would be hard for the vendor to sell 25 pretzels an hour outside the art museum.

The correct answer is E.

这是一道类比题，类比题出现在weaken题型中，就找dissimilarity, 出现在strengthen中，就找similarity.

前提：艺术馆门口需要卖25个/hr才能保本，而市政厅门口都只能卖15/hr，所以作者推测艺术馆门口很难赚钱。

那么要加强，则找similarity，那就是艺术馆和市政厅门口的客户量是一样的。

E选项，说艺术馆的客户质量还不如市政厅，这不是更加成立了吗。

我和你理解的一样！

挖坟了一道题，但是我怎么觉得这道题应该是这样理解：
premise：新的在museum外的执照费很贵
如果Charging typical prices，这里的price是指pretzel的price，而不是license的（因为是vendor charging啊，如果是license fee的话应该就是charged了吧），就是说如果售价不变，那么在博物馆外要卖25个break even，在city hall外卖15个回本
所以在售价不变的情况下，license fee涨了，就得卖的更多（ E:买的人更多）才能回本，反过来说就是没人买就更回不了本
conclusion：在museum外赚不回来钱

思维有点乱，望指正

。。。噗。。切糕够犀利。。。这个题瞬间就记住了。。

这个……还是蛮直接的啊……
题目：艺术馆外摆摊费太贵了，我要每小时卖25个才能收支平衡。我在市政厅外的摊儿每小时卖15个。所以说，我在艺术馆外摆摊肯定要亏大钱的。
其隐含逻辑：市政厅外每小时15个，所以估算艺术馆外也差不多这个数量。
题目：能够说明上述reasoning可以成立的，即支持其逻辑成立的。
所以是 E啊，艺术馆外买的人比市政厅还少。。。。【不要过度联想。。。逻辑就是选最直接相关的那项，不要是七拐八拐之后才有关联的项。。

and 如果题目是问 weaken的项，那基本上就是说能卖掉很多很多个的那一项。。
【个人观点，仅供参考……】

椒盐饼干供应商说：在博物馆外摆摊的新营业执照费是在太贵了。按照以前的执照费用，一个小贩需要每小时卖25个椒盐饼干才能达到收支平衡（保本）。而我摆在市政府外面的小摊，平均每小时只能卖15块椒盐脆饼。（此处补充结论：E、何况路过博物馆买饼的人比路过市政厅买饼的人少）

因此，我如果在博物馆外面摆摊，根本无法达到收支平衡，更别提盈利了。

买买提：
premise:新执照太贵了吧
evidence:按照传统的执照费，我只需要每个小时卖25个切糕就能盈利了。但是我站city hall每个小时只能卖15个切糕啊！
conclusion:我在博物馆门口卖切糕绝对无法盈利生活还过不过了尼玛

要支持的就是结论。站博物馆门口不能不能盈利

A. cityhall 现在没场子费， 无关（ 驻在博物馆，管cityhall收不收钱毛事？）
B.在新制度之前，切糕车在博物馆可是利润肥厚的。   不充分（以前能赚，新制度来了也有可能赚）
C.博物馆外的切糕车比cityhall的切糕车少    （那博物馆竞争少，岂不是更赚？ 削弱）
D.（貌似不全？）博物馆开张的时候，市民才来买切糕啊 （有毛关系？）
E.在博物馆附近买切糕的人比路过cityhall买切糕的人还少啊！   支持（n＜15＜25=悲剧）
