首先我们看三道assumption题

一道逻辑题来自阅读理解36套
On turning 65 years old, everyone living in the town of Malton becomes eligible to receive a card that guarantees discounts on most goods and services sold in the town. Census records for 1990 show that 2, 450 inhabitants of Malton turned 64 in that year. Yet . in 1991 over 3,000 people applied for and properly received discount cards. So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid -60's$ ~/ ~8 h/ T/ R- ~0 v& ]) k) ?8 P

Which of the following is an assumption on which the argument depends?, Y* V! k1 ?: t' w6 c( f2 T/ g6 \
(A) The town of Malton has no complete census records for 1991.
(B) The overall size of the population of Malton grew by over 500 during 1990.

At the Shadybrook dog kennel, all the adult animals were given a new medication designed to reduce a dog‘s risk of contracting a certain common infection. Several days after the medication was administered, most of the puppies of these dogs had elevated temperatures. Since raised body temperature is a side effect of this medication, the kennel owner hypothesized that the puppies‘ elevated temperatures resulted from the medication‘s being passed to them through their mothers‘ milk.
8. Which of the following, if true, provides the most support for the kennel owner‘s hypothesis?
(A) Some puppies have been given the new medication directly but have not suffered elevated temperatures as a side effect.
(B) The new medication has been well received by dog breeders as a safe and effective way of preventing the spread of certain common canine infections.
(C) None of the four puppies in the kennel who had been bottle-fed with formula had elevated temperatures.
(D) an elevated temperature is a side effect of a number of medications for dogs other than the new medication administered at the kennel.
(E) Elevated temperatures such as those suffered by most of the puppies in the kennel rarely have serious long-term effects on a puppy‘s health

虎平老师更正后的答案是D。。。。 想不通啊 为什么C错了呢？

这三个题中间 迷惑的选项都让人感觉更能支持文章
但是 结合argument里对assumption题的要求和写法
我们是不是对assumption的理解有误？
与其说是选择support的选项 倒不如的选择作者的预设立场？ 正如在argument里头我们攻击的那样。。。。。

assumption
1 [count] something you consider likely to be true even though no one has told you directly or even though you have no proof
2 [uncount] a process in which you begin to use your power or status, or begin to be responsible for something:

我充分的觉得这三道题的答案是给错了....

请问这是什么词典啊？

楼主最后的理解是对， assumption 题 基本不会去对论据思考，主要是找到hidden premise
建议楼主去看GMAT逻辑，收获会很大
第一题Census records for 1990 show that 2, 450 inhabitants of Malton turned 64 in that year. Yet . in 1991 over 3,000 people applied for and properly received discount cards看做A
So clearly some of Malton's population growth between 1990 and 1992 must be attributable to migration into the city by people in their mid -60's$ 为B的话，选项D的意思是 让A可行， 比90年多出的550全是65的而且都接受了卡片，E选项是对A的再次陈述

mnjcqwiUID: 3147059

第二题 楼主理解错了 这题是支持类题目，C如果是假设类的题目他是对，但这是支持类，而D的选项是直接支持的结论的

第3题An economist concluded that Kregg Companydeliberately discriminated against people with a Whistory of union affiliation in hiring workers for its new plant. 为A。1,500 people hired to work at the new plant, only had ever belonged to a labor union, whereas in Kregg Company's older plants, a much higher proportion of 为B 即为A推出B ，那么D选项是是非B推出非A，正好是A B的逆否命题。A选项和题目想反 题目中有属于union的在NEW plant,BC 都是如此。E选项提出一个候选人的概念，和题目是没有关系的，在假设类题目中有新的概念基本就是错了

抱怨下 这里每个问题帖子的点击率都100以上。单每次回答的都是版主，各位GRE某种意义上是RP考试，当你不为别人服务的时候，只想去白得，你怎么去赞人品。 阿弥陀佛

多谢楼上的解释 原来果然是一直理解错了啊 这就去看看GMAT的逻辑题去

关于互相回答问题什么的 倒是也有这种感觉
不过 更多时候应该是版主超尽职的关系吧。。。。。
大家刷网页刷的也不是很勤 经常进去的时候就发现版主已经回答过了。。。。
也有时候是因为自己也不懂。。。。。

如果正好没人回答过而且自己又明白的话大家都会回答吧

你的分析似乎有点问题，我觉得assumption是用来支持结论的。也就是说assumption是让"事实->结论"的推理过程更加合理的条件。所以assumption并不是为了让事实看上去可行。
如你对第一题的分析，A是事实，B是结论，那么就要找A+哪个选项能合理的推出B。
