In general, jobs are harder to get in times of economic recession because many businesses cut back operations. However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools. This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
Which of the following, if true, most strengthens the argument?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项
当前版本由 OoO 更新于2016-11-01 21:06:56 感谢由 OoO 对此题目的解答所做出的贡献。B选项说,已经有25%的学生在私立学校。而题干说公立学校就算萧条老师也不会失业,但是,一但萧条,那25%的学生怎么办呢?当然是选择免费公立学校,而公立的老师数量不会减少,学生增加了。
但是规定,学生-教师比例不能超过现在,所以,老师也要增加,而原文的ARGUEMENT是 any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools
所以当然是支持,那25%学生涌进公立学校教师必须增加才行,才能保证legal requirement。
所以,正确答案为B。

其实这道题分析明白了以后非常简单,答案也很好理解,可能这个类型具有一些典型的难题,应该分析清楚。
题目的前提是两组数字之间变化的关系,这道题是学生的数字和老师的数字关系,也就是设定了一个分数,这道题是公有学校的师生比例。然后给定了一个条件,描述了这两组数字未来可能发生的变化,也就是分数可能发生的变化,这道题是给了分数值不能变高。然后题目开始出另一个推理的条件,这道题是老师的数量要增加,也就是分母要增加,如果要保持数值要保持不变,只能从分子下手。
答案就是一切有可能让分子也就是学生数量增加的选项,这道题是因为经济萧条更多的学生选择了公立学校,注意这个结论也是进一步推理才得出的结果。如果这道题能分析明白,相信以后遇到这类的题,可以很快找到答案。
此外,这道题的题干和答案描绘的都很隐晦,增加了阅读理解的困难,也是难题的典型特征。
B选项是取非: 说的是经济好的时候学生去私立。经济差的时候学生来公立

C: any future recessions will probably not reduce the availability of teaching jobs教师从业人数不会减少 P1:政府提供免费的公立教育 P2:政府规定学生和老师要有一个比例,不能被超过 那么这里重点是这个比率,要保证老师数量不能下降的话,学生的数量就不能下降,P1的条件就说明了未来学生数量可能会增加的原因,两个综合起来就是B选项。 所谓的有关无关就是根据这个P-C论证过程来确定的,不是内容上的相关性。 能够影响结论 any future recessions和 teaching jobs的数量的只有B 选项AC选项那现在和过去比,那你怎么能确定未来是什么情况呢?其他的都是无关的,理解一下(摘自其他网站解答,清晰易懂,还是我太菜了)

我感觉E应该用过去一次recession的情况类比推测此次:recession——永久关停公立学校+公立学校师生比不变——教师岗位总数减少——削弱

觉得gwd脑回路有问题的终于不是我一个了

我真的服了,有些题目过去情况能削弱现在的情况,有些题目又完全撇清过去情况与现在情况的关系

有空间 如果private school没人,那recession后不会有students进入公立学校 AC比较的时间无关

GWD脑回路有问题 跟GMAC的人还是有很大差距的

E的逻辑为什么不对啊?已经关掉了很多学校,所以剩下的公立学校就稀少,就更加valuable,有限的学校里师生比例不变,学生增多那老师职业肯定能获得保障啊
gmg回复gmg
说b是正确的逻辑不也是自己推测出来的吗--”那25%的学生怎么办呢?当然是选择免费公立学校“。。那我说25%的学生就算经济萧条,他们依旧有钱上私立学校啊,

我刚开始也是这样想的,但是后来又觉得,因为关的是公立学校,所以学生少了,老师也走了,然后学生和老师都会去现存的公立学校,即学生和老师的总数和比例其实没有变,只是学校少了而以,所以E不影响

A 现在比例已经高了,起到反作用,而且说的是未来的事,过去不能决定未来。 B 1/4的学生到时都会来公立,也需要更多老师。 C 比上次萧条之前多,起反作用,跟过去比不说明问题。 D 无关,有点反作用,工资越高竞争越激烈 E 完全削弱,学校都关了,还要老师干嘛。 感觉就是不要想太多,把自己给绕进去。

做的时候AB犹豫 A:现在s/t有点高了-即s多t少,那不是直接说明缺t→加强了题目not reduce teacher吗 B:经济好的时候,25%s去很贵的私立学校→那经济一不好,这些本来要去或者已经去的选择了私立→私立需要的老师增加 但是觉得B由经济好有25去贵公立并不能直接推出经济不好去私立会增加(因为还有很多其他社会因素啊,贷款啊,文化啊,阶层啊,不是我想太多,我觉得这个逻辑不属于常识范畴,而且题目并未说明这个关系)

就是B需要经过一系列加工才能得出结论,觉得不像正确答案

peterbearpan回复汪二喵
我也是很犹豫A,但看过OoO的解释后,我觉得B正确是因为它直接加强了“学生数会增加”的可能性,进而也就说明对老师的需求量还会增加;而A是说现在s:t高于经济衰退期的,有可能自上次经济衰退后学生数量就已经增加了,等到下一次经济衰退,不一定会有更多的学生补充进来,也就不需要那么多老师。

那这个题的argument 是什么呢
AUCHUI
student/teacher比值不变是出发点。
我要720
我心里面预设的答案是“经济萧条导致读私立学校的学生都来读公立学校。” 但是还真的没拐过B这个弯。。。B感觉就是一个背景,没有支持也没有削弱
