gwd-12-11 偶碰到的一道难题

mindfree, you are my model to pursue a wonderful career, but i still disagree with what you have said.

first of all, B is irrelevant to the question, because the argument does not concern periods when the Vargonian economy has been strong, all of the argument talks about the periods of recession, so does C and D, (before the last economic recession, privately funded schools ).

A is the best choice, because "current student-teacher ratios not be exceeded" , the last sentence in the argument .if A, that is,

1. The current student-teacher ratio at Vargonia’s government-funded schools is higher than it was during the most recent period of economic recession, then A strengthen the argument.

it is my private idea, please talk about it further more...

thank you, mindfree

a 是无关项，用当前的比率与过去的比，说明不了任何当前比率在未来变化的趋势，无论它是高是低。

就像说:我们现在的生活水平是这个样子的，现在由于有了什么什么原因，我们的生活水平在将来一定会提高。让你加强。

你说我们现在的生活比过去好，或比过去差，都不起作用

这里我始终认为最有可能的答案是B OR E,但大家对E好像都不屑一顾，郁闷！

E说的是上回经济衰退，政府关闭了好些学校。但是，注意现在条件变了，通过了一个什么法律旨在刺激学生入学，又要保证学生与教师比例不变，那现有的师资是不是很可能因为以前关闭了学校而变得不够啊。

我认为这起到了正向加强的作用。

B 其实也挺好，但就是还需进一步假设，在经济衰退中，这25%中回到公立学校的人数足以改变现有教师学生比例，但这是不一定的。

也可能我的想法在钻死胡同，希望NN指正。

呆板彻底

感觉此题逻辑不清晰。

顶上来应该是a对

现在的学生：老师比最近的萧条时期大，也就说明现在老师是缺乏的，所以不用担心找不到工作

明显ets是不允许自己加假设的

其实，a和c的实质是一样的，都是再说现在（一种结论要求的现象），而没有提供其他可对未来产生影响的信息。

所以 是b

I choose B, though it requires some common sense to make an assumption

I think neither A or C is relevent to the original argument. Since the conclusion is about the future trends, (the availability of jobs...will), and both A and C just provide a comparison between now and past, which cannot be used to strengthen or weaken any future trend.

To some degree,  A and C commit the same logic fallacy, and therefore should be excluded.

我在a,b中犹豫，相对而言，倾向于b！
