请问大牛fyhllj10月逻辑机经一道

kathy72

62. 某处某种房子发现其树是某年的,因为没有别的房子早于那年,所以那房子建的最早,问assumption
我的答案:树砍了后不会storage.

fyhllj评价: 不同意。应为那房子没有在重见过。

请问fyhllj:
为什么"树砍了后不会storage"不是假设? 如果将其取非, 树被砍后放置了一段时间, 这期间有别的树被建成了房子, 不是削弱了原文的结论吗?

不过, "那房子没有被重建过" 应该也构成假设. 这两个选项是同时出现的吗?

fyhllj

这个题是假设，树和房子是同一年见得，且两者共存共荣到今天。
题目中提供的事实是那棵树的年龄最老，老于周围所有的房子，这是题目中提供的事实必须承认。
因此即使树砍了后不会storage取非，仍然无法推翻那棵树的年龄最老，老于周围所有的房子。所以不是架设。

而如果房子有在重见过，例如就在调查的前一年，则可以否定所以那房子建的最早的结论。

我没有在考试中遇到这道题，不知其选项如何，但是原作者的选想是错误的。

我所提供的答案是我自己假设的。共在做题诗参考。

Personally, I do not like the idea of using CR JJ in Chinese. I always think that every word in a CR question is important. The translation itself might very likely distort the meaning. You guys already have hundreds of question...

I agree with Kathy. If the wood was put into storage for a while before the house was built with it, it is very likely that some other houses might have been built during that period with wood less old. For example, if I build a house tolday with stored wood from 200 years ago, it does not mean that my house is older than houses built 50 years ago with wood of the same time. Right?

If I am such NN as Mindfree, I would remember cr jj in English, but.......

mindfree

I cannot remember mine well enough either...I just feel like it is not as useful to do CR jj as math jj.
