[原创]逻辑Boldface练习题-08投票

sftd

the mistake in A is not only "only", but also "from the first", because the sentence begun with "As..." also play a role in the argument.

But I prefer D, 因为好像没有第一句,论证也是完整的,因为从"As..."那句也可以推出结论.

Are these choices correctly showed? As I understand, A is close to the right answer, but the word "only " is a mistake; for the B choice, actually the first is not the premise, but the fact or evidence. For choice D, "the fact must be true" is also questionable.
Maybe there are nor answer among the choice.

my personal opionion: the fact or evidence can be the premise.

Over the past several years, however, the advance of electronic media, particularly CD-ROMs, online computer services, and the Internet, has made information available to the public electronically without the need for printed materials.

第一句中的Over the past several years表明了这是一个发生在过去的事实。有人认为：“这句话中must be就不太对，谁知道是true 还是不true呢？“我们不论他实际上true or false,我们必须承认它是真的为了下面的因果关系的推论。但我们不能由此判定它就是前提。根据前提的定义：premise   [Show phonetics] noun [C]
an idea or theory on which a statement or action is based:
[+ that] They had started with the premise that all men are created equal.
前提是一个an idea or theory not a fact.
The survival of the publishing industry depends upon the existence of a public who will buy the printed word in the form of newspapers, books and magazines.也是一个是principle.

我的意见是：

简单讲，我认为fact是不可能做premise。因为premise是an idea that you use to support another theory。that idea can be wrong. but fact is that thing happened indeed in the past, it must be true.

举一个例子：
在热恋中，所有男孩子都要给女孩子送花。
我是男孩子且在热恋
所以，我也要送花（后面的但是我没钱，能否像你借钱somethings like that）

在热恋中，所有男孩子都要给女孩子送花。（大前提）
我是男孩子且在热恋（小前提）
所以，我也要送花（结论）

由此看出，前提是一种理论，我认为正确，从而推出有利于我的或我想要得结论。决不是一个事实。至于“在热恋中，所有男孩子都要给女孩子送花。“是不是事实，(例如，就有女追男的吗！） who knows! who care! that is my premise.

这时你可以说：“我们邻居小张就是送的花，结果去年就结婚了。“

这就是一个事实，用来支持你的论证。
实际上8题并不是一个推论性的论证。他实际上是一个因果关系
先描述了一个现象，然后提出了一个因果论证。
希望对你有所帮助。

听你这么一分析，premise 和fact 的区别清晰多了。

我还有个问题，一直很confusing. 就是关于按照谁的逻辑来判断是support, against 和correctly

7. To be accepted as a member at the Brown Country Club, one must have a net worth of over ten million dollars and must not have any connections to the entertainment industry. Robert Chase, the publishing magnate, has a net worth of 5 billion dollars and chase has not financed any Hollywood movies, so he must be accepted as a member at the Brown Country Club.
The two portions in boldface play which of the following roles?
(A) The first is the part of evidence in support of this argument; the second is the conclusion that could not be drawn from all evidence that the argument contains.
(B) The first is the first-evidence that supports this argument; the second is the main point that must be drawn from all evidence that the argument includes.
(C) The first is the one fact of two that argument includes; the second is the conclusion that could be drawn from this passage.
(D) The first is the background that is necessary for this argument; the second is the conclusion that is not drawn only from the first.
(E) The first is the cause that the argument includes; the second is the effect that can be drawn only from this cause.

the reference ans. is A
在a选项中, "in support of" 显然是根据the author's logical thinking, 而之后的“could be drawn"又显然是从旁观者角度出发的，或者讲objective。这两种评判标准是不一样的，好像互相穿插，很头大！

再问个问题，background和fact, premise什么区别

iamnone

不同意,根据PRINSTON的WORKSHOP一个ARGUMENT包括CPA,既前提,结论,和暗含的假设,PREMISE,应该包括, WHATEVER FACT AND IDEA AND PRINCIPLE,ONLY IF IT IS EXPLICITLY INDICATED.
