SDCAR2010【逻辑入门】（一）Arguments

Thanks for sharing such insightful viewpoints.
However, I can't really agree and understand with the example LZ to explain some arguments don't have signals:

2) Becasue every milk product from Three Deers must be recalled, these products contains melamine which could lead to renal failure.
Personally, I feel the reason is not sufficient to make the conclusion, since  "products contains melamine which could lead to renal failure" couldn't be the only reason. Thanks!

Of course there are many reasons that could lead to the recall of diary products. But that's not the point here. The issue here is that if you see two statements and no indicator, which one is more likely to be the premise and which one is more likely to be the conclusion.

Using the "plug in" method, you can quickly figure out which is which. As to the legality or logic of the combined statement thus obtained, that's another story!

Of cause there are many reasons that could lead to the recall of diary products. But that's not the point here. The issue here is that if you see two statements and no indicator, which one is more likely to be the premise and which one is more likely to be the conclusion.

! I misunderstood the major point here! Some premises and conclusions can be reversed and some are not,right? What do you mean by legality or logic of the combined statement thus obtained?

I mean if the combined statement has flaws . . .

Sdcar NN, i just wonder whether there is always a conclusion and some premises in every argument. it seems that in some sort of questions, such as weaken, support, assumption, there must be a conclusion in the argument. but when it comes to the Must-be-true, for instance, it seems that the argument just present us a set of fact or a thread of something.

Thx in advance!

BTW, is the question below a Must-not-be-true question without a conclusion?  Thx!

Junior biomedical researchers have long assumed that their hirings and promotions depend significantly on the amount of their published work.  eople responsible for making hiring and promotion decisions in the biomedical research field, however, are influenced much more by the overall impact that a candidate's scientific publications have on his or her field than by the number of those publications.
The information above, if accurate, argues most strongly against which of the following claims?
A. Even biomedical researchers who are just beginning their careers are expected already to have published articles of major significance to the field.
B. Contributions to the field of biomedical research are generally considered to be significant only if the work is published.
C. The potential scientific importance of not-yet-published work is sometimes taken into account in decisions regarding the hiring or promotion of biomedical researchers.
D. People responsible for hiring or promoting biomedical researchers can reasonably be expected to make a fair assessment of the overall impact of a candidate's publications on his or her field.
E. Biomedical researchers can substantially increase their chances of promotion by fragmenting their research findings so that they are published in several journals instead of one.

If there is an argument, there must be a conclusion.

For must-be-true type of question, sometimes you have a list of facts, not an argument. Therefore, no conclusion or premise.
