A and B are both mentioned in the article. A is a situation in a sample and B in a population. We know that the sample statistics can never surely represent the population and vice versa. If sample and population can reflect the real situation each other, we can assume a sequence of facts that one person argue that all the computers in the PC World are ill-functioned with the reason that the computer he bought does not work properly. Obviously, such evidence is not sufficient.

　　C: exchange the concepts

　　The relationship of A and B in the article is just that there are some similar points that A and B present at the same time. However, if such a reasoning based on some similar points is right, we can presumptuously assume a fact that the professor in math department and a computer can all calculated very complex formula so they two are all eligible for the assessment of Nobile price. Obviously, any one with common sense will disagree such a ridiculous reasoning.

　　结尾，

　　End:

　　To sum up, the argument above lacks credibility and the reasoning of the arguer fails to support the conclusion. Admittedly, however, if the faults in the argument are corrected, more evidence is given and the existence of A and B is verified, the whole reasoning the argument would be more strong.

　　还应该有一段是驳斥别的东西，我觉得不太好，没写出来，考试时是临场发挥的。
