请教LSAT-Set1-SecIV-2,15,21

2. Creating false marble is an art at which only those with a light hand can excel. Picasso, however, was a great artist, so while he did not have a light hand he could have excelled at creating false marble.
Which one of the following contains a logical error that most closely resembles the logical error contained in the passage?
(A) The police have determined that the murderer left his fingerprints on the knife. Ira’s fingerprints do not match those on the knife, so we can eliminate him as a suspect.
(B) It is true that it is necessary to work hard in order to succeed. However, smith was governor of the state, so it was possible for him to succeed without working hard.
(C) Whenever I eat nuts of any kind I break out in hives. After eating the pie I did not break out, so I know it could not have been real pecan pie.
(D) If the inventory can be sold within the next few months the business can be saved. However, since a sale cannot be concluded quickly, the business will go under.
(E) Only the brave deserve the spoils. Major Wilson has distinguished himself several times for bravery, so surely he deserves the spoils.
答案是B,寻找逻辑错误相似,我只感觉题干中第一句和第二句没什么关系,不知道到底犯了什么逻辑错误?

15. Sven: Trade unions are traditionally regarded by governments and economists as restraints of trade, working against the complete freedom of the economy, but I believe that unions are indispensable since they are often the worker’s only protection against exploitation.
Ravi: I don’t agree. The exploitation of the workers and their work is a normal part of ordinary trade just like the exploitation of natural or other material resources.
Sven and Ravi will not be able to resolve their disagreement logically unless they
(A) define a key term
(B) rely on the opinions of established authorities
(C) question an unproved premise
(D) present supporting data
(E) distinguish fact from opinion
答案是A,请问这题从哪里入手解决?

21. A low-pressure weather system is approaching Plainville; rainfall results from about 70 percent of such systems in the Plainville area. Moreover, the current season, spring, is the time of year in which thundershowers, which sometimes result from low-pressure systems, are most likely to occur in Plainville.
Knowing which one of the following, in addition to the information above, would be most useful for determining the probability that Plainville will have a thundershower soon?
(A) the percentage of thundershowers in Plainville that occur in the spring
(B) the percentage of spring rainfalls in Plainville that are thundershowers
(C) the percentage of thundershowers in Plainville that result from low-pressure systems
(D) whether low-pressure systems in other areas are associated with rainfall
(E) whether Plainville has more or fewer thundershowers each spring than do near by towns.
答案是B,但我感觉C也没问题啊,知道了B的percentage还要再乘个70%,而C的percentage就是结果,乘都不用乘了。

第一题犯了类似权威至上的错误,仅仅因为是某伟人就放弃原则.
第二题是对exploit意思的争议,因为exploit有剥削和利用的意思.sven的意思是利用.而ravin 的意思是剥削.
第三题文章给出了低压带来降雨的概率70%,还有一个附带信息是春季.要求回答的问题是有暴雨的概率,也就是说春季降暴雨的概率.答案C是说降雨中暴雨的概率,既没有说到与气压的关系也没有提到季节因素.
