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，帮我解释一下好吗？

According to advertisements, the higher a suntan lotion’s sun protection factor, or SPF, the more protection from sunburn. In order for a suntan lotion to work, however, one has to remember to put it on before going in the sun, put on an adequate amount to cover the skin, and reapply it as needed. Therefore, it really does not matter what SPF a suntan lotion has.
Which one of the following best identifies the error in reasoning made in the passage?
(A) It is unreasonable to assume that the only purpose of a suntan lotion is to provide protection from sunburn.
(B) Because some people get sunburned more easily than others, the fact that there are different SPFs cannot be ignored.
(C) It cannot be concluded that the SPF is not important just because there are requirements for the application of the suntan lotion.
(D) It is unreasonable to assume that all suntan lotions require the same application.
(E) There is no reason to assume that manufacturers are unaware that people sometimes forget to apply suntan lotion before going in the sun.
我选的b，答案是c，怎么理解呢？
谢谢！

第一题是说

要creat mable 就必须是light hand. 某某人是大艺术家，所以即使不是light hand, 也可以creat mable.

B 说要成功就必须努力。某人是governor, 所以不用努力也可以成功。

第二题，至少有两个前人问过。建议search.

还有提个建议，最好把题号写上，便于自己和别人以后查阅。

谢谢，我大致能看明白第一题的意思，只是不明白题干和B怎么就范了同类推理错误了呢？
很不好意思，我的题是在CD上下载的，没寻到题号，所以没写上去
第二道题如果有讨论过给我个link好不好？
