4. 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 hat 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 manufacturer are unaware that people sometimes forget to apply suntan lotion before going in the sun.

是削弱题吗？

这种题型是让你找出题干论证过程的错误，我没把它归入weaken，归入identify题了（是根据xdf的老师归的）。

这句话我核对了一下原题，"hat spf"应该是"what spf"，意思可以理解为“因此，suntan lotion含多少的spf值就不重要了。”

不贴答案可真不好
答案是c
最后一句话的意思是，什么样的spa就没有关系了
这个结论和原文无关，所以原文的逻辑是错误的
举个例子
用奶粉冲牛奶，放的越多就越香。你能从这里面得出结论说是奶粉就没有关系了吗，当然不是咯，我还是喜欢蒙牛的，呵呵，伊犁的味道淡啊

炒蛋的例子很生动嘛。哈哈。忽然很想念光明了。

这其实是一个典型的说某东东的A特性有用（比如说常常抹就防晒）就否定B特性（其实本质特性）没用。

就算你完全按指示抹，SPF不够指还是不能防晒呀。

呵呵，谢谢大家
炒蛋和蒙牛就要做牛人哦

，明天开始我也喝蒙牛！！

B为什么不对呢？我理解B是说，每个人的抗晒能力是不同的，因此即使按照同样的方法使用防晒霜，含不同SPF的防晒霜的防晒能力还是不同的，因此SPF不能被忽视，感觉B和C都对啊

我开始也选b 可是仔细想想原文问的是论证结构的error 并不是让我们去削弱这个结论所以b是错的

Spot the question type: Method of the reasoning - Flaw.

Higher SPF in SL, More P from Sb

So, The kinds of SPF is not necessary for SL.

1. Falsely to assume that if it is SPF, It must be worked the same.

2. Falsely to assume that a necessary condition is not important.

let us dive into the answers.

A. Its not really relevant to the argument.

B. It is true that the this option " does " weaken the argument; however, we are discussing the " flaws " within the argument. - Contenders

* Reason why it could serve as the weakening option: if different SPFS exist, it must be true that different SPFS be catering to the different level of the sunburn. If so, then it must be true that SPFS truly does matter.

C. Correct answer. Truly discuss about the flaw committed

D. Actually, the question is falsely assumed that all suntan lotion does not require the same application

E. Not really relevant

D.
