大全-2-8 和大全-2-16.在两 个混淆选项中，我为何总选了错的那个

16. Advertiser--The revenue that newspapers and magazines earn by publishing advertisements allows publishers to keep the prices per copy of their publications much lower thanwould otherwise be possible. Therefore, consumers benefit economically from advertising.

Consumer--But who pays for the advertising that pays for low-priced newspapers and magazine. We consumers do, because advertisers pass along advertising costs to us through the higher prices they charge for their products.

A. By alleging something that, if true, would weaken the plausibility of the advertiser's conclusion

B. By questioning the truth of the purportedly factual statemnet on which the advertiser's conclusion is based.

在两 个混淆选项中，我为何总选了错的那个。

看看这此例。因为消费者的反驳中，有一个问句，所以我选有B，B说有质问之意。我左看右看，其实AB选项差不多，差别在哪呵.到这种关键时刻，脑袋就晕

8.Teenaggers are often priced out of the labor market by the goverment-mandated minimum-wage level because employers cannot afford to pay that much of extra help. Therefore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.

Which of the following, if true, would most weaken the argument above

A. Since 1960 the teengage unemployment rate has risen when the minimum wage has risen.

B. Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

D.The teenage unemployment rate rose more quickly in the 1970's than it did in the 1960.

我好不容易排除了其它错误选项，但 我的思路是—选A比B 好，因为当最低工资已提高，儿童失业率也在提高，这样说不是比B 说保持最低工资，但失业率仍高更具削弱性吗，况且C说70年代的失业率比60年代增长得更快，似乎更具削弱性。我不明白，正确答案为何是B。ABC为何B 是对的。AC更具杀伤力呵。

在这里讨论，收获真大，很多想不通的，经高手指点，就获真经

UP UP UP

你上个帖子我也跟了,就是那个SECTION 2-6, 现在我仍然要UP UP,错的一样噎,我们的思路都........

2－16

我认为选A。weaken the plausibility of the advertiser's conclusion，即 consumers benefit economically from advertising

Consumer并未如答案B所述，置疑Advertiser所陈述的论据“The revenue that newspapers and magazines earn by publishing advertisements allows publishers to keep the prices per copy of their publications much lower thanwould otherwise be possible.”

2－8

原文的结论是，若降低最低工资，儿童失业率会停止增长

答案A，最低工资上涨，儿童失业率增加。我认为这可以是原文的一个推论“Teenaggers are often priced out of the labor market by the goverment-mandated minimum-wage level because employers cannot afford to pay that much of extra help”雇主就是因为最低工资的要求，而不肯雇佣生产能力并不强的童工

答案C，我认为没有比较失业率与最低工资的关系，无关

所以相对而言，应该是B

我的思路：选项A，并非削弱。从“提高最低工资>儿童失业率提高”，不能推出逆命题“降低最低工资>儿童失业率降低”

选项C，70年代的失业率比60年代增长得更快，这可能是其他原因导致的，也就不能削弱

对于选项B，我认为它表达了一个趋势（工资不变，失业率升高），使命题中的结论（降低工资，即可使失业率稳定）不能充分成立。
