10.Cable-television spokesperson: Subscriptions tocable television are a bargain in comparison to "free"television. Remember that "free" television is not reallyfree. It is consumers, in the end, who pay for thecostly advertising that supports "free" television.

Which of the following, if true, is most damaging to theposition of the cable-television spokesperson?



BSubscriptions to cable television include access to some public-television channels, which do notaccept advertising.

DFor locations with poor television reception,cable television provides picture quality superiorto that provided by free television.

ECable-television subscribers can choose whichchannels they wish to receive.

这道题选D木有问题,小鹿又开始钻错误选项解释的牛角尖了,这次的疑问是在错误选项BE的解释

B的OG解释The fact that cable television subscriptions include access to advertising-free public-television channels does not weaken the argument that “free” television is not free.

首先小鹿对于B的理解是:极弱的strengthen

分析题干,Cable电视的发言人的argumentpoint在于:“Subscriptions to cable television are a bargain in comparison to "free" television.”那么得到这个point的原因在于消费者需要支付free电视的广告费。而B选项,cable电视可以收到没有广告的频道,刚好对应了这个发言人得到结论的原因,但因为是“include”“some”,所以是极弱的加强。

可是OG的解释,不但没有说这个极弱的加强作用,最让我不理解的是,OG说这个事实并没有削弱“free television is not free”这个argument。我觉得point有些偏移,就算削弱也应该削弱“bargain”这个argument,为什么说没有削弱“free television is not free”这个argument呢?

综上,2个疑问点:B选项是否有微弱的加强作用;B中“cable电视能收到没有广告的频道”和“free television is not free”有什么联系?

E的OG解释Television viewers who do not watch cable channels have a choice as to which channels and programs they view. For example, they could watch channels with no advertising. So this information does not differentiate cable-television viewers from “free”-television viewers.

首先小鹿对于E的理解是:极弱的strengthen

题干分析同上。而E选项,人们可以选择没有广告的频道,和B选项实际是一样的,所以是极弱的加强。


可是OG的解释,前半部分都非常好,可最后一句从“So”开始让小鹿丈二和尚摸不着头脑~~除了没有提到加强作用,最让我不理解的是,从哪看出来cable电视的viewerfree电视的viewer没有区别了?cable电视的viewer可以选择不看有广告的频道,free电视的viewer也行嘛?

综上,2个疑问点:E选项是否有微弱的加强作用;E中“cable电视viewer可自由选择频道”和“看两种电视的viewer没有分别”有什么关系?

小鹿啊~我不太赞同你以学习SC的方法来分析CR题目的错误选项哟~特别是这种weaken题~

你拿一些weaken题目的错误选项来看过之后就会发现,weaken题目的错误选项一般都会有几种错法。要不是无关,偏离argument的核心讨论,或者是干脆strengthen。
其实无关和偏离有点像,但是我感觉无关更像是出现不会涉argument关键讨论的new info。
而偏离的话一般还是会出现argument中主要的对立面,就像这题的cable TV和free TV。只不过讨论的内容偏离,达不到weaken的效果。
strengthen的话就很容易理解了~

先分析题目:
conclusion:Subscriptions to cable television are a bargain in comparison to "free"television.
Premise:consumers pay for the costly advertising that supports "free" television.

要weaken conclusion,像是这题的B、E选项。
B
Subscriptions to cable television include access to some public-television channels, which do not accept advertising.
这里是个无关选项,因为argument中的draw the conclusion在于有advertising会导致消费,不bargain。而没有advertising是不能weaken advertising最终导致不bargain的结果的。

E
Cable-television subscribers can choose which channels they wish to receive.
这里我认为这个还是一个无关选项。我暗自认为小鹿应该在做这个选项的时候给他加了一个assumption,就是有的channels没有advertising,而有的channels有。这个选项的错误点跟B其实是一模一样的。跟题目argument从premise到conclusion的这个flow没有影响。所以也没有weaken作用。

小鹿,你再跳出来看一下就会发现其实你想复杂了~

此贴暂停喽~teddy说的对,这样学习逻辑确实效率低,这种钻OG牛角尖的学习方法不一定有意义,反而可以每道题把削弱、加强、解释、假设都自己出题自己做一遍~
