标题: 帮忙看一道笔考逻辑题

Many television viewers own videocassette recorders (VCR’s). Companies that advertise on television complain that VCR ownership hurts their business, since a VCR makes it possible to view television programs without watching the commercials. Indeed, two-thirds of those who tape programs on a VCR edit out the commercials when viewing the programs.

Which of the following, if true, would most strengthen the companies’ complaint that VCR ownership is currently hurting their business?

(A) The methods for determining audience size, which in turn determines charges for advertising time, count households that are merely recording a program as households that are watching it.

(B) VCR manufacturers who advertise on television would themselves suffer the damage, if any, to advertisers’ interests that is caused by VCR’s.

(C) There are VCR’s that are in the early stages of development that will automatically edit out commercials during the recording process.
(D) Those who tape programs on VCR’s, but who do not edit out commercials when viewing the programs, tape more often than those who do edit out the commercials.

(E) Some television commercials are as entertaining or informative as the programs they interrupt.(A)

这题挺绕的。

首先，文章的结论是：VCR的存在hurt作广告的business。所以答案一定是business被hurt了。先排除BDE
B：...if any...如果有伤害的话，VCR的生产商也会被damage。没有确定说business被hurt了
D：tape多少的比较，无关
E：广告本身是否有趣，无关

再来看AC。其实一开始的时候，我觉得C也像加强。因为C加强了VCR剪掉广告的强度。但是再读一次文章，发现：
1.VCR能剪掉广告，其实是文章给出的背景信息
2.文章问的是hurt business，而不是说广告是否达到了其效用。就算C中VCR能自动剪掉广告，不等于就对做广告的公司造成了hurt，最多是广告不起效用而已

而A：不看广告的人也被计算在audience之内，来向做广告的公司收取广告费－－这里不看广告就对business做出了实质的hurt－－cost提高了。
