关于“无关”概念的举例~

polizun

我也搜过相关的内容，似乎解答的回帖的人很少啊。。就还是熏衣紫的所说的：无关有以下几种类型:

1) 无故牵扯集合以外的样本;

2) 无故将完整的集合分成子集加以比较;

3) 无故牵扯提干以外的时间范畴;

4) 直接与结论无关.
麻烦哪位大侠举个例子~~万分感谢~~

偶自己先举一个，就是不太确定啊
OG12-80
Products sold under a brand name used to command
premium prices because, in general, they were
superior to nonbrand rival products. Technical
expertise in product development has become so
widespread, however, that special quality advantages
are very hard to obtain these days and even harder to
maintain. As a consequence, brand-name products
generally neither offer higher quality nor sell at higher
prices. Paradoxically, brand names are a bigger
marketing advantage than ever.
Which of the following, if true, most helps to resolve
the paradox outlined above?
(A) Brand names are taken by consumers as a
guarantee of getting a product as good as the
best rival products.
(B) Consumers recognize that the quality of
products sold under invariant brand names can
drift over time.
(C) In many acquisitions of one corporation by
another, the acquiring corporation is interested
more in acquiring the right to use certain brand
names than in acquiring existing production
facilities.
(D) In the days when special quality advantages
were easier to obtain than they are now, it was
also easier to get new brand names established.
(E) The advertising of a company’s brand-name
products is at times transferred to a new
advertising agency, especially when sales are
declining.

个人认为BDCE都无关。。要是将那四个“无关”类型分配的话，比如B讲的是没有牌子的商品，那就归为 2) 无故将完整的集合分成子集加以比较 或是 1) 无故牵扯集合以外的样本 C讲的是公司并购时更看重牌子，应该就是 1) 无故牵扯集合以外的样本 D的话讲的是产品优势容易得到和保持的时候的事，就暂且归为 3) 无故牵扯提干以外的时间范畴 好了。。说真的，这类型的无关似乎不太多啊。E的话说转到另一个广告商，应该就是 4) 直接与结论无关 或是 1) 无故牵扯集合以外的样本。
我怎么觉得1）和4）没什么区别呀，而且几乎所有无关都可以归为 4）直接与结论无关 吧。。。求助~~或是说说大家是怎么判断无关的~~多谢啊啊~不想让帖子沉啊~~
