Veterinarians generally derive some of their income from selling several manufacturers’ lines of pet-care products. Knowing that pet owners rarely throw away mail from their pet’s veterinarian unread, one manufacturer of pet-care products offered free promotional materials on its products to veterinarians for mailing to their clients. Very few veterinarians accepted the offer, however, even though the manufacturer’s products are of high quality.
Which of the following, if true, most helps to explain the veterinarians’ reaction to the manufacturer’s promotional scheme ?
Most of the veterinarians to whom the free promotional materials were offered were already selling the manufacturer’s per-care products to their clients.
The special promotional materials were intended as a supplement to the manufacturer’s usual promotional activities rather than as a replacement for them.
The manufacturer’s products, unlike most equally good competing products sold by veterinarians, are also available in pet stores and in supermarkets.
Many pet owners have begun demanding quality in products they buy for their pets that is as high as that in products they buy for themselves.
Veterinarians sometimes recommend that pet owners use products formulated for people when no suitable product specially formulated for animals is available.
情景：兽医一般会从买周边产品处赚点小钱。由于很少有宠物主人会扔掉邮件，所以一个制造商就夹了一些材料在邮件中。但，虽然这个材料质量很好，不过还是几乎没有兽医接受这种提案。
推理：注意本题的问题。本题直接问了哪一项可以解释这个兽医不接受提案的现象。而按照正常逻辑来说，即：
前提：促销材料免费且产品质量很好
结论：兽医接受提案
显然地，前提是原因，结论是结果。本题为因果推理。
选题方式：选项必须能断掉因果之间的关系。
选项分析：
A选项：大部分被提供免费促销材料的兽医已经正在给他们的客户卖周边产品了。本选项和因果逻辑无关，我们的推理点是，“材料很好”推出“接受提案”。无论兽医是否正在卖别的产品，他都可以再接受卖个新产品嘛。
B选项：特殊促销材料被用来作为通常促销材料的补充而非代替。本选项和推理无关。
C选项：Correct. 不像很多兽医卖的竞品，这个制造商的产品也在宠物商店和超市被提供。显然，这可以断掉“材料很好”推出“接受提案”间的关系，即，纵然很好，但由于到处都有卖的，兽医也卖不出去，自然就不会接受提案了。
D选项：很多宠物拥有者对于宠物产品的质量要求已经和他们对给自己的东西的质量要求相同了。由于制造商的产品本来就很好，所以这样的要求反而会加剧兽医应该接受制造商的产品这一说法。
E选项：兽医有时会建议在没有适合给动物的产品提供时，可以用给人的产品来替代。本选项和推理无关。
C. 所以推广了之后，这个钱兽医就赚不到了，人们就会去超市买
