如題

因果关系中，排除可能导致果的其他原因。因为题目中要support的就是：原因导致结果。那么支持应该说就是这个原因导致的。所以把其他原因排除掉。

感謝2樓!
那以下面這題為例:

A
year ago, Dietz Food launched a yearlong advertising campaign for its
canned tuna. Last year, Dietz sold 12 million cans of customers brought
in by the campaign. Profits form the additional sales, however, were
substantially less than the cost of the advertising campaign. Clearly,
therefore, campaign did nothing to further Dietz food economic
interests.

A. Sales of canned tuna account for a relatively small percentage of Dietz Food’s profit.

B.
Most of the people who bought Diefdtz’s canned tuna for the first time
as a result of the campaign were already loyal customers of other Dietz
products.

C.
A less expensive advertising campaign would brought in significantly
fewer new customers for Dietz’s canned tuna did the campaign Dietz’s
launched last year.

D. Dietz made money on sales of canned tuna last year.

E. In each of the past five years, there was a steep. Industry-wide declines in sales of canned tuna.

答案是E且E為排除他因

在這題中的"其他原因"是甚麼呢

如果答案为E，那么此题是削弱，不是排除他因，而是指出他因。他因就是：不是campaign本身有问题，而是大势不好。

難怪當初越看越奇怪
謝謝NN的指點
