总是被这种题型里面的那个迷惑选项绕进去！！！大家帮我看看我想得对不对呢？其实这种题目我做的时候还是有点容易错选另一个。
34. A year ago, Dietz Foods launched a yearlong advertising campaign for its canned tuna. Last year Dietz sold 12 million cans of tuna compared to the 10 million sold during the previous year, an increase directly attributable to new customers brought in by the campaign. Pro?ts from the additional sales, however, were substantially less than the cost of the advertising campaign. Clearly, therefore, the campaign did nothing to further Dietz’s economic interests.
Which of the following, if true, most seriously weakens the argument?
(A) Sales of canned tuna account for a relatively small percentage of Dietz Foods’ pro?ts.
(B) Most of the people who bought Dietz’s canned tuna for the ?rst time as a result of the campaign were already loyal customers of other Dietz products.
(C) A less expensive advertising campaign would have brought in signi?cantly fewer new customers for Dietz’s canned tuna than did the campaign Dietz Foods launched last year.
(D) Dietz made money on sales of canned tuna last year.
(E) In each of the past ?ve years, there was a steep, industry-wide decline in sales of canned tuna.
答案E。这类题目我总是会错选B这种答案。是不是要明确题目里面讨论的是campaign和canned tuna销量的关系，从而涉及interest？所以，other DIETZ product就是无关因素了？？ 但是我总是会想，other D 也是D的利润里面的一部分。它能增加D的其他产品的销售，就不能仅仅只看canned tuna的销售量了？
原谅我的凌乱~每次碰见这种题型就瞬间凌乱了~~排除三个之后，总会选剩下那个错的。。。求救啊~ |
