1、gmat题目求解答！

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. Profits 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’ profits.

(B) Most of the people who bought Dietz’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 have brought in significantly 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 five years, there was a steep, industry-wide decline in sales of canned tuna.

2、怎样取消GMAT的大学广告邮件

本来考试的时候一不留神选了Yes 现在邮箱被塞满了呀各种大学的邮件 求取消方法

3、参加过GMAT考试后，邮箱里经常有国外商学院的录取委员会发来的邀请邮件，有些不知名，有些是MIT类的牛校。

不必理会，应该也就是广告吧，群发邮件啦，不必在意。

GMAT是GraduateManagementAdmissionTest（研究生管理科学入学考试）的简称。美国、英国、澳大利亚等国家的高校都采用GMAT考试成绩来评估申请入学者是否适合于在商业、经济和管理等专业的研究生阶段学习，以决定是否录取。

考试当日，您有3小时30分钟的时间去完成GMAT考试的四个组成部分：分析性写作、综合推理、定量推理和文本逻辑推理。

您的GMAT成绩取决于多个因素，包括您回答的试题数量、回答是否正确、试题难度，以及每个试题的其他统计特性。

4、注册GMAT账号后收到一些商学院发的广告性质的邮件，需要回复吗？

貌似还是不错的学校
