Question

一道GMAT逻辑题，求解题思路

In 1992, a major newspaper circulated throughout North American paid its reporters an average salary paid by its principle competitors to their reporters. An executive of the newspaper argued that this practice was justified, since any shortfall that might exist in the reporters’ salaries is fully compensated by the valuable training they receive through their assignments.
Which one of the following, if true about the newspaper in 1992, most seriously undermines the justification offered by the executive?
(A) Senior reporters at the newspaper earned as much as reporters of similar stature who worked for the newspaper’s principle competitors.
(B) Most of the newspaper’s reporters had worked there for more than ten years.
(C) The circulation of the newspaper had recently reached a plateau, after it had increased steadily throughout the 1980s.
(D) The union that represented reporters at the newspaper was different from the union that represented reporters at the newspaper’s competitors.
(E) The newspaper was widely read throughout continental Europe and Great Britain as well as North America.
答案是B

Answer 1

削弱题，选B
论点：the executive认为这个水平的薪水是合理的，理由是报社为reporter提供了有价值的培训。
B选项中说此家报社中大部分的reporters都已在那工作10年以上，则培训对他们来说是没有价值的，但其中有一个assuption是这家报社只给新员工提供工作培训，可能有一点争议的地方，个人认为，不知道对不对
A Senior reporters，无关选项 排除
C 自从1980s工资一直再涨和论点论据无关
D union 无关选项
E 无关选项
这样看来，就B选项最合适了，o(∩_∩)o...
