which of the following most logically completes the argument?

A significant number of Qualitex Corporation's department heads are due to retire this year. The number of employees other than current department heads who could take on the position of department head is equal to only about half of the expected vacancies. Oualitex is not going to hire department heads from outside the company or have current department heads take over more than one department, so some departments will be without department heads next year unless Qualitex_______________.

D:reduce the average number of employees per department

E: reduce the number of its departments

既不能从外面引人, 也不能合并部门

答案选E, 我最后选了D

E 给人感觉有合并之嫌. 比如说原来3个部门, 现在合并成2个, 也就减少了number of its departments.

D, 部门人员减少, 我觉得也有点别扭, 但好象只有它和原文条件不冲突.

大家怎么看?

the article argues that the leaders are less than the needs of different departments , and ask you how to deal with the problem . the company however excludes two methods such as employ heads from outside and let current head in charge of more than two departments . that is to say you can't solve the problem by changing the people .therefore , by reduce the number of the departments , the company could eliminate the expected vanacies .

the choice D is incorrect , because it can't fill the vanacies , means that some departments still need heads .

be more careful , and deeply understand the reasoning and meaning of the passage , i believe you can crack the GMAT .
