题型:单项选择题

Armtech, a temporary-employment agency, previously gave its employees 2. 5 paid vacation days after each 700 hours worked. Armtech’s new policy is to give its employees 5.0 paid vacation days after each 1,200 hours worked. Therefore, this new policy is more generous to Armtech employees in giving them more vacation days per hour worked than the old policy did.
Which of the following is an assumption on which the argument depends

A.Most current Armtech employees approve of the company’s new vacation policy.

B.A few Armtech employees leave the company before having worked 700 hours.

C.Most Armtech employees were not aware that the company planned to change its vacation policy until after it had already done so.

D.A significant portion of Armtech employees stay with the company long enough to work for 1,200 hours.

E.(E) Armtech’s new vacation policy closely matches the vacation policies of competing temporary employment agencies.
