Private industry is trying to attract skilled research
scientists by offering them high salaries. As a result,
most research scientists employed in private industry
now earn 50 percent more than do comparably skilled
research scientists employed by the government. So,
unless government-employed research scientists are
motivated more by a sense of public duty than by their
own interests, the government is likely to lose its most
skilled research scientists to private industry, since none
of these scientistswould have problems finding privatesector
jobs.
Which one of the following is an assumption on which
the argument depends?

(A) Government research scientists are less likely to
receive acknowledgment for their research
contributions than are research scientists in the
private sector.
(B) None of the research scientists currently
employed by the government earns more than
the highest-paid researchers employed in the
private sector.
(C) The government does not employ as many
research scientists who are highly skilled as does
any large company in the private sector which
employs research scientists.
(D) The government does not provide its research
scientists with unusually good working
conditions or fringe benefits that more than
compensate for the lower salaries they receive.
(E) Research scientists employed in the private sector
generally work longer hours than do researchers
employed by the government.
