ere that have
been cut off from surface life for millions of years.
These scientists base their argument on the discovery
of living microorganisms in samples of material that
were taken from holes drilled as deep as 1.74 miles.
The scientists’ argument depends on which of the fol-
lowing assumptions?
(A)The microorganisms brought up were of a
species that is related to those previously
known to science.
(B)No holes have been drilled into the Earth’s
surface to a distance deeper than 1.74 miles
(C)The microorganisms did not come from surface
soil that came into contact with the drilling
equipment.
(D) The stratum from which the samples came has
been below the surface of the Earth ever since
the Earth came into existence.
(E) The temperature at the bottom of the holes drilled
was not significantly hotter than that of the
hottest spots on the Earth’s surface.
25. For 20 years all applicants for jobs as technicians at
EquipCorp were required to demonstrate that they could
operate and repair the machinery that was central to
EquipCorp’s manufacturing business. Now, however,
that particular machinery is obsolete, and very different
machinery fills the central role. Therefore, the old
requirement is no longer a useful method for evaluating
whether applicants for jobs as technicians at EquipCorp
have the skills necessary for the job.
Which of the following, if true, most strengthens the
argument?
(A) The machinery that is now obsolete was used by a
large number of manufacturing companies before
it became obsolete.
(B) Among the people already holding jobs as tech-
nicians at Equip Corp, those who are most skillful
at operating the new machinery had been some of
the least skillful at operating the old machinery
(C) Most people applying for jobs as technicians today
have much broader skills than did people applying
for jobs as technicians 20 years ago.
(D) The skills required to operate and repair the
obsolete machinery are useful in operating and
maintaining many other types of machinery at
EquipCorp that are not obsolete.
(E) Much of the machinery that EquipCorp now uses in
manufacturing is very likely to become obsolete
within the next 20 years.
