Although exposure to asbe4stos is the primary cause of mesothelioma, a slow-developing cancer,
researchers believe that infection by the SV40 virus is a contributing cause, since in the United
States 60 percent of tissue samples from mesotheliomas, but none from healthy tissue, contain
SV40. SV40 is a monkey virus; however, in 1960 some polio vaccine was contaminated with the
virus. Researchers hypothesize that this vaccine was the source of the virus found in
mesotheliomas decades later.
Which of the following, if true. Most strongly supports the researchers’ hypothesis?
A. SV40 is widely used as a research tool in cancer laboratories.
B. Changes in the technique of manufacturing the vaccine now prevent contamination with
SV40.
C. Recently discovered samples of the vaccine dating from 1960 still show traces of the virus.
D. In a small percentage of cases of mesothelioma, there is no history of exposure to asbestos.
E. In Finland, where the polio vaccine was never contaminated, samples from mosotheliomas
do not contain SV40.

The prairie vole, a small North American grassland rodent, breeds year-round, and a group of
voles living together consists primarily of an extended family, often including two or more litters.
Voles commonly live in large groups from late autumn through winter; from spring through early
autumn, however, most voles live in far smaller groups. The seasonal variation in group size can
probably be explained by a seasonal variation in mortality among young voles.
Which of the following, if true, provides the strongest support for the explanation offered?
A. It is in the spring and early summer that prairie vole communities generally contain the
highest proportion of young voles.
B. Prairie vole populations vary dramatically in size from year to year.
C. The prairie vole subsists primarily on broad-leaved plants that are abundant only in spring.
D. Winters in the prairie voles’ habitat are often harsh, with temperatures that drop well below
freezing.
E. Snakes, a major predator of young prairie voles, are active only from spring through early

Wood smoke contains dangerous toxins that cause changes in human cells. Because wood smoke
presents such a high health risk, legislation is needed to regulate the use of open-air fires and
wood-burning stoves.
Which of the following, if true, provides the most support for the argument above?
A. The amount of dangerous toxins contained in wood smoke is much less than the amount
contained in an equal volume of automobile exhaust.
B. Within the jurisdiction covered by the proposed legislation, most heating and cooking is done
with oil or natural gas.
C. Smoke produced by coal-burning stoves is significantly more toxic than smoke from
wood-burning stoves.
D. No significant beneficial effect on air quality would result if open-air fires were banned
within the jurisdiction covered by the proposed legislation.
E. In valleys where wood in used as the primary heating fuel, the concentration of smoke results
in poor air quality.
