Although exposure to asbestos is the primary cause for mesothelioma, a slow-developing cancer, researchers believe that infection by the SV40 virus is a contributing case, since in the US 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 toll 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 mesotheliomas do not contain SV40.
[Reveal] Spoiler: OA

E
Conclusion - vaccine was the source of the virus found in mesotheliomas
Strengthen - The point that where vaccine was not contaminated by the virus, mesotheliomas samples do not contain SV40

Although exposure to asbestos is the primary cause for mesothelioma, a slow-developing cancer, researchers believe that infection by the SV40 virus is a contributing case, since in the US 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.

The conclusion is that the SV40 in the vaccine is the source of the mesothelioma.
Which of the following, if true, most strongly supports the researchers' hypothesis?

A. SV40 is widely used as a research tool in cancer laboratories. Not relevant
B. Changes in the technique of manufacturing the vaccine now prevent contamination with SV40. Doesn't demonstrate that SV40 in the vaccinate could have caused the mesothelioma.
C. Recently discovered samples of the vaccine dating from 1960 still show traces of the virus.Shows that the virus was present but not that it caused mesothelioma
D. In a small percentage of cases of mesothelioma, there is no history of exposure to asbestos. This could weaken the argument.
E. In Finland, where the polio vaccine was never contaminated, samples from mesotheliomas do not contain SV40.
Where there was no SV40 contamination, mesotheliomas were not linked to SV40 (rather something else, like asbestos)
