Dear Mike

:) thanks for reply. Now pl suggest me something.

Initially even i thought of the same answer what you have suggested, but further changed my decision when in conclusion I saw the word " this vaccine." I understood it as to find the support only for that particular 1906 contaminated vaccine as only responsible for the outbreak. Whereas your answer no effect no cause make me to understand conclusion as all vaccines are causing issue.Pl suggest
Regards, Sid

Dear Sid,
I'm happy to respond. :-) Are you aware that this request is not very clearly written? I believe I understand what you are asking. It would be excellent practice for you to strive to have all your writing on GMAT Club adhere to the high standards of GMAT SC. Resist the urge to be casual and efficient. Every single thing you do here can serve as practice for your GMAT, and excellence demands no less than that.

Here is the argument again:
Although exposure to asbestos is the primary cause of mesothelioma, a slow-developing cancer, researches 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?

So, yes, the conclusion is about this one and only this one vaccine, the 1960 polio vaccine that was contaminated with SV40.

This doesn't not change anything about my analysis above. Choice (C) only repeats what we already know. It reinforces evidence that was already stated, and makes absolutely no link to mesothelioma. By contrast, in an argument that P causes Q, the evidence "no P, no Q" is very powerful support, and that's precisely what choice (E) provides.

Does this make sense?
Mike :-)

E is the best answer, because when the cause is absent (contaminated polio vaccine), the effect (presence of SV40 virus) is also absent. Now if I could only digest these hard to understand CR questions within 2 minutes. :(

Which of the following, if true, most strongly supports the researchers' hypothesis?

a) SV40 is widely used as a research tool in cancer laboratores.

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.


Please explain when choosing your answer.



Applying what i learnt from CR bible book:
One of the ways of strengthening a Cause-Effect relationship(C->E) is saying !C->!E

Coming back to the question, we have to strengthen contaminated vaccine was responsible for SV40 virus
(E) says- no contaminated vaccine hence no SV40 virus(!C->!E form)
