More than the answer I am trying to get my concept right !!!!!An ingredient in marijuana known as THC has been found to inactivate herpesviruses in experiments. In previous experiments researchers found that inactivated herpesviruses can convert healthy cells into cancer cells. It can be concluded that the use of marijuana can cause cancer.
Which one of the following, if true, most seriously
weakens the argument?
(A) Several teams of scientists performed the various
experiments and all of the teams had similar
results.
(B) The carcinogenic effect of THC could be
neutralized by the other ingredients found in
marijuana.
(C) When THC kills herpesviruses it weakens the
immune system, and it might thus diminish the
body's ability to fight other viruses, including
viruses linked to cancers.
(D) If chemists modify the structure of THC, THC
can be safely incorporated into medications to
prevent herpes.
(E) To lessen the undesirable side effects of
chemotherapy, the use of marijuana has been
recommended for cancer patients who are free of
the herpesvirus.
First the questions states "Which one of the following, if true, most seriously
weakens the argument? "
So here as the questions states all are true none of the options are far fetched.
Had the question been Which one of the following, most seriously weakens the argument?, wouldn't option B be far fetched as nothing is being said about any counteractive ingredient in marijuana. Correct me if I am wrong
Second I fell for option C, the reasoning behind this is TMH only weakens the immune system but something else that is carciogenic is making use of this. SO TMH in effect is not carciogenic
