Correct me if I am wrong in my explanation.

*The kind of question this is:* Weaken

*Premise(s):* Marijuana has THC → THC has been found to inactivate herpesvirus (IH) → IH can convert healthy cells into cancer cells.

*Conclusion:* Marijuana can cause cancer.

*What I am looking for:* extra information that we didn’t know about marijuana and its correlation with THC.

*Answer A:* No. That strengthens the argument by showing that scientists had a consensus and the same results.

*Answer B:* Yes. There is information we did not know about marijuana and how it neutralizes THC.

*Answer C:* No. That strengthens the conclusion.

*Answer D:* No. Great, but that is only an “IF.” It would still stand that marijuana causes cancer.

*Answer E:* No. Marijuana is beneficial to cancer patients, but it would still cause cancer for none cancer patients.
