Choice A

I eliminated A due to the use of the quantifier: many = some = could be just 1 how can we ignore that in this case?

Hello @Meredith,

Let's break down the problem.

Premise: Patients will not be harmed by consuming safe herbs
Premise: Patients might be helped by herbs

Conclusion: Advocates of herbal remedies should be allowed to prescribe them

Here is why the quantifier "many" doesn't disqualify answer choice A. The doctor's argument relies upon the premise that "since their patients will not be harmed." Answer choice A gives an example of harm that can befall many patients. No matter how many patients this affects, it attacks a key premise from the argument. "Many" actually weakens the doctor's argument more than would "some" or "a few." We don't have to ignore the quantifier, we just do not need every single patient to be harmed in order to weaken the argument.
