[size=7.000000pt]The introduction of new drugs into the market is frequently prevented by a shortage of human subjects for the clinical trialsneeded to show that the drugs are safe and effective. Since the lives and health of people in future generations may dependon treatments that are currently experimental, practicing physicians are morally in the wrong when, in the absence of anytreatment proven to be effective, they fail to encourage suitable patients to volunteer for clinical trials.
[size=7.000000pt]Which of the following, if true, casts most doubt on the conclusion of the argument?
- [size=7.000000pt](A) Many drugs undergoing clinical trials are intended for the treatment of conditions for which there is currently noeffective treatment.
- [size=7.000000pt](B) Patients do not share the physician's professional concern for public health, but everyone has a moral obligation toalleviate suffering when able to do so.
- (C) Usually, half the patients in a clinical trial serve as a control group and receive a nonactive drug in place of the drugbeing tested.
[size=7.000000pt] {D} An experimental drug cannot legally be made available to patients unless those patients are subjects in clinical trialsof the drug.
