According to a recent study, advertisements in medical journals often contain misleading information about the effectiveness and safety of new prescription drugs. The medical researchers who wrote the study concluded that the advertisements could result in doctors prescribing inappropriate drugs to their patients.
The researchers' conclusion would be most strengthened if which of the following were true?
- Advertisements for new prescription drugs are an important source of revenue for medical journals.
- Editors of medical journals are often unable to evaluate the claims made in advertisements for new prescription drugs.
- Doctors rely on the advertisements as a source of information about new prescription drugs.
- Advertisements for new prescription drugs are typically less accurate than medical journal articles evaluating those same drugs.
