manhattan模考上的一道逻辑难题！！求各位牛牛指教！！！

Some public health advocates have become concerned that directly advertising prescription drugs to consumers is likely to cause some patients to pursue certain medications that may be inappropriate for their individual health situation. However, marketing to consumers should not be limited as long as physicians also continue to be educated about such medications, because a physician's prescription is still required in order for patients to obtain these drugs.

Which of the following facts would most directly address the concern articulated by the public health advocates?

		After a certain number of years, prescription drugs lose patent protection and other companies can then manufacture and market generic forms of the drugs.
		Consumers can now find technical drug information on the Internet, information that previously would have been available only to physicians.
		Physicians are also exposed to prescription drug advertisements that are directed toward consumers.
		Physicians are not susceptible to pressure from patients in determining appropriate courses of treatment.
		Fewer than 15% of patients are likely to remember and ask by name for specific drugs that they see advertised in magazines or on television.
