Final answer:
The statement is false; the Tuskegee Study failed to adequately cover the ethical principles of autonomy, beneficence, nonmaleficence, and justice, notably infringing upon participants' autonomy by not providing informed consent.
Step-by-step explanation:
The statement that researchers in the Tuskegee Study had adequately covered 2 of the 3 ethics principles noted in the Belmont Report is false. The Tuskegee Study violated several fundamental ethical principles, including autonomy, beneficence, nonmaleficence, and justice. The most glaring ethical failure was the violation of autonomy, as the participants were not given informed consent about their medical condition or the true nature of the study, thereby depriving them of the opportunity to make an informed choice about their participation.
