Answer:
Answer E: undermine the traditional basis of a claim about conventional medicine’s legitimacy
Explanation:
Correct. The author discusses Eddy’s study in the context of elaborating on the question she asked in the fourth paragraph, “But how scientific is conventional ‘scientific’ medicine anyway?” This question challenges the perspective on conventional medicine described in the first paragraph, which sees conventional medicine as “scientific” and alternative medicine as “pseudoscience.” Since Eddy’s study concluded that conventional medical decision making was not based on strong scientific evidence, it provides evidence that refutes the traditional argument for the legitimacy of conventional medicine.
