Thanks for the question! So we’re trying to figure out the question the author poses in lines 7-10 and what it introduces. What is that question? It’s asking why physicians should resist efforts to give the practice of medicine a new meaning. Is this expressing a general fascination with the origins of words in general? No, it’s much more specific; it relates to medicine. So a choice as broad as (E) can’t be correct.
Hope this helps! Feel free to ask any other questions that you might have.
