Thanks for the question! So this is a main point question. (E) says that the main point is that physicians have been encouraged to think of themselves as technicians and need to reorient themselves toward ethical concerns. Remember, main point questions need to both actually be the main point, and be true. Is it even true in the first place that it’s the physicians themselves who have been encouraged to think of themselves as technicians? No, it’s other people who think of them as technicians, not the physicians themselves. Thus, (E) isn’t even something the passage states, and can’t be the main point.
Hope this helps! Feel free to ask any other questions that you might have.
