Thanks for the question! The first problem with answer choice (C) is that it tells us that surviving ancient Greek and Roman texts about women doctors contain little biographical or technical data. The last lines of the passage might lead us to believe that, since we’re told that Galen, Pliny the elder, and other ancient writers give excerpts from female authority’s writing without biographical information or special comment. However, that doesn’t mean that as a whole, texts about women doctors contain little biographical or technical data. This isn’t something that’s mentioned in the passage. The second problem with (C) is that we’re told that many of these texts DON’T pointedly comment on the existence of such doctors, such as the evidence mentioned in the last paragraph starting at line 50. Finally, remember that this is a main point question, and the main point isn’t to show us generally that important inferences could be drawn from some fact. There’s a very specific point being made, which is to suggest that women doctors were part of everyday life in ancient Greece and Rome. Hope this helps! Feel free to ask any other questions that you might have.
