Hey Anna Catherine, I think overall you've done a nice job editing this section of the article. I know you've already cut down a lot on the wordiness of the original article but it still feels a little lengthy to me. I know it's a lot of information to try to convey but maybe try to make it a little more concise. Personally, I would like to see each of the extrinsic factors only be a couple of sentences long and just cite the studies for people who want examples. Other than that, the only thing is that a couple of the sections (permanent pathological conditions, age, and the second extrinsic factor) are lacking citations, I'm not sure if you were responsible for finding these or not though. you can't find a citation for them, I would think about taking them out. Overall though, I think you've done a lot of work and definitely have improved the article a lot!
