Okay, I am happy to help you understand if I can.  Basically, whenever there's a statement like (for example) ""...is widely-considered a delicacy"" or ""...was regarded as his greatest failure/success"" or anything like that, it's a good idea to show an inline citation to make it clear that the point of view being discussed is verifiable and is not just the editor's own POV or own conclusion.  I'm not sure where this is explained in the MOS or similar documents, but after a time you'll probably come to instantly recognize where these are needed.  Happy editing. -   "
