I also found this very confusing, the only way I can make it clearer in my mind is to stop thinking about one circle inside of the other and instead think that "ALL" is Sufficient for "MOST" as a necessary, and "MOST" is Sufficient for "SOME" as a Necessary. By this logic they are subsets to supersets. Am I wrong in thinking this way?

So dumb mistake on my part, but I couldn't get it for a good 5 minutes because I kept thinking that when they said "Most Produce" they were talking about the almonds grown in California (referential), not produce as in vegetables of fruits. Sometimes these lessons are unnecessarily confusing.

One word got me, "One"- I picked D because I though it said "There is no way..." It really says, "There is no one way" which makes the answer wrong. These small mistakes kill me.
