Snarky Mathematics Venn Diagram: Version 1.01

This is my Version 1.01.

I'm sure that it can be improved.

(I was, of course, inspired partly by this Venn diagram.)

Update: One of my friends caught a grammatical error, so I fixed it for Version 1.01. That is the only difference between Versions 1.0 and 1.01.

Update (3/12/19): Franklin Kenter pointed out correctly to me that a four-set Venn diagram requires three dimensions, so let's say that what I drew is a "Venn-like" diagram, given that I am missing some of the intersections. (My positioning of the different sets was one that gave me the intersections that I wanted.)
