Alright.  And ordered some books too.  

Robert Harbin - author page on Amazon

Robert J. Lang - author page on Amazon

Such - RL is the NASA engineer in one of the previous videos and not only has he developed relevant folding designs for space craft materiel, he left NASA in the early 2000s to see if he could make a living doing origami. Wonderful entrepreneurial streak there. 

And here from my art supply box - origami paper from Kyoto circa 1997.

Probably all of us know how to make cranes and small inflatable boxes, but there is so much more...!

It made sense to me. In each of the columns the middle square represents the union of both the upper and lower squares of that column less the common elements they share. For the unknown square, look at the first square in that column and look for any of its elements that do not appear in the middle square. These will be the common elements of both the first square and the unknown third square. Second, look for any elements in the middle square that do not appear in the first square. These will be the unique elements of the third square. Add the first and second sets together and you get the square represented by option e.
