Do they expect us peons to use diagrams to do this madness?
If a circle with a circumference of 20 has two overlapping arcs with length of 16 and 14, respectively. what is the LEAST possible total length of the overlap of the two arcs?
There are some questions like this on test day, but very annoying because it tests visual skills not math skills which I absolutely lack.

Rather than complain about ETS (which will not change) why don't you just try to solve the problem. It is VERY easy and most people can do it in their heads.
1) draw a circle and give it circumfrence 20.
2) bold out an arc of 16. Note how much "free" circle you have left. This should give you a clue as to how much overlap you MUST have if you were to draw another arc of 14.
If you draw the darn thing, you do NOT have to "visualize" it.
If you go into the test with the mindset that ETS is unfair, then you will not have a heathly mind set for solving the problems.
Just my humble opinion.
