So I’m clicking through some certification documents and processes. One of them is a long preliminary explanation followed by a multiple choice exam. The topic is on Bend Radius for electrical wiring installations.

The first question was effectively: what is the definition of a bend radius?

A. The minimum angle…

B. The maximum angle…

C. The sharpest angle…

D. None of the above.

So, I click “D. None of the above.” Why? Because a radius (a distance from a point) isn’t an angle, duh.

But it’s marked wrong.

**sigh**

Edit: and then there’s the misuse and misapplication of commas.
