How about some reasons with these guesses? It's a measurable thing and its unit of measure, I can't figure this out at all. Maybe area, since it's mathematically defined by its unit as an angle is defined by its unit of measure. But that's a stretch. Last edited by Maschke; June 5th, 2018 at 01:54 PM.

Choice C introduces a square unit, so choices A and B more closely resemble the angle and degree relationship. A quart could well be used as a measure of substances other than milk, such as water, oil or beer. Also, area and volume are multidimensional. That leaves choice A.

a minute can be used as a periodic measure of time like degrees can be used as a periodic measure of angle i choose (A)
