The question allows, and even encourages, one of two short,
simple, direct answers.  (Hint:  the longer one has three
letters.)

Rather than opt for one of the obvious simple answers, you
chose instead to give a long-winded and indirect reference to
some of your earlier gobbledygook.  I think even you aren't
sure what you're saying, but certainly others are not.

For your next writing, try to remember:  use short, simple,
direct sentences.

Your grade on this assignment:  F.
