Which statement about grading is TRUE?

  • A.It always precedes cleaning in a line
  • B.It removes damaged material
  • C.It sorts sound produce into classes
  • D.It is another word for cleaning

Answer: C

Correct answer: It sorts sound produce into classes

Grading and cleaning answer different questions. Cleaning removes what should not be in the lot at all; grading takes what remains and sorts it into classes by size, weight, colour or quality for sale. Grading therefore follows cleaning, and there is no point grading material that still contains trash.
