It is really a bad question.
I guess the real answer they are looking for would depend on what the options they give you on the test.
So far we have found 36" (pools), Between 3' and 4' (dishwashers) and 18" (disposals & range hoods).
I picked on 680.22 because that is the only article that specifically says "motors" and lists a length.
Appliances may have motors in them but that is not the way the article is worded.
