According to MacRae's textbook chapter, what is the length of a typical paragraph in nonacademic, professional writing? NOTE that he says "lines," not "sentences" $($because lines in some documents are shorter, depending on margins!$)$; mentioning this because you'll follow his $($and my$)$ rules for paragraphs in this class.

$4-8$ lines

$2-6$ lines

$6-8$ lines

MacRae doesn't cite a standard.
