The body paragraphs in an outline for an argumentative essay should be arranged by least important to most important facts.
arranged by shortest to longest sections.
divided by a system of letters and numbers.
divided by a system of upper- and lowercase letters.

this questions kinda confusing but I believe the best answer would be divided by a system of upper- and lowercase letters.

It makes sense cause a sentence has uppercase and lower case letters so an essay would be divided into upper and lower case letters

hope that helps...
