For this topic sentence, what is the best, most logical order for the following
supporting sentences?
Topic sentence: My friend Susan McCarthy, coauthor of When Elephants
Weep, recently reminded me that reading about eating can occasionally send
one running away from the kitchen.
1: "They sort of peel them with their teeth," she explained.
II: Susan has considered posting this passage on her refrigerator as an
appetite suppressant.
III: She mentioned a passage she had read about how killer whales feed on
humpback whales.
—Anne Fadiman, "The Literary Glutton" Ex Libris: Confessions of a
Common Reader (New York: Farrar, Straus, and Giroux, 1998).

#2 comes first because it starts with the name Susan. The other options include a 'she.' The readers wouldn't know who she is without saying her name first.

#3 comes next because it explains #1. If #1 came before #3, the readers would be confused about who is grinding what, and the sentence would make no sense.

In summary, to put these in order, pay attention to what the readers know and don't know, so you don't confuse them by bringing up something they no nothing about without explaining it first.

Hope this helped!
