Practice Revising for
Support and Detail
Support is the evidence, examples, or facts that show, explain, or prove 
your main point. Primary support points are the major ideas developed 
in the paragraphs that make up the body of your essay. Supporting de-
tails are the specifi cs that explain your primary support to your readers.
  When you read your draft essay, ask yourself: Do you provide enough 
information for your reader to understand the main point? Do you present 
enough evidence to convince your reader of that point? Look for places 
where you could add more support and detail.
  Read the two paragraphs that follow, and note the support the writer 
added to the second one. Notice that she didn’t simply add to the paragraph; 
she also deleted some words and rearranged others to make the story clearer 
to readers. The additions are underlined; the deletions are crossed out.

911, the police will be there.
