4. The following introductory paragraph is from the first draft of an essay
contrasting walking and running as techniques for reducing tension. Although
intended to be a definition paragraph, it doesn't tell us anything we don't
already know. It also relies on the tired formula of referring to a dictionary.
Rewrite the paragraph so it is more imaginative. You might use a series of an-
ecdotes or one extended example to define tension and introduce the essay's
thesis more gracefully.
