Look closely at the kinds of evidence the author has used to prove the argument.
Is the argument based on data, narrative, or both? Are narrative anecdotes the basis of the argument or do they supplement other evidence? Are there other kinds of evidence that the author should have included? Is the evidence convincing? If so, find a particularly supportive example and explain how it supports the author’s thesis. If not, give an example and explain what part of the argument is not supported by evidence. You may find that some evidence works, while some does not. Explain both sides, give examples, and let your readers know what you think overall.
