　　 The claim that . . . figures in the economist’s argument in which one of the following ways

　　 In the argument given, the two portions in boldface play which of the following roles

　　 The first boldface statement has what relationship to the second boldface statement

　　Before you look at the answers:

　　1. Pinpoint the main conclusion in the passage.

　　2. Separate the premises from everything else. After finding the main conclusion, don’t assume that all the other statements are premises; they might include opposing viewpoints, background information, or concession.

　　3. Analyze the structure of the argument. In other words, figure out how the various pieces of an argument or a passage fit together logically.

　　4. Then, in your own words, describe what role the statement mentioned in the prompt plays. Is it the main conclusion, an intermediate conclusion, a premise, an opposing viewpoint, a view that author is trying to support, a concession Avoid looking at the answers until you have forced yourself to describe the statement’s role.

　　Then look for the answer that most accurately describes what you just described:

　　1. Focus on the active clause of each answer to help yourself move through the answers faster.

　　2. The correct answer must describe exactly what is happening in the passage. Make sure every word of that answer correlates with some part of the passage. In other words, translate the abstract terms into concrete terms from the passage. If the statement is the argument’s main conclusion, for example, but the argument also has an intermediate conclusion, then the answer that the statement “is the author’s only conclusion” would be wrong; it is not the only conclusion, even though it is the main conclusion.
