Weight loss programs that guarantee results mislead their customers. No program can ensure that someone who follows it will lose weight. These programs prey upon unhappy and insecure people who are often driven more by emotion than by reason. Moreover, many people who lose weight while on a program eventually regain the weight within a year. So while the programs' claims may be true for a short period, customers will be disappointed in the long run.

The two portions in boldface play which of the following roles?

A:The first is a generalization; the second is a consequence of that generalization.

B:The first is the author's position; the second is a consideration in support of that position.

C:The first is an opinion under examination; the second is evidence weighing against that opinion.

D:The first is an assertion that the author questions; the second is evidence in support of that assertion.

E:The first is evidence in support of the author's main point; the second is the author's main point.

正确答案： B:The first is the author's position; the second is a consideration in support of that position.

The conclusion of this argument is the first sentence: “Weight loss programs that guarantee results mislead their customers.” The rest of the text is evidence in support of that conclusion. The correct answer will identify the first boldface portion as the conclusion, and the second boldface portion as evidence in support of the conclusion.

(A) The first boldface portion is a fairly strong assertion, not a generalization. The second boldface portion is not a consequence of the first.

(B) CORRECT. The first boldface portion is the author's position, or conclusion. The second boldface portion is a consideration in support of the position stated in the first boldface portion.

(C) The second boldface portion is evidence in support of the opinion stated in the first boldface portion, not weighing against it.

(D) The first boldface portion is the author’s assertion, not one that he or she questions.

(E) The first boldface portion is the author’s main point, not evidence in support of it. The second boldface portion is not the author's main point, but rather support for it. This answer choice incorrectly reverses the roles of the boldface portions.
