V10-31

Official Solution:


Dietitian: I advise my clients not to follow the 2012 government recommendations for a healthy diet. In the 1980s, the government advocated eating a high proportion of carbohydrates, and [b]the current nationwide epidemic of obesity began about the same time. When the government updated its recommendations in 2012, it admitted its guidelines from the 1980s were mistaken. Thus, you can’t believe the new guidelines have any validity because they could be just as flawed as the earlier guidelines.

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

A. The first is evidence used to support the dietician’s main conclusion; the second is that conclusion
