the highlighted portion mentions that
many people are blaming fast food for the rise in obesity. The rest of the argument is structured to highlight OTHER REASONS why obesity has been on the rise. So, the industry representative structures his argument to counter this general idea (that fast food is the sole cause of the rise in obesity)
So, let's analyze the answer choices:
A. It is the conclusion the argument seeks
to prove. - the argument does not seek to prove the bold faced statement; in fact, it is structured to do the exact opposite. Hence,
eliminate (A).
B. It is a finding that an opposing argument cannot explain.- the boldfaced statement is NOT a finding but a belief (or a popular statement) that the argument tries to counter. Hence,
eliminate (B)C. It is a line of reasoning that the
argument concludes is correct. - the argument DOES NOT agree with the bold faced statement. Hence,
eliminate (C).D. It is a piece of evidence supporting the argument's main conclusion. - the boldfaced statement is not a piece of evidence but a popular belief. Hence,
eliminate (D)E. It describes a statement that the argument seeks to counter. - BINGO. this is exactly what the representative tries to do. Hence,
(E) is the right answer.
