A is a trap. We need a strengthener that focuses on the generic drug...saying that the brand-name drugs cost no more than generic drugs gives us reason to believe that all else being equal, perhaps we might choose the brand-name drugs. However, we already know that the generic costs less and is equally effect.
Generic drugs contain exactly the same active ingredients as their brand-name counterparts, but usually cost much less to develop, produce, and market. So, generic drugs are just as effective as their brand-name counterparts, but cost considerably less.
Which of of the following, if true, most strengthens the argument?
A) The ingredients used in the manufacture of brand-name drugs cost no more than the ingredients used to produce their generic counterparts. X
B) Generic drugs are no more likely than brand-name drugs to suffer from defects in composition. CORRECT
C) Generic drugs are just as likely as brand-name drugs to be readily available in pharmacies. X
D) The higher costs of brand-name drugs underwrite drugs companies' heavy investment in research. X
E) Because of advertising, doctors frequently prescribe brand-name drugs by their brand name, rather than by their chemical name. X
