i was somewhat confused by this one. is it flawed because the argument falsely assumes that because one corporation, Byworks Corporation, is nonprofit and inefficient, all other nonprofits cannot be efficient?

The argument concludes that philanthropists do not want to make nonprofit sector as efficient as private business in this country. Why would they want this when one example, Byworks Corporation, is so inefficient that it loses money year after year. The issue in this reasoning is that Byworks Corporation is just one example of private business and may not be representative of private business in general. Answer choice (B) points out this error of reasoning.

Incorrect Answers
(A) is not true. The evidence includes the question, "why would they want to?" This forms part of the evidence and so the conclusion about what ought to be the case is not entirely about what is the case.
(C) is not true. There is no criticism of the editor in refuting the editor's position.
(D) is not true. There is evidence used to support the conclusion--it just so happens to be potentially unrepresentative.
(E) incorrectly discusses the cause of a phenomenon. No such causal argument is presented.
