The tone of the passage suggests that the author is most optimistic about the economic development potential of which of the following groups?
The best choice is C. The first two paragraphs describe shortcomings of the strategies of attracting manufacturing industries and high-technology industries, and the third paragraph describes the advantages, and mentions no disadvantages, of promoting small businesses run by local entrepreneurs. Thus, the author appears to be most optimistic about the economic development potential of local entrepreneurs. The passage’s tone does not indicate that the author is more optimistic about groups mentioned in A, B, D, and E than about local entrepreneurs.
