Which of the following best describes the relation of the first paragraph to the passage as a whole?
The best answer is A. In the first paragraph, the author presents a general observation about contemporary business; the rest of the passage narrates a specific series of recent events concerning two companies in particular. The story of these companies serves as an example that illustrates the observation being made in the first paragraph of the passage.
Choices B and C can be eliminated because the author does not advance an argument.
Although the passage does advance an argument, the author does not anticipate that the conclusions being drawn will be disputed, so choice D is also incorrect.
