The results of a recent poll in the United States indicate that the public, by 80 percent to 17 percent, opposes relaxation of existing regulation of air pollution. Furthermore, not a single major segment of the public wants environmental laws made less strict. The results of this poll reveal that legislators, by voting for renewal of the Clean Air Act, will be responsive to the will of the public without alienating any significant special-interest groups.
Which of the following pieces of information would be most useful in evaluating the logic of the argument presented above
A．The groups in the population that were defined as major segments of the public and the groups defined as specialinterest groups.
B．The length of time that current federal environmental laws have been in effect and the length of time that states have regulated air pollution.
C．The probable economic effect of renewal of the Clean Air Act on those opposed to and those in favor of relaxing environmental laws.
D．The people whom the author hopes to influence by citing the results of the poll.
E．(E) The percentage of those surveyed who chose not to respond to the questions asked of them.
