Politician: Every regulation currently being proposed by the Committee for Overseas Trade will reduce the trade deficit. Our country' s trade deficit is so large that it weakens the economy. Ttherefore, each of the proposed regulations would help the economy. The reasoning in the politician's argument is flawed in that the argument
A: takes for granted that the trade deficit will increase in size if no action is taken to reduce it
B: merely appeals to the authority of the committee without evaluating any reasons for the proposed regulations
C: concludes that every regulation in a set will have the same effects as a set of regulations as a whole
D: fails to consider the possibility that one effect of a regulation will be offset by other effects
