Columnist: Wildlife activists have proposed that the practice of stringing cable TV lines from the same poles that carry electric power lines should be banned because cable TV lines, while electrically neutral themselves, make it easier for animals to climb near electric power lines, risking electrocution. This particular argument for banning the practice fails, however, since some animals are electrocuted by power lines even where cable TV lines are all underground. Which one of the following most accurately describes a flaw in the columnist's reasoning? ['It rejects an argument for a proposal merely on the grounds that the proposal would not completely eliminate the problem it is intended to address.', 'It rejects a proposal to address a problem merely on the grounds that other proposals to address the problem would also be effective.', 'It fails to consider the additional advantageous effects that a proposal to address a problem might have.', "It takes a sufficient condition for an argument's being inadequate to be a necessary condition for its being inadequate."]
