@KyleGoetz Here's what helped me with this question: The author argues that the benefit in the telecommunications industry has come because of the competition privatization allowed. Answer Choice E attacks that specific reasoning. It's saying, "Actually, author, your reasoning is faulty because you think the benefits of privatizing national parks will come because of competition - like they did when the telecommunications industry was privatized. But national parks don't work like the telecommunications industry does."

Answer Choice B is tricky because it talks about things that we know are bad. Your reasoning for choosing Answer Choice B is showing that you'd be a better political candidate than the politician in the stimulus, but Answer Choice B is not talking about the argument of the actual author, so it's wrong.

@mibuch I hope I'm seeing this correctly, but it looks like you got them right! Contrapositives are logically equal. It doesn't matter which one you come up with first.
