Section 2, #22, of the June 2007 LSAT presents us with a loose, but reasonable, causal chain of events: First, the media does a shitty job of covering politics. Simultaneously, politicians conduct their business in secret. The result of these two things is that citizen action is less likely to influence politics. And the result of THAT, in turn, is that citizens lose interest in politics.
I think that’s basically what’s happening here. There are TWO initial causal factors (bad media and government secrecy), and one end result: people give up on politics.
The question asks us “Which one of the following is most strongly supported by the editorialist’s statements.” I am not, by nature, a conservative. But I’m going to pretend I’m conservative when I’m answering this question.
