Evaluate
"Should" tends to be a strong word on the LSAT. When the conclusion of an argument makes a recommendation, stating what someone "should" do, the evidence is supposed to clearly justify why that is the best course of action.
As a general rule, we accept the evidence that we're given in LR questions. However, difficult LR questions will occasionally test our critical thinking skills in a more holistic way. To answer these questions correctly, we need to be flexible and take a big-picture view, rather than mechanically following general rules.
Even though we can consider the first sentence of this argument as evidence, it stands out as rather extreme statement. Anarchy and totalitarian government control are extremes at the opposite ends of the spectrum. Most systems of government that exist fall somewhere in between. Is it reasonable to think that anarchy and totalitarian government control are the only two options available? No, it's not. There is a clear false choice flaw baked into this premise, which makes the argument questionable from the start.
