Question Type:
Necessary Assumption
Stimulus Breakdown:
The public square used to be an important tool of democracy because it provided a forum for citizens to discuss important issues. Today, the internet plays the role of the public square.
Therefore, keep the 'net (at least as) free (as the public square)!
Answer Anticipation:
There are two gaps I can see here:
1) The conclusion brings up the new idea of "at least as much freedom". It might be possible to still serve the important function without the same level of freedom.
2) The Internet can serve the same role as the public square, but it might not be the only thing that can. Maybe the Internet can be regulated because there's another forum that already serves this function.
Correct answer:
(C)
Answer choice analysis:
(A) Degree. The argument never talks about having "complete" freedom. Additionally, it wouldn't make much sense for the conclusion to state that at least as much as complete freedom of expression is needed.
(B) Degree. The argument doesn't require all citizens to have the same level of freedom. It's possible the Internet could serve this role with citizens all having a baseline level of freedom, but with some having more freedom than others.
(C) This answer choice relates freedom to effectiveness, which is within the scope of the argument. Negating a conditional is difficult, but it involves negating the arrow - the negation here is: Participants lacking the ability to discuss issues freely doesn't necessarily impact the effectiveness of a tool. If this is true, then freedom doesn't have to be assured in order for this tool to work, and the argument falls apart. This answer probably wouldn't be a first-round pick, but since it's in-scope, I'd negate it and see it's the correct answer.
(D) Unnecessary comparison. As long as it's used to discuss important issues, it doesn't matter to the argument if that's only a minority of the discussion. So keep those cat pictures coming.
(E) Tempting! This is related to the second noted gap. However, it is too strong to be necessary. The argument doesn't require that the Internet is the only tool for democracy. There could be others that are much, much less effective and so the Internet should be left free.
Takeaway/Pattern:
In a Necessary Assumption question, leave and negate any answer that's at least within scope and doesn't have a degree issue.
