PT119 · S4 · Q13 James: Many people claim that

This would potentially be a good answer if it assured us that Reade's opponents are also discussing complex issues. But this only says that they're discussing "some" of the same issue (some = at least one), and so we don't know if any of those mutually-discussed issues are one of the complex ones.

One of our goals was to argue "Reade isn't popular because she discusses complex issues". Can we say, "After all, her critics accuse her of oversimplifying those complex issues"? Not really. If the opponents are accusing Reade of oversimplifying, then we can tell that Reade is doing at least some simplifying of these complex issues. But if you're simplifying complex issues as you're discussing them, that would potentially be appealing to voters. So this answer might actually help the plausibility that Reade's discussion of complex issues is a big part of her popularity.

A decline in popularity doesn't tell us why the popularity existed in the first place. This doesn't help us assess whether popularity came more from discussing complex issues or appearing competent / trustworthy.

The word Some (or any other word that only represents at least one data point) is almost never correct on Strengthen, Weaken, Paradox, and Sufficient Assumption. This does support the plausibility of Maria's hypothesis, but it only provides one data point, whereas the correct answer addresses most voters, which is a much bigger data set.
