Critic: The Gazette-Standard newspaper recently increased its editorial staff to avoid factual errors.
Conclusion
The move to increase editorial staff to avoid factual errors is clearly not working (i.e. there are at least as many factual errors since the increase in editorial staff was enacted).

Usually, when we're weakening an Anti-Causal argument, we're saying that the Comparison evidence presented is not a fair comparison (they had different initial reference points / they have different realities that make it unfair to compare along these lines).
Goal
We can prephrase any Weaken question by thinking, .
So,
But in particular we might look for an answer that makes the Evidence less compelling; some way in which this paper and its biggest competitor are unfair to compare.
