WeakenDiff: Hard

Logic Breakdown

Passage Summary: An editorialist argues against raising speed limits, claiming that even if speeders stop breaking the law, the rule-followers will just drive faster, making the roads more dangerous.

Conclusion: Raising speed limits to match actual driving speeds would significantly decrease highway safety.

Reasoning: While current speeders might obey the new higher limits, those who currently follow the law would likely speed up, increasing the overall average speed.

Analysis: The editorialist assumes that a higher average speed is the primary driver of danger. To weaken this, we should look for an answer that suggests safety is influenced by something other than just average speed—perhaps the *variance* in speed between cars is what causes accidents. If raising the limit makes everyone drive at a more uniform speed, it might actually be safer, even if that uniform speed is higher. It's a classic case of a speaker ignoring a potentially more important variable.

Which one of the following, if true, most seriously weakens the editorialist's argument?

Correct Answer
B
If uniformity of speeds matters more for safety than a low average speed, then raising limits—likely narrowing the spread between fast and slow vehicles—could improve or at least not harm safety even if the average speed rises. This directly undercuts the editorialist’s safety conclusion.
