Passage Summary: A manager claims a nuclear plant is safer than most other jobs because the current rate of worker injuries is much lower than the national average.

Conclusion: The nuclear power plant is safer than the majority of other industrial workplaces.

Reasoning: The plant's current rate of injury for its workers is 3.2 per 200,000 hours, which is less than half the national average for all industrial plants.

Analysis: To weaken this argument, we need to find a flaw in using 'current injury rates' as the sole definition of 'safety.' The manager is comparing routine industrial injuries (like slips or falls) to a nuclear environment, which might have low daily injury rates but high risks of long-term illness or rare but catastrophic disasters. Look for an answer that suggests the manager's data is incomplete or that it ignores more significant types of danger. A workplace isn't necessarily 'safer' just because people aren't tripping over rugs if there's a hidden risk of radiation exposure.
