Passage Summary: It makes sense that fewer people are getting hurt at work because fewer people are working, but it's weird that the rate of injury is also dropping.

Reasoning: Total injuries falling makes sense if there are fewer workers, but the rate of injury per worker falling requires a different explanation.

Analysis: We need to explain why the likelihood of an individual worker getting hurt has decreased. Four answers will provide a reason for this (e.g., safer conditions, less dangerous jobs being cut first), and the 'EXCEPT' answer will either be irrelevant or make the lower rate even more confusing. Look for an answer that doesn't explain why the workplace became safer on average for the remaining employees.
