Passage Summary: A government report says a city has a bad dropout problem because many adults living there didn't finish high school. A school official thinks this is wrong based on actual school data.

Conclusion: The survey report concludes that Center City has one of the highest school dropout rates in the nation.

Reasoning: The survey calculated the proportion of current residents over age 19 who did not graduate from high school.

Analysis: The core problem here is a mismatch between the group being measured and the conclusion being drawn. The survey looks at everyone currently living in the city, but it doesn't account for where those people actually went to school. If many non-graduates moved into Center City after leaving school elsewhere, the city's own school system isn't actually responsible for those 'dropouts.' You should look for an answer that points out the survey's failure to distinguish between current residents and people who actually attended the local schools. It's a bit like blaming a hospital for the health of people who were already sick when they moved into the neighborhood.
