Passage Summary: The superintendent noticed that interns drop out at a much lower rate than other students, so he concludes that the internship program itself is what keeps them in school.

Conclusion: Participating in a work internship causes a student to be less likely to drop out of high school.

Reasoning: The dropout rate for students in internships is only 1 percent, compared to 11 percent for the general student population.

Analysis: The superintendent is confusing correlation with causation. While it's true that interns drop out less often, we don't know if the internship *caused* that behavior. It’s highly likely that students who are motivated enough to seek out and complete an internship are already the types of students who were unlikely to drop out in the first place. Look for an answer that identifies this 'self-selection' bias or the possibility that a third factor explains both the internship and the graduation.
