Passage Summary: Fewer students are quitting school lately, and the author credits a new program that aims to make students feel better about their academic success.

Conclusion: The program designed to boost student morale is the cause of the recent decrease in the high school dropout rate.

Reasoning: The dropout rate fell significantly last year, which followed the implementation of a morale-improvement program two years prior.

Analysis: To weaken this argument, we need to find an alternative explanation for why students stayed in school that has nothing to do with their morale. Perhaps the local economy took a nosedive, meaning there were no jobs for dropouts to go to, or maybe the school changed its grading scale to make passing much easier. It is a classic case of 'correlation does not equal causation,' where the author ignores other potential variables. Look for an answer that suggests the dropouts stayed put because of external pressures rather than internal happiness.
