Passage Summary: The government spends a ton on cleaning up toxic spills but isn't actually finishing the job, and more spills are happening every year. The author suggests we should spend more on stopping spills before they happen, especially since the prevention budget is currently tiny compared to cleanup costs.

Conclusion: The government should shift a larger portion of its funding toward the prevention of chemical spills.

Reasoning: Current cleanup efforts are failing to finish even a single site while new spills outpace them, and prevention is fundamentally more effective and currently underfunded.

Analysis: The specific proposal mentioned in the stem serves as the main conclusion of the argument. I identified this by noting that the preceding sentences provide the context of a problem (ineffective cleanup), while the subsequent sentence provides the justification (prevention is more effective) for the proposal. In LSAT terms, the proposal is the 'point' of the passage—the recommendation that the evidence is intended to support. There is a clear 'premise-conclusion' relationship where the final sentence explains *why* we should adopt the proposal.
