In Cecropia, inspections of fishing boats that estimate the number of fish they are carrying are typically conducted upon their return to port. The high numbers so obtained have led the government to conclude that the coastal waters are being overfished. To allow commercial fishing stocks to recover, the government is considering introducing annual quotas on the number of fish that each fishing boat can catch. Compliance with the quotas would be determined by the established system of inspections.
Which of the following, if true, raises the most serious doubts about whether the government's proposed plan would succeed?

The passage starts by describing how fishing inspections work, then shows how the government interpreted the inspection results to identify a problem (overfishing), and finally presents their proposed solution (quotas) along with how they plan to enforce it (same inspection system).
The government believes that implementing annual fishing quotas, monitored through their current inspection system, will help fishing stocks recover from overfishing.
The government's plan relies on a chain of reasoning: inspection data shows high fish counts → this means overfishing → quotas will limit catches → same inspections will ensure compliance → fish stocks will recover. The logic assumes the current inspection system that identified the problem can also effectively solve it.
Weaken - We need to find information that would reduce belief in whether the government's proposed quota plan would succeed
The plan's success depends on: (1) quotas limiting actual fish catches, (2) the inspection system accurately detecting quota violations, (3) the inspection data being reliable for enforcement
Look for ways the quota system could fail despite being implemented. Focus on flaws in the inspection system, ways boats could circumvent quotas, or problems with enforcement. Since the plan relies entirely on the same inspection system that led to the overfishing conclusion, we should think about what could make this system ineffective for quota enforcement.
This tells us that some boats could catch their entire annual quota in just a few months. While this might seem problematic, it doesn't actually undermine the plan's success. Whether boats catch their quota quickly or slowly, they're still limited to that annual amount. The plan's goal is to cap total annual catches, and this choice doesn't suggest boats would exceed their quotas - just that they'd reach them faster. This doesn't raise serious doubts about the plan working.
This states that quotas would need reduction if more boats started fishing. However, this describes a potential adjustment to the plan rather than a fundamental flaw. If more boats join, quotas per boat would be lowered to maintain the same total catch limit. This is actually evidence that the plan could be adapted to maintain its effectiveness, not that it would fail.
This suggests fish prices will rise due to quotas, but that fewer boats won't enter the market. This doesn't undermine the plan's success - if the same number of boats are operating under quotas, the plan can still work as intended. Higher prices don't prevent quota enforcement or make the existing fishing boats exceed their limits.
This points out that inspectors sometimes overcount fish slightly. If anything, this would make the quota system more conservative than intended, potentially helping rather than harming fish stock recovery. A slight overcount means boats might actually be catching slightly less than the quota allows, which supports rather than undermines the plan's conservation goals.
This reveals a devastating flaw in the plan's logic. The government assumes that limiting fish brought to port (what gets counted in inspections) will reduce total fish mortality in the ecosystem. However, quotas would incentivize fishers to catch large quantities but bring only valuable fish to port, discarding the rest as dead or dying. This means actual fish removal from the ecosystem could remain just as high as before, while inspection counts show apparent compliance. Since the plan's success depends on reducing actual ecosystem impact, not just port counts, this represents the most serious challenge to whether the plan would achieve its conservation goals.
