Passage Summary: To fix environmental issues that aren't the government's fault, people need to change how they act, but they only change when it saves or makes them money; therefore, solutions need to be profitable.

Conclusion: Most serious ecological problems will likely only be solved if the solutions are made financially attractive to consumers.

Reasoning: Environmental problems not caused by government mismanagement require changes in consumer habits, and consumers will only change their habits if there is an economic incentive to do so.

Analysis: The argument sets up a conditional chain: if a problem is not from government mismanagement, it requires consumer change, which in turn requires economic enticement. However, the conclusion jumps to 'serious ecological problems' in general. The 'Gap' here is the assumption that these serious ecological problems actually fall into the category of 'not resulting from government mismanagement.' To guarantee the conclusion, we need an assumption that links 'serious ecological problems' to the conditions described in the premises. Look for an answer that ensures these problems aren't just government-managed issues in disguise.
