Passage Summary: A commissioner says that because the city is short a billion dollars and can't raise more money, they have to cut spending; since they have one plan that saves a billion, they claim it's the only possible solution.

Conclusion: The only way to solve the budget shortfall is to adopt this specific plan.

Reasoning: There is a billion-dollar deficit that can only be fixed by cutting spending, and the current plan provides exactly a billion dollars in feasible cuts.

Analysis: The commissioner is suffering from a serious case of tunnel vision. Just because this specific plan *would* work to save a billion dollars doesn't mean it's the *only* plan that could do so. There are likely countless ways to mix and match different budget cuts to reach that same billion-dollar goal. The flaw lies in treating a sufficient condition (a plan that works) as a necessary one (the only plan that works). Look for an answer that points out the failure to consider alternative sets of cuts.
