Passage Summary: A water utility got the green light to charge extra to build a dam. A politician wants to take that money and use it for roads instead, but the columnist says that shouldn't be allowed.

Conclusion: The legislator's plan to divert funds from a dam project to road construction is unacceptable.

Reasoning: The revenue was specifically approved through an additional charge on water bills for the purpose of building a dam, not for building roads.

Analysis: The columnist is making a moral or procedural judgment based on the source of the funds. To justify this conclusion, we need a principle that links the 'intended use' of a fee to the 'permissibility' of its expenditure. Look for an answer that suggests it is wrong to use money collected for one specific, approved purpose on a completely different project. The argument is essentially saying that the 'bait and switch' of public funds is inherently improper.
