Difficulty: MediumPrinciple Questions

A municipal water authority recently decided to replace lead service lines on private residential properties at public expense, even though property owners are contractually responsible for maintenance between the property line and the home. The authority's board reasoned that while private owners bear legal responsibility for their own pipes, the failure of individual homeowners to replace aging lead lines poses a severe health hazard to neighboring residents who share connected distribution segments and cannot protect themselves from cross-contamination.

Which one of the following principles, if valid, most helps to justify the water authority's decision?

  1. A
    Public authorities are obligated to assume full financial responsibility for any infrastructural repairs that individual homeowners are unable or unwilling to complete on their own.
  2. B
    Public entities should mandate private funding for residential improvements whenever those improvements eliminate potential hazards to the general community.
  3. A public agency is justified in using collective resources to remediate conditions on private property when private inaction creates serious physical hazards for third parties who are powerless to prevent those hazards.Answer
  4. D
    Any municipal utility repair that involves connecting infrastructure must always be funded entirely by public revenue regardless of private ownership agreements.
  5. E
    A municipal agency may intervene in private property maintenance only when the preexisting contractual division of responsibility has been formally nullified by a court.

Answer

A public agency is justified in using collective resources to remediate conditions on private property when private inaction creates serious physical hazards for third parties who are powerless to prevent those hazards.
The correct answer provides a general principle that directly validates the board's action: when private inaction creates unavoidable hazards for innocent third parties, a public agency is justified in using public funds to intervene and rectify the issue.

Step-by-Step Solution

1
Identify the conclusion and the supporting premises in the argument.
The water authority concluded that it should publicly fund lead line replacements on private properties because private inaction exposes neighboring residents to unavoidable cross-contamination risks.
Principle-Justify questions require identifying the exact gap between the factual circumstances and the institutional action taken.
2
Isolate the logical gap between the factual premises and the normative conclusion.
The premises describe an externality where private property neglect harms third parties; the conclusion asserts that the public authority is justified in spending public funds to remedy the private issue.
The correct principle must state that when private inaction harms vulnerable third parties, public intervention and funding are justified.
3
Evaluate the answer choices to identify the rule that provides a sufficient bridge without overextending scope or reversing conditions.
The principle stating that public agencies may use collective resources to remedy private property conditions when inaction harms third parties precisely justifies the board's decision.
This rule connects the specific factual premises directly to the normative conclusion.
