Read the passage carefully and answer the question that follows.

Water shortages are increasingly shaping public health, livelihoods, and social stability across many regions. Although the planet contains abundant water, safe and affordable supplies are unevenly distributed. In many lower-income communities, families face dry taps or polluted sources while wealthier neighbourhoods and powerful users receive more reliable access. This imbalance is not merely the result of weather patterns; it is reinforced by decisions about investment, ownership, and political influence.

Efforts to address the problem often move slowly because influential agricultural, industrial, and energy groups oppose changes that could limit their access. Methods such as collecting rainwater and converting seawater can help in particular places, but they cannot by themselves ensure fair distribution. Lasting water security requires accountable public institutions, open decision-making, and policies that regard water as a shared necessity rather than a product reserved for those with greater power or wealth.

Which change in policy perspective does the passage most strongly support?

Correct Answer: Viewing water as a common essential service instead of a product controlled by purchasing power

Step-by-Step Explanation:

1. Understand the Core Question:
The question asks to identify the policy perspective change that is most strongly supported by the provided text.

2. Analyze the Key Arguments in the Passage:
• The first paragraph explains that water shortages and unequal distribution are not just natural occurrences, but are reinforced by social, financial, and political factors.
• The second paragraph discusses limitations of technical fixes (such as rainwater collection and seawater conversion) and explicitly outlines what is necessary for long-term water security.

3. Identify the Explicit Conclusion:
The author explicitly states in the final sentence:
"Lasting water security requires accountable public institutions, open decision-making, and policies that regard water as a shared necessity rather than a product reserved for those with greater power or wealth."

4. Evaluate the Options:
• Viewing water as a common essential service instead of a product controlled by purchasing power: Directly matches the text's emphasis on treating water as a "shared necessity" rather than a commercial product for the wealthy.
• Handing worldwide water allocation entirely to private companies: Contradicts the passage, which advocates for accountable public institutions and fair public access.
• Giving industrial expansion priority over environmental and social concerns: Contradicts the passage, which notes that powerful industrial interests currently hinder equitable water distribution.
• Relying solely on seawater conversion technologies to solve unequal access: Contradicts the passage, which states that such technologies "cannot by themselves ensure fair distribution."

Conclusion:
The passage clearly supports shifting policy towards treating water as a shared essential service for all rather than a commodity driven by market purchasing power.
