Question

which is the strongest claim for a presentation about the global problem of a lack of clean drinking water?
the united states is one of the many countries that are very lucky to have access to well water, bottled water, and tap water
everyone deserves access to clean drinking water, but it is unlikely that this goal can ever be reached
the lack of access to clean drinking water poses a serious health risk around the world, and funds must be raised to help achieve universal access.
it is interesting to note that 82% of people who lack access to improved water live in rural areas, while just 18% live in urban areas.

Explanation:

A strong presentation claim about the global clean water crisis should state a clear problem, its impact, and a call to action. The first option focuses only on the U.S., which is narrow. The second option is defeatist and offers no actionable direction. The fourth option is just a statistical observation without a core argument. The third option identifies the health risk (a critical impact) and proposes a concrete step (raising funds) to address the issue, making it the strongest, most purpose-driven claim.

Answer:

The lack of access to clean drinking water poses a serious health risk around the world, and funds must be raised to help achieve universal access.
