An environmental scientist argues that a proposed dam construction project will severely harm the local ecosystem by altering river flow and destroying critical habitats. A government official counters that the dam is necessary for economic development, providing electricity and irrigation, and that its environmental impact will be minimal and manageable. Which of the following, if true, would most effectively weaken the government official's counter-argument?
- AThe dam project is expected to create hundreds of temporary construction jobs.
- BThe proposed irrigation system would primarily benefit large commercial farms, not small local farmers.
- CLocal communities have expressed strong support for the economic benefits the dam could bring.
- DNew studies suggest that the projected electricity demand for the region has been significantly overestimated.
Show answer & explanationAnswer & explanation
Correct answer: D. New studies suggest that the projected electricity demand for the region has been significantly overestimated.
The government official's counter-argument relies on the dam being 'necessary' for economic development, specifically by providing electricity and irrigation. If a key benefit (electricity) is not as needed as claimed, it undermines the 'necessity' of the dam and thus weakens the official's counter-argument that the economic benefits outweigh environmental concerns.
Why the other options are wrong
- A. Temporary jobs are an economic benefit, supporting the official's claim, not weakening it.
- B. While this highlights an equity issue, it doesn't challenge the *existence* of the irrigation benefit or its overall contribution to economic development, just who benefits.
- C. Community support for economic benefits reinforces the official's argument, not weakens it.
Weakening a Counter-Argument
To weaken a counter-argument means to identify information that makes the opposing viewpoint less convincing or less valid, often by challenging its premises, assumptions, or the relevance of its claims.
- Targets an opposing argument.
- Reduces the credibility of the counter-argument.
- Can be achieved by disproving a premise or assumption.
Memory trick: Defend your point, attack the counter's might.
