Passage Summary: An activist argues that because nuclear energy is risky and we have new ways to make power from waste and nature, we can finally stop using nuclear plants entirely.

Conclusion: There is a realistic possibility that we can completely replace nuclear power with alternative energy sources while better protecting the environment.

Reasoning: Nuclear power is dangerous and fossil fuels are finite, but new technology can create fuel from sewage sludge, and other renewables like solar and wind are available.

Analysis: This question asks for the consideration that is LEAST relevant to the activist's argument. To evaluate the practicability of this hope, we need to know if these alternative sources can actually meet total energy demand, if they are cost-effective, and if they truly are better for the environment than nuclear power. An irrelevant consideration would be something that doesn't impact the feasibility or the environmental benefit of the proposed switch. Look for an answer choice that focuses on a detail unrelated to the scale, cost, or impact of the transition.
