Passage Summary: A council member argues that because the other side hasn't proven their idea is better, his own idea must be the winner by default.

Conclusion: The shoe factory is a superior choice for the emergency shelter compared to the courthouse.

Reasoning: Opponents of the shoe factory site have failed to provide evidence supporting their claim that the courthouse is a better alternative.

Analysis: This argument commits a classic 'appeal to ignorance' fallacy. The speaker assumes that because a competing claim (the courthouse) lacks evidence, the original proposal (the shoe factory) must be correct. In the world of logic, failing to prove 'B' is better than 'A' does not automatically prove that 'A' is actually good. Look for an answer choice that identifies this error of treating a lack of proof against a position as positive proof for that position.
