Passage Summary: The mayor says one specific bridge project was fine, but a report says the whole regional project it belonged to was a waste, so the mayor must be a liar.

Conclusion: The mayor was lying when he claimed the bridge renovation was not a waste of money.

Reasoning: A commission found that the larger project containing the bridge renovation was extremely wasteful.

Analysis: This argument suffers from a 'Whole-to-Part' flaw. It assumes that because a large entity (the Southern Tier Project) has a certain characteristic (being wasteful), every individual part of that entity (the bridge renovation) must share that same characteristic. When you're looking for the flaw, look for an answer that points out that a specific component can be efficient even if the larger project it is part of is a total disaster. It's a bit like saying a whole car is junk, so the brand-new tires on it must also be junk.
