City study: After the city adopted a city-wide recycling mandate, usage of the local landfill fell by 15 percent. The mayor concludes that the mandate succeeded in changing residents' behavior.
Which one of the following, if true, identifies the most significant logical flaw in the mayor's argument?
- The argument infers that the mandate produced the decline merely from the decline's having followed the mandate
- The argument treats a condition needed to cut landfill use as if it were enough to bring that result about
- The argument fails to show that a 15 percent decline is large enough to justify keeping the policy
- The argument generalizes about all residents from an unrepresentative sample of them
- The argument never establishes precisely how much of the decline was due to commercial rather than household waste
