Mayor McKinney' s policies have often been criticized on the grounds that they benefit only wealthy city residents, but that is not a fair evaluation. Some of McKinney' s policies have clearly benefited the city' s less affluent residents. McKinney actively supported last year' s proposal to lower the city' s high property taxes. Because of this tax decrease, more development is taking place in the city, helping to end the housing shortage and stabilize the rents in the city. Which one of the following most accurately expresses the main conclusion of the argument? ['The decrease in property taxes that McKinney supported caused more development to take place in the city.', "The criticism that McKinney's policies benefit only the wealthy is unjustified.", "McKinney's efforts helped end the housing shortage and stabilize the rents in the city.", "McKinney's policies have often been criticized for benefiting only wealthy city residents."]
