text_A: In his first year as mayor, Medill received very little legislative resistance from the Chicago City Council. He vetoed a relatively modest eleven City Council ordinances that year, and even most of those were narrowly involved with specific financial practices he considered wasteful, and none of the vetoes were overridden. He used his new powers to appoint the members of the newly constituted Chicago Board of Education and the commissioners of its constituted public library. His appointments were approved unanimously by the City Council.
text_B: Could one get the impression that Chicago's city council was generally reluctant to change, and had allowed a lot of waste and inefficiency to build up that would have remained if Medill was not elected mayor?
NO.
