Final answer:
Theodore Roosevelt held many positions such as New York state legislator, Police Commissioner, Vice President, and Governor of New York, but he was never Chief Justice of the U.S. Supreme Court.
Step-by-step explanation:
T.R.'s professional background included all of the following jobs: a New York state legislator, New York City Police Commissioner, Vice-President of the U.S., and Governor of New York. The one job T.R., or Theodore Roosevelt, did not hold was e. Chief Justice of the U.S. Supreme Court. Roosevelt's storied career included several roles that undoubtedly shaped his eventual presidency, such as assistant secretary of the navy, leader of the Rough Riders during the Spanish-American War, and President of the United States after the assassination of President William McKinley. However, his career path never included becoming Chief Justice of the U.S. Supreme Court, a position that requires legal expertise and typically many years of judicial experience.
