Final answer:
Jimmy Carter reformed the civil service of the United States federal government as a response to the Watergate scandal.
Step-by-step explanation:
The individual who reformed the civil service of the United States federal government, partly in response to the Watergate scandal, was Jimmy Carter. Following the resignation of President Richard Nixon due to his involvement in the Watergate scandal, Gerald Ford became president but was unable to address the problems faced by the nation. Jimmy Carter, who succeeded Ford as the thirty-ninth president, took steps to reform the civil service and move beyond the Watergate scandal.
