Question: Ruth Carter Stapleton is the sister of a politican that served as President of the United States during what years?
Context: USS "Jimmy Carter" (SSN-23) is the third and last "Seawolf"-class submarine in the United States Navy.  She is named for Jimmy Carter, the 39th President of the United States; Carter is the only President who had qualified in submarines, having served as a Communications Officer, Sonar Officer, Electronics Officer, Weapons Officer, and Supply Officer while on board USS "Pomfret" .  "Jimmy Carter" is one of the few ships of the United States Navy (and only the third submarine) to have been named for a person who was alive at the time of the ship's naming, and the only submarine to be named for a living former president. The Jimmy & Rosalynn Carter Work Project - formerly the Jimmy Carter Work Project (JCWP) - is an annual home building blitz organized by Habitat for Humanity International and its affiliates.  It generally takes place in the United States one year, and an international location the next.  President Jimmy Carter and Rosalynn Carter helped Habitat volunteers renovate the 19-unit building, and media coverage brought attention to Habitat, which had been founded in 1976 in Americus, Georgia, a short distance from Carter’s hometown of Plains, Georgia.  Even though President Carter has said repeatedly he never intended to start an annual project, the following year the Carters returned to the same site to finish the renovation work.  On Oct. 10, 2013, as part of the 30th annual project, the Carters returned to the building and met with families living there.

Carter, 444 U.S. 996 (1979), was a United States Supreme Court case which was the result of a lawsuit filed by Senator Barry Goldwater and other members of the United States Congress challenging the right of President Jimmy Carter to unilaterally nullify the Sino-American Mutual Defense Treaty, which the United States had signed with the Republic of China, so that relations could instead be established with the People's Republic of China.  Goldwater and his co-filers claimed that the President required Senate approval to take such an action, under of the U.S. Constitution, and that, by not doing so, President Carter had acted beyond the powers of his office. Kenneth Jones (1952–1969), was the son of Helen Myrl Carter (of country music's Carter Family) and of Glenn Jones.  He is best remembered for a song he wrote called "Sing A Traveling Song" which appeared on Johnny Cash's albums "Hello, I'm Johnny Cash" and "Johnny Cash at Madison Square Garden".  Kenneth was Cash's nephew-in-law.  Cash's second wife, June Carter Cash, was Helen's sister.  Kenneth, or Kenny as he was also known, wrote many songs and was a talented musician.  At the time of his death he was under contract with Monument Records and appeared destined for a highly successful career.  Following his death the Carter Family recorded one of his songs, "2001 Ballad to the Future".  A few have noted the lyrics as being eerily prophetic of the September 11, 2001 terrorist attacks on the United States which took place more than thirty years after the song was written.
