Question: How many terms as a senator did  Robert Kean's father serve? Passage:Kean was born September 28, 1893, in Elberon, New Jersey. His father, Hamilton Fish Kean (1862–1941), was a United States Senator from New Jersey and his son, Thomas Kean, served two terms as the Governor of New Jersey. Robert Kean was the great-great-grandson of John Kean, a Delegate to the Continental Congress from South Carolina (1756–1795). His uncle, John Kean (1852–1914), was also a United States Senator from New Jersey. His grandson, Thomas Kean, Jr., is presently the Minority Leader of the New Jersey State Senate. His mother, Katherine Taylor Winthrop (1866–1943), was a descendant of John Winthrop, a wealthy English Puritan lawyer and one of the leading figures in the founding of the Massachusetts Bay Colony, the first major settlement in what is now New England after Plymouth Colony. Winthrop led the first large wave of migrants from England in 1630 and served as governor for 12 of the colony's first 20 years of existence.

Question: Which of the four expansion teams had the best record in their first year? Passage:In 1969, the Padres joined the ranks of Major League Baseball as one of four new expansion teams, along with the Montreal Expos (now the Washington Nationals), the Kansas City Royals, and the Seattle Pilots (now the Milwaukee Brewers). Their original owner was C. Arnholt Smith, a prominent San Diego businessman and former owner of the PCL Padres whose interests included banking, tuna fishing, hotels, real estate and an airline. Despite initial excitement, the guidance of longtime baseball executives, Eddie Leishman and Buzzie Bavasi as well as a new playing field, the team struggled; the Padres finished in last place in each of its first six seasons in the NL West, losing 100 games or more four times. One of the few bright spots on the team during the early years was first baseman and slugger Nate Colbert, an expansion draftee from the Houston Astros and still the Padres' career leader in home runs.

Question: When were the ships that the Victory ships were designed to replace first built? Passage:Named after Whittier College in Whittier, California, the ship was built at the California Shipbuilding Yard (Calship) in Los Angeles, California in just 82 days and was delivered on 18 July 1945. The Whittier City and Whittier College was named for author John Greenleaf Whittier. SS Whittier Victory was the 798 of the 10,500-ton class known as Victory ships, built under the Emergency Shipbuilding program. Victory ships were designed to replace the earlier Liberty ships. Liberty ships were designed to be used solely for World War II. Victory ships were designed to last longer and serve the US Navy after the war. The Victory ship differed from a Liberty ship in that it was faster, longer, wider, taller, and had a thinner stack set farther toward the superstructure and a long raised forecastle. She was a United States Merchant Marine ship operated by the Moore-McCormack Lines for World war 2. She loaded up cargo at a few west coast ports and streamed to support the Pacific War. SS Whittier Victory delivered supplies in the island-hopping campaigns towards the Empire of Japan. As a Merchant Marine ship, she had a civilian crew to man the ship and US Navy Armed Guards to man the deck guns.
