Q: Passage: The 19th annual Arab League summit reaffirmed the Arab Peace Initiative first adopted in 2002 (also known as the Beirut Declaration). Arab leaders at the summit urged Israel to accept this initiative. Saudi Foreign Minister Prince Saud al-Faisal said that the plan would have a strong chance of winning international support and of reviving Israeli–Arab peace talks if adopted unanimously by all Arab leaders. The plan, moreover, set up a mechanism to promote the peace plan that would pave the way for Arab countries with no ties to Israel, including Saudi Arabia, to open channels of communications with the Jewish state—a longtime goal for various presidential administrations in the United States. The peace initiative, as Middle Eastern scholars explain, was considered a "great leap from historical resolutions of 1964 and 1967, which had vowed to destroy Israel." Under the plan, Arab nations would recognize Israel if Israel withdrew from land it occupied in the 1967 Arab-Israeli war. Moreover, the plan allows for the creation of a Palestinian state—with its capital in East Jerusalem—and the return of Palestinian refugees based on United Nations General Assembly Resolution 194. The final draft of the plan, moreover, avoided mentioning the phrase "right of return", which has been a point of contention in all previous peace talks; instead it called for a "just solution to the Palestinian refugee problem."

Q: Passage: The Pittsburgh Pirates are traced back to the Pittsburgh Yellow Jackets of the US Amateur Hockey Association. The Yellow Jackets' owner was Roy Schooley, a former referee. Even though the team won the USAHA Championship in 1924 and 1925, Schooley encountered financial problems. His team was then sold to attorney James F. Callahan. Pittsburgh was granted a franchise by the National Hockey League on November 7, 1925. The move came after Eddie Livingstone, the former owner of the Toronto Shamrocks and the Toronto Blueshirts of the National Hockey Association saw Pittsburgh as a possible member for a proposed rival league to the NHL; Pittsburgh had, in the 1890s, been the first metropolitan area to professionalize the game of ice hockey. In order to thwart the new league, the President of the NHL, Frank Calder, negotiated to put a franchise in Pittsburgh, which become the seventh team to join the NHL as well as the league's third US-based team. Callahan then renamed his team the Pittsburgh Pirates, after he received permission from Barney Dreyfuss, the owner of the Pittsburgh Pirates baseball team.
