Question: Which of Boyer's collaborators in 1977 completed their education first? Passage 1:Hebert Boyer was born in 1936 in Derry, corner of western Pennsylvania where railroads and mines were the destiny of most young men. He received his bachelor's degree in biology and chemistry from Saint Vincent College in Latrobe, Pennsylvania, in 1958. He married his wife Grace the following year. He received his PhD at the University of Pittsburgh in 1963 and participated as an activist in the civil rights movement. He spent three years in post-graduate work at Yale University in the laboratories of Professors Edward Adelberg and Bruce Carlton, then became an assistant professor at the University of California, San Francisco and a Professor of Biochemistry from 1976 to 1991, where he discovered that genes from bacteria could be combined with genes from eukaryotes. In 1977, Boyer's laboratory and collaborators Keiichi Itakura and Arthur Riggs at City of Hope National Medical Center described the first-ever synthesis and expression of a peptide-coding gene. In August 1978, he produced synthetic insulin using his new transgenic genetically modified bacteria, followed in 1979 by a growth hormone.
 Passage 2:The 2007 Major League Baseball All-Star Game was the 78th midseason exhibition between the all-stars of the American League (AL) and the National League (NL), the two leagues comprising Major League Baseball. The game was held on July 10, 2007, at AT&T Park, the home of the NL's San Francisco Giants. It marked the third time that the Giants hosted the All Star Game since moving to San Francisco for the 1958 season. The 1961 and 1984 All Star Games were played at the Giants former home Candlestick Park, and the fourth overall in the Bay Area, with the Giants bay area rivals the Oakland Athletics hosting once back in 1987, and the second straight held in an NL ballpark.
 Passage 3:Almaz was commissioned into the Baltic Fleet in 1903. At the start of the Russo-Japanese War (1904-1905), she was assigned to the Baltic Fleet, and was subsequently transferred to the Second Pacific Squadron, which transited the Suez Canal under the command of Admiral Dmitry von Fölkersam. On 28 May 1905, with most of the ships in the Russian fleet destroyed or captured at the Battle of Tsushima, Almaz was the only major ship to reach Vladivostok after the battle. She returned to the Baltic Fleet after the war, serving as an aviso and temporarily as an imperial yacht in 1908. In 1911, after repairs, she was transferred to the Black Sea Fleet and at the start of World War I was rebuilt as a seaplane tender in 1914, carrying four seaplanes. She was at the Battle of Cape Sarych on 5 November 1914.
