Question: How many years did Pietro Pellegri attend the Genoa youth academy? Passage 1:Sothoron broke into the major leagues when the spitball was still legal. His best season came in 1919, when he posted a 20–13 record with a 2.20 earned run average for the Browns, finishing fifth in the American League in wins and ERA. After the spitball was outlawed following the 1919 campaign, Sothoron at first was not permitted to throw it, then in mid-1920 he was added to a list of 17 spitballers in the majors who were allowed to continue using the banned pitch. But he was never able to match his 1919 numbers. His pitching career ended in St. Louis with the National League Cardinals, where he played for his first MLB manager, Branch Rickey, and led the NL in shutouts with four in , despite a mediocre 10–16 (3.57) record. During his MLB career, he appeared in 264 games pitched, and allowed 1,583 hits and 596 bases on balls in 1,582⅓ innings pitched. He struck out 576 and hurled 102 complete games.
 Passage 2:His musical education started in 1977 on the piano, at Nysa School of Music. Then, in 1981, he started to play on trumpet while continuing to perfect the piano skills, in Chrzanów School of Music. In 1989, after graduating from the Secondary School of Music in Kraków, majoring in trumpet (minor in piano), he first entered John Paul II University to play organ and later (in 1990) matriculated to Musical University in Kraków to study music theory. Finally, in 1992 he began study in Katowice at the prestigious Karol Szymanowski University of Music’s School of Jazz and Popular Music. In 1995, he received his master's degree with Honors as a Jazz Vocalist. In January 2012, he received PhD degree from the Fryderyk Chopin University of Music in Warsaw. In June 2014, he completed the process of habilitation at the Fryderyk Chopin University of Music in Warsaw, gaining the rank of a "habilitated doctor,"- equivalent to the American title of "assistant-professor." The title of his work was "Polska piosenka popularna interpretowana w języku jazzowym. Analiza utworów z płyty ŚPIEWNIK." ("Polish pop music translated into the language of jazz. An analysis of the works from "Śpiewnik.")
 Passage 3:Born in Genoa, Pellegri is a youth product of the Genoa youth academy. On 22 December 2016, he made his debut with the senior team in Serie A in a 1–0 away loss against Torino, coming on as an 88th-minute substitute for Tomás Rincón. At the age of 15 years and 280 days, he equalled the record as the youngest ever Serie A debutant, held by Roma's Amedeo Amadei since 1937. In doing so he also became the first player born in the 21st century to appear in Serie A, and the second player born in the 2000s to make his Italian top-flight debut after Moise Kean. On 28 May, he scored his first Serie A goal in a 3–2 away loss against Roma, becoming the first player born in the 21st century to ever score in Serie A, and the third youngest goalscorer ever in the Italian top flight, after Amadei and Gianni Rivera.

It was published by Ballantine Books from 1972 to 1980, Pocket Books from 1981 to 1983, Baen Books in 1984, and Tor Books from 1985 to 1987. The Tor Books volumes bore the title Terry Carr's Best Science Fiction of the Year from 1985 to 1986, and Terry Carr's Best Science Fiction and Fantasy of the Year in 1987. Most volumes were also issued in hardcover in the United Kingdom by Gollancz, the last three under the variant title Best SF of the Year. The series was a continuation of the earlier anthology series World's Best Science Fiction, edited by Carr with Donald A. Wollheim, published from 1965 to 1971 by Ace Books.

 Passage 2:In 1839, Lin Zexu, who himself was a Fuzhou native, was appointed by the Daoguang Emperor to enforce the imperial ban on the opium trade in Canton. His unsuccessful actions, however, precipitated the disastrous First Opium War with Great Britain, and Lin, who had become a scapegoat for China's failure in war, was exiled to the northwestern section of the empire. The Treaty of Nanjing (1842), which put an end to the conflict, made Fuzhou (then known to Westerners as Foochow) one of five Chinese treaty ports, and it became completely open to Western merchants and missionaries. was one of the most important Protestant mission fields in China. On January 2, 1846, the first Protestant missionary, Rev. Stephen Johnson (missionary) from ABCFM (美國公理會差會), entered the city and soon set up the first missionary station there. ABCFM was followed by the Methodist Episcopal Missionary Society that was led by Revs. M. C. White and J. D. Collins, who reached Fuzhou in early September 1847. The Church Missionary Society also arrived in the city in May 1850. These three Protestant agencies remained in Fuzhou until the communist revolution in China in the 1950s, leaving a rich heritage in Fuzhou's Protestant culture. They supported the creation of hospitals and schools, including the Woolston Memorial Hospital, run by the American-trained Hü King Eng.
 Passage 3:Herpesviruses are a third group of common cancer-causing viruses. Two types of herpesviruses have been associated with cancer: the Epstein–Barr virus (EBV) and human herpesvirus 8 (HHV-8). EBV appears to cause all nonkeratinizing nasopharyngeal carcinomas and some cases of lymphoma, including Burkitt's lymphoma—the association is especially strong in Africa—and Hodgkin's disease. EBV has also been found in a variety of other types of cancer cells, although its role in causing these other cancers is not well established. KSHV/HHV-8 causes all cases of Kaposi's sarcoma, and has been found in some cases of a cancer-related condition called Castleman's disease. Studies involving other kinds of cancer, particularly prostate cancer, have been inconsistent. Both of these herpesviruses are commonly found in cancerous cells of primary effusion lymphoma. Herpesviruses also cause cancer in animals, especially leukemias and lymphomas.
