Question: How many league championships have been won by the team that signed Thomas as an undrafted free agent? Passage 1:Thomas went undrafted after his junior career but signed as a Free Agent with the Toronto Maple Leafs. He began his NHL career in the 1984–85 season. Thomas was born in Stockport, England but was raised in Markham, Ontario, Canada where he attended Markham District High School. As he often coasted in school on his hockey skills, he once had a teacher tell him to "smarten up, Steve; hockey can only take you so far". He played junior hockey for the Toronto Marlboros of the OHL (he was the last original Toronto Marlboro to make it to the Maple Leafs of the NHL). Prior to playing in the NHL, Thomas won the Dudley "Red" Garrett Memorial Award in 1985 as the top rookie in the American Hockey League, while playing for the St. Catharines Saints.
 Passage 2:Pederson was born in Palo Alto, California, and is the son of Shelly (Cahn) and Stu Pederson. Stu played in eight games for the Los Angeles Dodgers in 1985, and spent a total of 12 years in Minor League Baseball. Joc's mother was an athletic trainer in college. Pederson grew up a San Francisco Giants fan. He is Jewish by birth, and is eligible because he is Jewish to play for the Israel national baseball team, which he has played on. Through 2019, Pederson was second among Jewish baseball players in career home run frequency (behind Hank Greenberg), 7th in career slugging percentage (behind Kevin Youkilis), and 10th in career home runs (behind Mike Epstein). Pederson's Jewish maternal great-great-great-grandfather and great-great-great-uncle immigrated to the United States in the 1840s, and were charter members of synagogue Temple Emanuel in San Francisco. His great-great-grandfather Leopold Cahn (born in 1864; son of Israel Cahn, a wool merchant), great-grandmother Zelda Sugarman (born in 1907), and great-great-grandmother Fannie Morris (born in 1873) were born in San Francisco. In terms of his religious identity, Pederson has described himself as "pretty much nothing."
 Passage 3:Tensions between the Syrian Army and the Syrian Democratic Forces in the eastern bank of the Euphrates of Deir ez-Zor Governorate have always been high following the liberation of Deir ez-Zor city from ISIL and the SDF's capture of large parts of the area following its offensive against ISIL with CJTF–OIR support. On 16 September 2017, either Syrian or Russian aircraft bombed SDF positions on the eastern bank. On 25 September, Russian and Syrian forces shelled SDF forces in the nearby Conoco gas field. Between 7 February and 8 February 2018, clashes between the SDF and pro-Syrian government forces near Khasham resulted in US airstrikes on pro-government forces which killed dozens of pro-government militiamen, allegedly including contractors of the Russian private military company Wagner Group. Additional armed incidents took place in the following weeks.
