PROBLEM: Question: Does the Syrian government have control over the town where US launched airstrikes that killed dozens pro-Syrian government militiamen? Passage: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.

PROBLEM: Question: Who did Steve Howe replace someone else as Yes's guitarist? Passage:Hot on the heels of the huge success of CSNY and Led Zeppelin, British band Yes rapidly established themselves as one of the leading groups in the burgeoning progressive rock genre, and their success also played a significant part in establishing the primacy of the long-playing album as the major sales format for rock music in the 1970s. After several lineup changes during 1969–70, the band settled into its "classic" incarnation, with guitarist Steve Howe and keyboard player Rick Wakeman, who both joined during 1971. Although the extended length of much of their material made it somewhat difficult to promote the band with single releases, their live prowess gained them an avid following and their albums were hugely successful – their third LP The Yes Album (1971), which featured the debut of new guitarist Steve Howe, became their first big hit, reaching #4 in the UK and just scraping onto the chart in the US at #40. From this point, and notwithstanding the impact of the punk/new wave movement in the late 1970s, the band enjoyed an extraordinary run of success—beginning with their fourth album Fragile, each of the eleven albums they released between 1971 and 1991 (including the lavishly packaged live triple-album Yessongs) made the Top 20 in the US and the UK, and the double-LP Tales of Topographic Oceans (1973) and Going For The One (1977) both reached #1 in the UK.
