Example Input: Question: What was the name of Yes first two albums? 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.

Example Input: Question: What was the final score in the loss to the Houston Rockets on March 30? Passage:On December 8, 2017, the Phoenix Suns signed House to a two-way contract with the team. Throughout the rest of the season, House would split his playing time there between Phoenix and their NBA G League squad, the Northern Arizona Suns. House would make his debut with the team a day later, scoring two points and recording a single rebound in 11 minutes of play in a close loss against the San Antonio Spurs. On December 16, House would score a season-high 8 points in 15 minutes of playing time in a 108–106 win over the Minnesota Timberwolves. House was later assigned to the Northern Arizona Suns affiliate alongside Davon Reed on December 28, mainly for healing purposes. House then returned to action on January 5, 2018, recording what was at the time a new season-high 9 points in a loss against the San Antonio Spurs. On February 23, his two-way contract expired, meaning he couldn't be allowed to play for Phoenix again until after the NBA G League's first season under its rebranded name concluded. Once that happened, he was allowed to return to Phoenix for the rest of the season. On March 30, House recorded a career-high 8 rebounds in a heartbreaking, buzzer-beating loss against the Houston Rockets. On April 1, House would record a new season-high with 16 points scored alongside 6 rebounds and 3 assists in a 117–107 loss against the Golden State Warriors. Two days later, House recorded 14 points, 6 rebounds, and a career-high 5 assists in a 97–94 win against the Sacramento Kings. On April 6, House would put up his first start in the NBA against the New Orleans Pelicans. Two days later, House would record career-highs of 22 points and 8 rebounds in a 117–100 loss to the Golden State Warriors.
