[EX Q]: Question: How many years did Nick Van Exel play for the Nuggets? Passage:The 1998–99 NBA season was the Nuggets' 23rd season in the National Basketball Association, and 32nd season as a franchise. During the offseason, the Nuggets acquired Nick Van Exel from the Los Angeles Lakers, and second-year guard Chauncey Billups from the Toronto Raptors. Despite the return of Antonio McDyess, who was re-signed by the team after one season with the Phoenix Suns, the Nuggets continued to struggle under new head coach Mike D'Antoni losing eight of their first nine games. Top draft pick Raef LaFrentz out of Kansas was out for the remainder of the season with a knee injury after playing just twelve games. The Nuggets finished the lockout shortened season sixth in the Midwest Division with a 14–36 record. This was also their final season playing at McNichols Sports Arena. Following the season, second-year forward Danny Fortson and Eric Williams were both traded to the Boston Celtics, and D'Antoni was fired as coach.

[EX Q]: Question: Which place is older, Chernihiv or Lutsk? Passage:In 1180, Ingvar Yaroslavich joined Ryurik Rostislavich in his struggle against Sviatoslav Vsevolodovich of Chernihiv. According to the Tale of Igor's Campaign, Ingvar was a brave man, however, he never wanted to irritate his powerful neighbors. In 1183, for instance, Ingvar refused to accommodate Vladimir II Yaroslavich in Dorogobuzh, who had been banished from Halych. It appears that Ingvar was wary of Yaroslav Osmomysl, Vladimir Yaroslavich's father. Soon after this, Ingvar took the place of his older brother Vsevolod Yaroslavich as the ruler of Lutsk. In 1202, Ingvar was appointed ruler of Kiev instead of the ousted Ryurik Rostislavich in accordance with a deal between Roman Mstislavich of Halych and Vsevolod the Big Nest, Grand Prince of Vladimir. Ryurik, however, would regain Kiev that same year with the help of the Olgovichs and polovtsy. In 1204, Ingvar took part in capturing the city of Volodymyr-Volyns'kyi together with Alexander of Belz. He was appointed ruler of the city on the spot, but was soon replaced by Alexander due to boyars' discontent. In 1208–1211, Ingvar sent his son to assist Daniil Romanovich in his struggle against the sons of Igor Sviatoslavich of Novhorod-Siverskyi. In 1212, Ingvar and Mstislav Romanovich attacked Vsevolod Sviatoslavich and captured Kiev. After a battle near Belgorod Ingvar voluntarily ceded Kiev to Mstislav Romanovich and left for Lutsk.
