Question: Which band that The Neighborhoods' toured with has the most records sold overall? Passage:The Neighborhoods are a Boston rock band formed in 1978. The band earned local fame by playing regularly at Boston venues such as The Rat and winning the WBCN Rock 'n' Roll Rumble in 1979 (beating out La Peste, Mission of Burma, among others). Their 1980 debut single, "Prettiest Girl" (b/w "No Place Like Home") was a local hit. The band broke up for a short time between 1980-1981, but reformed in 1982 with bassist Lee Harrington and went on to release 5 albums between 1984-1991. In 1987 they opened for David Bowie on his Glass Spider tour at Sullivan Stadium in Foxborough, MA and later toured with the Ramones in '87, Cheap Trick in '90 and Tin Machine in '91. In 1992 they decided to disband and played what was supposed to be their farewell show at The Rat. A recording of that show was released in 2010 as a double live CD with Brad Whitford of Aerosmith guesting on 2 songs. Whitford produced the band's 1990 and 1991 albums. The band reformed in 2003 with Minehan, Harrington and Johnny "Rock" Lynch (Avoid One Thing) and continues to play shows today. In 2005, the band was inducted into the Boston Music Awards Hall of Fame and in 2006, their song "Parasite" was featured on the Guitar Hero 2 game and soundtrack. The band is currently working on a new studio album at David Minehan's Woolly Mammoth Sound Studios in Waltham, MA.

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.
