Problem: Background: Exodus is an American thrash metal band formed in 1979 in Richmond, California. The band has gone through numerous lineup changes, two extended hiatuses, and the deaths of two former band members. Their current lineup consists of guitarists Gary Holt and Lee Altus, bassist Jack Gibson, drummer Tom Hunting, and lead vocalist Steve "Zetro" Souza. Hunting is one of the original members, and departed from Exodus twice, in 1989 and 2004, but rejoined in 2007.
Context: The initial lineup of Exodus was formed in the late 1970s by guitarists Kirk Hammett and Tim Agnello, drummer/vocalist Tom Hunting, and vocalist Keith Stewart while attending high school together. The band added bass guitarist Carlton Melson in 1980, and the quintet began making a name for themselves playing backyard parties and various school functions. They played mostly cover songs in the vein of 1970s hard rock and New wave of British heavy metal (NWOBHM) acts but also developed some of their own original songs. Things with Stewart did not work out, and Hunting became the band's sole vocalist for some time. Carlton Melson was replaced in 1981 by bass guitarist Geoff Andrews. Tim Agnello would leave the group soon after to pursue a life of ministry in Stockton, California, leaving Exodus to perform as a power trio until a replacement was found in Hammett's friend and Exodus roadie Gary Holt.  Also in 1981, Hammett met El Cerrito resident Paul Baloff at a North Berkeley house party, a friendship that was started - according to Hammett - by their shared admiration for punk rock and 1970s heavy metal music. Baloff became the band's lead vocalist and the quintet recorded a 3-track demo tape in 1982 consisting of the songs "Whipping Queen", "Death and Domination" and "Warlord", a release which would be Hammett's only recording with Exodus. The band's music began to incorporate elements of hardcore punk into their NWOBHM roots, and Exodus were considered the pioneers of the Bay Area thrash metal scene. In November 1982, Exodus opened a show at San Francisco's Old Waldorf venue for Metallica, a then-relatively unknown (and unsigned) band from Los Angeles. As the band began playing more shows in Bay Area clubs, they gained a large, fervent fan base known for their violent concert behavior.  In early 1983, Hammett left Exodus to join Metallica on the recommendation of Mark Whitaker, leaving Gary Holt to effectively take creative control of the band. Hammett was replaced short term by Mike Maung, followed by Evan McCaskey, before the band finally found a permanent replacement in guitarist Rick Hunolt. Geoff Andrews also left to start an early incarnation of pioneering death metal band Possessed, and was replaced by bass guitarist Rob McKillop.  In the spring of 1984, Exodus entered Turk Street Studios with producer Doug Piercy to record demos of songs that would later appear on their debut album. The band was signed to New York-based Torrid Records and Exodus prepared to enter Prairie Sun Recording Studios that summer.
Question: where was the band located?
Answer: 

Problem: Background: Samuel de Champlain (also known as "The Father of New France) (French: [samYel d@ Saple] born Samuel Champlain; on or before August 13, 1574 - December 25, 1635), "The Father of New France", was a French navigator, cartographer, draftsman, soldier, explorer, geographer, ethnologist, diplomat, and chronicler. He made from 21-29 trips across the Atlantic, and founded New France and Quebec City on July 3, 1608. He is important to Canadian history because he made the first accurate map of the coast and he helped found the settlements.
Context: During the summer of 1609, Champlain attempted to form better relations with the local native tribes. He made alliances with the Wendat (called Huron by the French) and with the Algonquin, the Montagnais and the Etchemin, who lived in the area of the St. Lawrence River. These tribes demanded that Champlain help them in their war against the Iroquois, who lived farther south. Champlain set off with nine French soldiers and 300 natives to explore the Riviere des Iroquois (now known as the Richelieu River), and became the first European to map Lake Champlain. Having had no encounters with the Iroquois at this point many of the men headed back, leaving Champlain with only 2 Frenchmen and 60 natives.  On July 29, somewhere in the area near Ticonderoga and Crown Point, New York (historians are not sure which of these two places, but Fort Ticonderoga historians claim that it occurred near its site), Champlain and his party encountered a group of Iroquois. In a battle begun the next day, two hundred Iroquois advanced on Champlain's position, and one of his guides pointed out the three Iroquois chiefs. In his account of the battle, Champlain recounts firing his arquebus and killing two of them with a single shot, after which one of his men killed the third. The Iroquois turned and fled. This action set the tone for poor French-Iroquois relations for the rest of the century.  The Battle of Sorel occurred on June 19, 1610, with Samuel de Champlain supported by the Kingdom of France and his allies, the Wyandot people, Algonquin people and Innu people against the Mohawk people in New France at present-day Sorel-Tracy, Quebec. The forces of Champlain armed with the arquebus engaged and killed or captured nearly all of the Mohawks. The battle ended major hostilities with the Mohawks for twenty years.
Question: What did these tribes want from Champlain?
Answer:
These tribes demanded that Champlain help them in their war against the Iroquois, who lived farther south.
