Problem: The Xbox 360 sold much better than its predecessor, and although not the best-selling console of the seventh-generation, it is regarded as a success since it strengthened Microsoft as a major force in the console market at the expense of well-established rivals. The inexpensive Nintendo Wii did sell the most console units but eventually saw a collapse of third-party software support in its later years, and it has been viewed by some as a fad since the succeeding Wii U had a poor debut in 2012. The PlayStation 3 struggled for a time due to being too expensive and initially lacking quality titles, making it far less dominant than its predecessor, the PlayStation 2, and it took until late in the PlayStation 3's lifespan for its sales and game titles to reach parity with the Xbox 360. TechRadar proclaimed that "Xbox 360 passes the baton as the king of the hill a position that puts all the more pressure on its successor, Xbox One".
Which console sold the most units in the seventh generation era?

Answer: Nintendo Wii

Problem: The birthplace of IBM, Endicott, suffered pollution for decades, however. IBM used liquid cleaning agents in circuit board assembly operation for more than two decades, and six spills and leaks were recorded, including one leak in 1979 of 4,100 gallons from an underground tank. These left behind volatile organic compounds in the town's soil and aquifer. Traces of volatile organic compounds have been identified in Endicott's drinking water, but the levels are within regulatory limits. Also, from 1980, IBM has pumped out 78,000 gallons of chemicals, including trichloroethane, freon, benzene and perchloroethene to the air and allegedly caused several cancer cases among the townspeople. IBM Endicott has been identified by the Department of Environmental Conservation as the major source of pollution, though traces of contaminants from a local dry cleaner and other polluters were also found. Remediation and testing are ongoing, however according to city officials, tests show that the water is safe to drink.
How many gallons of freon leaked into the town's soil in 1979?
