 United States of America: The torch relay's North American leg occurred in San Francisco, California on April 9. On the day of the relay officials diverted the torch run to an unannounced route. The start was at McCovey Cove, where Norman Bellingham of the U.S. Olympic Committee gave the torch to the first torchbearer, Chinese 1992 Olympic champion swimmer Lin Li. The planned closing ceremony at Justin Herman Plaza was cancelled and instead, a ceremony was held at San Francisco International Airport, where the torch was to leave for Buenos Aires. The route changes allowed the run to avoid large numbers of China supporters and protesters against China. As people found out there would be no closing ceremony at Justin Herman Plaza, there were angry reactions. One demonstrator was quoted as saying that the route changes were an effort to "thwart any organized protest that had been planned." San Francisco Board of Supervisors President Aaron Peskin, a critic of Mayor Gavin Newsom, said that it was a "cynical plan to please the Bush State Department and the Chinese government because of the incredible influence of money." Newsom, on the other hand, said he felt it was in "everyone's best interest" and that he believed people had been "afforded the right to protest and support the torch" despite the route changes. Peter Ueberroth, head of the U.S. Olympic Committee, praised the route changes, saying, "The city of San Francisco, from a global perspective, will be applauded." People who saw the torch were surprised and cheered as shown from live video of CBS and NBC. The cost to the city for hosting the event was reported to be USD $726,400, nearly half of which has been recovered by private fundraising. Mayor Gavin Newsom said that "exponential" costs associated with mass arrests were avoided by his decision to change the route in consultation with police chief Heather Fong.
The route end was changed from Justin Herman plaza to what?
A: San Francisco International Airport

Socialism confronted consumerism in the chain State Department Stores (GUM), set up by Lenin in 1921 as a model retail enterprise. It operated stores throughout Russia and targeted consumers across class, gender, and ethnic lines. GUM was designed to advance the Bolsheviks' goals of eliminating private enterprise and rebuilding consumerism along socialist lines, as well as democratizing consumption for workers and peasants nationwide. GUM became a major propaganda purveyor, with advertising and promotional campaigns that taught Russians the goals of the regime and attempted to inculcate new attitudes and behavior. In trying to create a socialist consumer culture from scratch, GUM recast the functions and meanings of buying and selling, turning them into politically charged acts that could either contribute to or delay the march toward utopian communism. By the late 1920s, however, GUM's gandiose goals had proven unrealistic and largely alienated consumers, who instead learned a culture of complaint and entitlement. GUM's main function became one of distributing whatever the factories sent them, regardless of consumer demand or quality.
What group was established in 1912 in response to the clash between socialism and consumerism? 
A: unanswerable

One of the problems of the standard electric light bulb is filament notching due to evaporation of the filament. Small variations in resistivity along the filament cause "hot spots" to form at points of higher resistivity; a variation of diameter of only 1% will cause a 25% reduction in service life. These hot spots evaporate faster than the rest of the filament, which increases the resistance at that point—this creates a positive feedback that ends in the familiar tiny gap in an otherwise healthy-looking filament. Irving Langmuir found that an inert gas, instead of vacuum, would retard evaporation. General service incandescent light bulbs over about 25 watts in rating are now filled with a mixture of mostly argon and some nitrogen, or sometimes krypton. Lamps operated on direct current develop random stairstep irregularities on the filament surface which may cut lifespan in half compared to AC operation; different alloys of tungsten and rhenium can be used to counteract the effect.
Which gases are not typically used in a light bulb?
A: unanswerable

The Appalachians are also home to two species of fir, the boreal balsam fir (Abies balsamea), and the southern high elevation endemic, Fraser fir (Abies fraseri). Fraser fir is confined to the highest parts of the southern Appalachian Mountains, where along with red spruce it forms a fragile ecosystem known as the Southern Appalachian spruce-fir forest. Fraser fir rarely occurs below 5,500 ft (1,700 m), and becomes the dominant tree type at 6,200 ft (1,900 m). By contrast, balsam fir is found from near sea level to the tree line in the northern Appalachians, but ranges only as far south as Virginia and West Virginia in the central Appalachians, where it is usually confined above 3,900 ft (1,200 m) asl, except in cold valleys. Curiously, it is associated with oaks in Virginia. The balsam fir of Virginia and West Virginia is thought by some to be a natural hybrid between the more northern variety and Fraser fir. While red spruce is common in both upland and bog habitats, balsam fir, as well as black spruce and tamarack, are more characteristic of the latter. However balsam fir also does well in soils with a pH as high as 6.
What is the lowest asl oaks are usually found at?
