Context and question: A major consideration was the possible Soviet reaction in the event that the US intervened. The Truman administration was fretful that a war in Korea was a diversionary assault that would escalate to a general war in Europe once the United States committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslaviaa possible Soviet target because of the Tito-Stalin Splitwas vital to the defense of Italy and Greece, and the country was first on the list of the National Security Council's post-North Korea invasion list of "chief danger spots". Truman believed if aggression went unchecked a chain reaction would be initiated that would marginalize the United Nations and encourage Communist aggression elsewhere. The UN Security Council approved the use of force to help the South Koreans and the US immediately began using what air and naval forces that were in the area to that end. The Administration still refrained from committing on the ground because some advisers believed the North Koreans could be stopped by air and naval power alone.
Why did the US not send in ground troops after the United Nations approved the use of force?
Answer: advisers believed the North Koreans could be stopped by air and naval power
Context and question: Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 C (40 F) and deliver outlet temperatures of 4560 C (113140 F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.
What are some items used to dry clothes without the use of electricity?
Answer: Clothes lines, clotheshorses, and clothes racks
Context and question: Chicago Mayor Richard M. Daley proclaimed August 10, 2005 to be "House Unity Day" in Chicago, in celebration of the "21st anniversary of house music" (actually the 21st anniversary of the founding of Trax Records, an independent Chicago-based house label). The proclamation recognized Chicago as the original home of house music and that the music's original creators "were inspired by the love of their city, with the dream that someday their music would spread a message of peace and unity throughout the world". DJs such as Frankie Knuckles, Marshall Jefferson, Paul Johnson and Mickey Oliver celebrated the proclamation at the Summer Dance Series, an event organized by Chicago's Department of Cultural Affairs.
Who proclaimed House Unity Day in Jefferson?
