Problem: This set inherits a group operation (sometimes called coset multiplication, or coset addition) from the original group G: (gN) (hN) = (gh)N for all g and h in G. This definition is motivated by the idea (itself an instance of general structural considerations outlined above) that the map G G / N that associates to any element g its coset gN be a group homomorphism, or by general abstract considerations called universal properties. The coset eN = N serves as the identity in this group, and the inverse of gN in the quotient group is (gN)1 = (g1)N.e["]
What group operation is taken by the set from the original group?
The answer is the following: coset multiplication

Problem: In 1971, Tito was re-elected as President of Yugoslavia by the Federal Assembly for the sixth time. In his speech before the Federal Assembly he introduced 20 sweeping constitutional amendments that would provide an updated framework on which the country would be based. The amendments provided for a collective presidency, a 22-member body consisting of elected representatives from six republics and two autonomous provinces. The body would have a single chairman of the presidency and chairmanship would rotate among six republics. When the Federal Assembly fails to agree on legislation, the collective presidency would have the power to rule by decree. Amendments also provided for stronger cabinet with considerable power to initiate and pursue legislature independently from the Communist Party. Dzemal Bijedic was chosen as the Premier. The new amendments aimed to decentralize the country by granting greater autonomy to republics and provinces. The federal government would retain authority only over foreign affairs, defense, internal security, monetary affairs, free trade within Yugoslavia, and development loans to poorer regions. Control of education, healthcare, and housing would be exercised entirely by the governments of the republics and the autonomous provinces.
How many sweeping constitutional amendments did Tito introduce in 1971?
The answer is the following: 20

Problem: Because it was designated as the national capital, many structures were built around that time. Even today, some of them still remain which are open to tourists.

Problem: The current economy of the city is basically newly developed based on the past. Service industries are dominating, accounting for about 60 percent of the GDP of the city, and financial industry, culture industry and tourism industry are top 3 of them. Industries of information technology, energy saving and environmental protection, new energy, smart power grid and intelligent equipment manufacturing have become pillar industries. Big private firms include Suning, Yurun, Sanpower, Fuzhong, Hiteker, 5stars, Jinpu, Tiandi, CTTQ Pharmaceutical and Simcere Pharmaceutical. Big state-owned firms include Panda Electronics, Yangzi Petrochemical, Jinling Petrochemical, Nanjing Chemical, Nanjing Steel, Jincheng Motors, Jinling Pharmaceutical, Chenguang and NARI. The city has also attracted foreign investment, multinational firms such as Siemens, Ericsson, Volkswagen, Iveco, A.O. Smith, and Sharp have established their lines, and a number of multinationals such as Ford, IBM, Lucent, Samsung and SAP established research center there. Many China-based leading firms such as Huawei, ZTE and Lenovo have key R & D institutes in the city. Nanjing is an industrial technology research and development hub, hosting many R & D centers and institutions, especially in areas of electronics technology, information technology, computer software, biotechnology and pharmaceutical technology and new material technology.
Companies such as Ford, IBM, Lucent, Samsung and SAP have built what in Nanjing?
The answer is the following:
research center
