Input: Read this: Renewable energy commercialization involves the deployment of three generations of renewable energy technologies dating back more than 100 years. First-generation technologies, which are already mature and economically competitive, include biomass, hydroelectricity, geothermal power and heat. Second-generation technologies are market-ready and are being deployed at the present time; they include solar heating, photovoltaics, wind power, solar thermal power stations, and modern forms of bioenergy. Third-generation technologies require continued R&D efforts in order to make large contributions on a global scale and include advanced biomass gasification, hot-dry-rock geothermal power, and ocean energy. As of 2012, renewable energy accounts for about half of new nameplate electrical capacity installed and costs are continuing to fall.
Question: As of 2012, what accounts for about half of new nameplate electrical capacity?

Output: renewable energy


Input: Read this: The idea of Masonic brotherhood probably descends from a 16th-century legal definition of a brother as one who has taken an oath of mutual support to another. Accordingly, Masons swear at each degree to keep the contents of that degree secret, and to support and protect their brethren unless they have broken the law. In most Lodges the oath or obligation is taken on a Volume of Sacred Law, whichever book of divine revelation is appropriate to the religious beliefs of the individual brother (usually the Bible in the Anglo-American tradition). In Progressive continental Freemasonry, books other than scripture are permissible, a cause of rupture between Grand Lodges.
Question: In what branch can books, other than scripture, be used for the purpose of oath taking?

Output: Progressive continental Freemasonry


Input: Read this: The American people are mostly multi-ethnic descendants of various culturally distinct immigrant groups, many of which have now developed nations. Some consider themselves multiracial, while acknowledging race as a social construct. Creolization, assimilation and integration have been continuing processes. The African-American Civil Rights Movement (1955–1968) and other social movements since the mid-twentieth century worked to achieve social justice and equal enforcement of civil rights under the constitution for all ethnicities. In the 2000s, less than 5% of the population identified as multiracial. In many instances, mixed racial ancestry is so far back in an individual's family history (for instance, before the Civil War or earlier), that it does not affect more recent ethnic and cultural identification.
Question: What are the English people mostly descendants of?

Output: unanswerable


Input: Read this: On December 30, 1922, with the creation of the Soviet Union, Russia became one of six republics within the federation of the Union of Soviet Socialist Republics. The final Soviet name for the republic, the Russian Soviet Federative Socialist Republic, was adopted in the Soviet Constitution of 1936. By that time, Soviet Russia had gained roughly the same borders of the old Tsardom of Russia before the Great Northern War of 1700.
Question: In which war was Russia involved in 1710?

Output:
unanswerable
