Problem: Renewable energy commercialization:

Worldwide use of solar power and wind power continued to grow significantly in 2012. Solar electricity consumption increased by 58 percent, to 93 terawatt-hours (TWh). Use of wind power in 2012 increased by 18.1 percent, to 521.3 TWh. Global solar and wind energy installed capacities continued to expand even though new investments in these technologies declined during 2012. Worldwide investment in solar power in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind power investment was down 10.1 percent, to $80.3 billion. But due to lower production costs for both technologies, total installed capacities grew sharply. This investment decline, but growth in installed capacity, may again occur in 2013. Analysts expect the market to triple by 2030. In 2015, investment in renewables exceeded fossils.

Use of wind power in 2012 decreased by what percentage?

A: unanswerable

Problem: George VI's reign saw the acceleration of the dissolution of the British Empire. The Statute of Westminster 1931 had already acknowledged the evolution of the Dominions into separate sovereign states. The process of transformation from an empire to a voluntary association of independent states, known as the Commonwealth, gathered pace after the Second World War. During the ministry of Clement Attlee, British India became the two independent dominions of India and Pakistan in 1947. George relinquished the title of Emperor of India, and became King of India and King of Pakistan instead. In 1950 he ceased to be King of India when it became a republic within the Commonwealth of Nations, but he remained King of Pakistan until his death and India recognised his new title of Head of the Commonwealth. Other countries left the Commonwealth, such as Burma in January 1948, Palestine (divided between Israel and the Arab states) in May 1948 and the Republic of Ireland in 1949.
In what year did Clement Attlee become the minister?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Historically, the channel's programming consisted mainly of featured classic theatrically released feature films from the Turner Entertainment film library which comprises films from Warner Bros. Pictures (covering films released before 1950) and Metro-Goldwyn-Mayer (covering films released before May 1986). However, TCM now has licensing deals with other Hollywood film studios as well as its Time Warner sister company, Warner Bros. (which now controls the Turner Entertainment library and its own later films), and occasionally shows more recent films. Turner Classic Movies is a dedicated film channel and is available in United States, United Kingdom, France (TCM Cinema), Spain (TCM Espana), Nordic countries, Middle East and Africa.
Up until what month and year of release are films from Metro-Goldwyn-Mayer part of the Turner Entertainment library?
A: May 1986

Context and question: Since the middle of the 19th century, Masonic historians have sought the origins of the movement in a series of similar documents known as the Old Charges, dating from the Regius Poem in about 1425 to the beginning of the 18th century. Alluding to the membership of a lodge of operative masons, they relate a mythologised history of the craft, the duties of its grades, and the manner in which oaths of fidelity are to be taken on joining. The fifteenth century also sees the first evidence of ceremonial regalia.
The Old Charges are dated from when to when?
Answer: about 1425 to the beginning of the 18th century

Question: Earth's surface and the clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to atmosphere. Certain substances in the atmosphere, chiefly cloud droplets and water vapor, but also carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, and chlorofluorocarbons, absorb this infrared, and re-radiate it in all directions including back to Earth. Thus, the greenhouse effect keeps the atmosphere and surface much warmer than if the infrared absorbers were absent from the atmosphere.
Is there an answer to this question: What keeps the atmosphere and surface re-radiated?

Answer: unanswerable

Problem: British Empire:

Most former British colonies and protectorates are among the 53 member states of the Commonwealth of Nations, a non-political, voluntary association of equal members, comprising a population of around 2.2 billion people.
