Q: Extract the answer to the question from the following context. Question: Who prefers the term "black"? Context: In 1988, the civil rights leader Jesse Jackson urged Americans to use instead the term "African American" because it had a historical cultural base and was a construction similar to terms used by European descendants, such as German American, Italian American, etc. Since then, African American and black have often had parallel status. However, controversy continues over which if any of the two terms is more appropriate. Maulana Karenga argues that the term African-American is more appropriate because it accurately articulates their geographical and historical origin.[citation needed] Others have argued that "black" is a better term because "African" suggests foreignness, although Black Americans helped found the United States. Still others believe that the term black is inaccurate because African Americans have a variety of skin tones. Some surveys suggest that the majority of Black Americans have no preference for "African American" or "Black", although they have a slight preference for "black" in personal settings and "African American" in more formal settings.
A: Others

Q: Extract the answer to the question from the following context. Question: When will renewable energy provide over 1/5 of all energy? Context: The incentive to use 100% renewable energy, for electricity, transport, or even total primary energy supply globally, has been motivated by global warming and other ecological as well as economic concerns. The Intergovernmental Panel on Climate Change has said that there are few fundamental technological limits to integrating a portfolio of renewable energy technologies to meet most of total global energy demand. In reviewing 164 recent scenarios of future renewable energy growth, the report noted that the majority expected renewable sources to supply more than 17% of total energy by 2030, and 27% by 2050; the highest forecast projected 43% supplied by renewables by 2030 and 77% by 2050. Renewable energy use has grown much faster than even advocates anticipated. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Also, Professors S. Pacala and Robert H. Socolow have developed a series of "stabilization wedges" that can allow us to maintain our quality of life while avoiding catastrophic climate change, and "renewable energy sources," in aggregate, constitute the largest number of their "wedges."
A: 2050

Q: Extract the answer to the question from the following context. Question: What led to Tang victory over the Sui Context: Zhejiang, as the heartland of the Jiangnan (Yangtze River Delta), remained the wealthiest area during the Six Dynasties (220 or 222589), Sui, and Tang. After being incorporated into the Sui dynasty, its economic richness was used for the Sui dynasty's ambitions to expand north and south, particularly into Korea and Vietnam. The plan led the Sui dynasty to restore and expand the network which became the Grand Canal of China. The Canal regularly transported grains and resources from Zhejiang, through its metropolitan center Hangzhou (and its hinterland along both the Zhe River and the shores of Hangzhou Bay), and from Suzhou, and thence to the North China Plain. The debacle of the Korean war led to Sui's overthrow by the Tang, who then presided over a centuries-long golden age for the country. Zhejiang was an important economic center of the empire's Jiangnan East Circuit and was considered particularly prosperous. Throughout the Tang dynasty, The Grand Canal had remained effective, transporting grains and material resources to North China plain and metropolitan centers of the empire. As the Tang Dynasty disintegrated, Zhejiang constituted most of the territory of the regional kingdom of Wuyue.
A: the Korean war

Q: Extract the answer to the question from the following context. Question: Which of the following describes Richard Cobden: Radical MP, modern architect, or Prime MInister? Context: The 19th-century Liberal Prime Minister William Ewart Gladstone considered Burke "a magazine of wisdom on Ireland and America" and in his diary recorded: "Made many extracts from Burkesometimes almost divine". The Radical MP and anti-Corn Law activist Richard Cobden often praised Burke's Thoughts and Details on Scarcity. The Liberal historian Lord Acton considered Burke one of the three greatest Liberals, along with William Gladstone and Thomas Babington Macaulay. Lord Macaulay recorded in his diary: "I have now finished reading again most of Burke's works. Admirable! The greatest man since Milton". The Gladstonian Liberal MP John Morley published two books on Burke (including a biography) and was influenced by Burke, including his views on prejudice. The Cobdenite Radical Francis Hirst thought Burke deserved "a place among English libertarians, even though of all lovers of liberty and of all reformers he was the most conservative, the least abstract, always anxious to preserve and renovate rather than to innovate. In politics he resembled the modern architect who would restore an old house instead of pulling it down to construct a new one on the site". Burke's Reflections on the Revolution in France was controversial at the time of its publication, but after his death, it was to become his best known and most influential work, and a manifesto for Conservative thinking.
A:
Radical MP
