Input: Read this: 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.
Question: Analysts expect the market to triple by what year?

Output: 2030

Input: Read this: Labour went on to win the 1950 general election, but with a much reduced majority of five seats. Soon afterwards, defence became a divisive issue within the party, especially defence spending (which reached a peak of 14% of GDP in 1951 during the Korean War), straining public finances and forcing savings elsewhere. The Chancellor of the Exchequer, Hugh Gaitskell, introduced charges for NHS dentures and spectacles, causing Bevan, along with Harold Wilson (then President of the Board of Trade), to resign over the dilution of the principle of free treatment on which the NHS had been established.
Question: What was not a principle the NHS was based on?

Output: unanswerable

Input: Read this: National Basketball Association teams play eight preseason games per year. Today, NBA teams almost always play each other in the preseason, but mainly at neutral sites within their market areas in order to allow those who can't usually make a trip to a home team's arena during the regular season to see a game close to home; for instance the Minnesota Timberwolves will play games in arenas in North Dakota and South Dakota, while the Phoenix Suns schedule one exhibition game outdoors at Indian Wells Tennis Garden in Indian Wells, California yearly, the only such instance an NBA game takes place in an outdoor venue.
Question: What venue do the Suns play at in Indian Wells?

Output: Indian Wells Tennis Garden

Input: Read this: Raleigh is located in the northeast central region of North Carolina, where the Piedmont and Atlantic Coastal Plain regions meet. This area is known as the "fall line" because it marks the elevation inland at which waterfalls begin to appear in creeks and rivers. As a result, most of Raleigh features gently rolling hills that slope eastward toward the state's flat coastal plain. Its central Piedmont location situates Raleigh about two hours west of Atlantic Beach, North Carolina, by car and four hours east of the Great Smoky Mountains. The city is 155 miles (249 km) south of Richmond, Virginia, 263 miles (423 km) south of Washington, D.C., and 150 miles (240 km) northeast of Charlotte, North Carolina.
Question: What type of geography is in Raleigh?

Output:
gently rolling hills that slope eastward toward the state's flat coastal plain.
