Input: Read this: Oklahoma is the nation's third-largest producer of natural gas, fifth-largest producer of crude oil, and has the second-greatest number of active drilling rigs, and ranks fifth in crude oil reserves. While the state ranked eighth for installed wind energy capacity in 2011, it is at the bottom of states in usage of renewable energy, with 94 percent of its electricity being generated by non-renewable sources in 2009, including 25 percent from coal and 46 percent from natural gas. Oklahoma has no nuclear power. Ranking 13th for total energy consumption per capita in 2009, Oklahoma's energy costs were 8th lowest in the nation.
Question: How much of Oklahoma's electricity comes from non-renewable sources?

Output: 94 percent

Input: Read this: The typical image of migration is of northern landbirds, such as swallows (Hirundinidae) and birds of prey, making long flights to the tropics. However, many Holarctic wildfowl and finch (Fringillidae) species winter in the North Temperate Zone, in regions with milder winters than their summer breeding grounds. For example, the pink-footed goose Anser brachyrhynchus migrates from Iceland to Britain and neighbouring countries, whilst the dark-eyed junco Junco hyemalis migrates from subarctic and arctic climates to the contiguous United States and the American goldfinch from taiga to wintering grounds extending from the American South northwestward to Western Oregon. Migratory routes and wintering grounds are traditional and learned by young during their first migration with their parents. Some ducks, such as the garganey Anas querquedula, move completely or partially into the tropics. The European pied flycatcher Ficedula hypoleuca also follows this migratory trend, breeding in Asia and Europe and wintering in Africa.
Question: How do young learn migratory routes?

Output: during their first migration with their parents

Input: Read this: The Licensing Act 2003, which came into force on 24 November 2005, consolidated the many laws into a single Act. This allowed pubs in England and Wales to apply to the local council for the opening hours of their choice. It was argued that this would end the concentration of violence around 11.30 pm, when people had to leave the pub, making policing easier. In practice, alcohol-related hospital admissions rose following the change in the law, with alcohol involved in 207,800 admissions in 2006/7. Critics claimed that these laws would lead to "24-hour drinking". By the time the law came into effect, 60,326 establishments had applied for longer hours and 1,121 had applied for a licence to sell alcohol 24 hours a day. However nine months later many pubs had not changed their hours, although some stayed open longer at the weekend, but rarely beyond 1:00 am.
Question: How many pubs applied to be allowed to sell alcohol 24 hours a day?

Output: 1,121

Input: Read this: In March 2013, the Blackstone Group and Carl Icahn expressed interest in purchasing Dell. In April 2013, Blackstone withdrew their offer, citing deteriorating business. Other private equity firms such as KKR & Co. and TPG Capital declined to submit alternative bids for Dell, citing the uncertain market for personal computers and competitive pressures, so the "wide-open bidding war" never materialized. Analysts said that the biggest challenge facing Silver Lake would be to find an "exit strategy" to profit from its investment, which would be when the company would hold an IPO to go public again, and one warned "But even if you can get a $25bn enterprise value for Dell, it will take years to get out."
Question: What year did the Blackstone Group express interest in acquiring IBM?

Output:
unanswerable
