question:
What is fundamental to the function of the airport that has yet to be obtained?, Context: The UK government has spent £250 million in the construction of the island's airport. Expected to be fully operational early 2016, it is expected to help the island towards self-sufficiency and encourage economic development, reducing dependence on British government aid. The airport is also expected to kick start the tourism industry, with up to 30,000 visitors expected annually. As of August, 2015 ticketing was postponed until an airline could be firmly designated.
answer:
airline


question:
If you had water and coal or wood fuel, what could be done?, Context: In 1781 James Watt patented a steam engine that produced continuous rotary motion. Watt's ten-horsepower engines enabled a wide range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. The stationary steam engine was a key component of the Industrial Revolution, allowing factories to locate where water power was unavailable. The atmospheric engines of Newcomen and Watt were large compared to the amount of power they produced, but high pressure steam engines were light enough to be applied to vehicles such as traction engines and the railway locomotives.
answer:
engines could be sited


question:
What do USAF operate?, Context: Specific concerns include a compounded inability for the Air Force to replace its aging fleet, and an overall reduction of strength and readiness. The USAF attempted to make these adjustments by primarily cutting the Air National Guard and Air Force Reserve aircraft fleets and their associated manpower, but Congress reversed this initiative and the majority of the lost manpower will come from the active forces. However, Congress did allow for $208 million of reprogramming from fleet modernization to enable some portion of the third of the grounded fleet to resume operations.
answer:

aging fleet
