Article: On September 15, 2007, Witon Barry (of the Tobolar Copra processing plant in the Marshall Islands capital of Majuro) said power authorities, private companies, and entrepreneurs had been experimenting with coconut oil as alternative to diesel fuel for vehicles, power generators, and ships. Coconut trees abound in the Pacific's tropical islands. Copra, the meat of the coconut, yields coconut oil (1 liter for every 6 to 10 coconuts). In 2009, a 57 kW solar power plant was installed, the largest in the Pacific at the time, including New Zealand. It is estimated that 330 kW of solar and 450 kW of wind power would be required to make the College of the Marshall Islands energy self-sufficient. Marshalls Energy Company (MEC), a government entity, provides the islands with electricity. In 2008, 420 solar home systems of 200 Wp each were installed on Ailinglaplap Atoll, sufficient for limited electricity use.

Question: How many coconuts are required to produce 1 liter of coconut oil?
Ans: 6 to 10


Article: Active solar techniques use photovoltaics, concentrated solar power, solar thermal collectors, pumps, and fans to convert sunlight into useful outputs. Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies.

Question: What does an active solar technique do?
Ans: increase the supply of energy


Article: The Bovington signal course's director reported that Gaddafi successfully overcame problems learning English, displaying a firm command of voice procedure. Noting that Gaddafi's favourite hobbies were reading and playing football, he thought him an "amusing officer, always cheerful, hard-working, and conscientious." Gaddafi disliked England, claiming British Army officers racially insulted him and finding it difficult adjusting to the country's culture; asserting his Arab identity in London, he walked around Piccadilly wearing traditional Libyan robes. He later related that while he travelled to England believing it more advanced than Libya, he returned home "more confident and proud of our values, ideals and social character."

Question: Where did Gaddafi's signal course take place?
Ans:
Bovington
