Article: The Portuguese found the island uninhabited, with an abundance of trees and fresh water. They imported livestock, fruit trees and vegetables, and built a chapel and one or two houses. Though they formed no permanent settlement, the island was an important rendezvous point and source of food for ships travelling from Asia to Europe, and frequently sick mariners were left on the island to recover, before taking passage on the next ship to call on the island.

Question: What was the island a source of for ships travelling from Asia to Europe?
Ans: food


Article: Daniel Gralath was the first to combine several jars in parallel into a "battery" to increase the charge storage capacity. Benjamin Franklin investigated the Leyden jar and came to the conclusion that the charge was stored on the glass, not in the water as others had assumed. He also adopted the term "battery", (denoting the increasing of power with a row of similar units as in a battery of cannon), subsequently applied to clusters of electrochemical cells. Leyden jars were later made by coating the inside and outside of jars with metal foil, leaving a space at the mouth to prevent arcing between the foils.[citation needed] The earliest unit of capacitance was the jar, equivalent to about 1.11 nanofarads.

Question: How many nanofarads did the earliest unit of capacitance equate to? 
Ans: 1.11 nanofarads


Article: By the end of 1957, Nasser nationalized all remaining British and French assets in Egypt, including the tobacco, cement, pharmaceutical, and phosphate industries. When efforts to offer tax incentives and attract outside investments yielded no tangible results, he nationalized more companies and made them a part of his economic development organization. He stopped short of total government control: two-thirds of the economy was still in private hands. This effort achieved a measure of success, with increased agricultural production and investment in industrialization. Nasser initiated the Helwan steelworks, which subsequently became Egypt's largest enterprise, providing the country with product and tens of thousands of jobs. Nasser also decided to cooperate with the Soviet Union in the construction of the Aswan Dam to replace the withdrawal of US funds.

Question: What entity did Nasser spearhead that was a boon for Egypt's economy?
Ans: Helwan steelworks


Article: Aristotle however suggested that swallows and other birds hibernated. This belief persisted as late as 1878, when Elliott Coues listed the titles of no less than 182 papers dealing with the hibernation of swallows. Even the "highly observant" Gilbert White, in his posthumously published 1789 The Natural History of Selborne, quoted a man's story about swallows being found in a chalk cliff collapse "while he was a schoolboy at Brighthelmstone", though the man denied being an eyewitness. However, he also writes that "as to swallows being found in a torpid state during the winter in the Isle of Wight or any part of this country, I never heard any such account worth attending to", and that if early swallows "happen to find frost and snow they immediately withdraw for a time—a circumstance this much more in favour of hiding than migration", since he doubts they would "return for a week or two to warmer latitudes".

Question: Who wrote 182 papers dealing with the hibernation of swallows?
Ans:
Elliott Coues
