Problem: Bird migration:

Birds fly at varying altitudes during migration. An expedition to Mt. Everest found skeletons of northern pintail Anas acuta and black-tailed godwit Limosa limosa at 5,000 m (16,000 ft) on the Khumbu Glacier. Bar-headed geese Anser indicus have been recorded by GPS flying at up to 6,540 metres (21,460 ft) while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird. Anecdotal reports of them flying much higher have yet to be corroborated with any direct evidence. Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in landbirds. However most bird migration is in the range of 150 to 600 m (490 to 1,970 ft). Bird strike aviation records from the United States show most collisions occur below 600 m (2,000 ft) and almost none above 1,800 m (5,900 ft).

Which birds have the highest rates of climb to altitude?
---
A: Bar-headed geese Anser indicus

Problem: The symbol $, usually written before the numerical amount, is used for the U.S. dollar (as well as for many other currencies). The sign was the result of a late 18th-century evolution of the scribal abbreviation "ps" for the peso, the common name for the Spanish dollars that were in wide circulation in the New World from the 16th to the 19th centuries. These Spanish pesos or dollars were minted in Spanish America, namely in Mexico City, Potosi, Bolivia; and Lima, Peru. The p and the s eventually came to be written over each other giving rise to $.
What abbreviation was the dollar sign based off of?

Answer: ps

In October 2014, the trial of six senior staff and journalists at The Sun newspaper began. All six were charged with conspiring to commit misconduct in a public office. They included The Sun's head of news Chris Pharo, who faced six charges, while ex-managing editor Graham Dudman and ex-Sun deputy news editor Ben O'Driscoll were accused of four charges each. Thames Valley district reporter Jamie Pyatt and picture editor John Edwards were charged with three counts each, while ex-reporter John Troup was accused of two counts. The trial related to illegal payments allegedly made to public officials, with prosecutors saying the men conspired to pay officials from 200211, including police, prison officers and soldiers. They were accused of buying confidential information about the Royal Family, public figures and prison inmates. They all denied the charges. On 16 January 2015, Troup and Edwards were cleared by the jury of all charges against them. The jury also partially cleared O'Driscoll and Dudman but continued deliberating over other counts faced by them, as well as the charges against Pharo and Pyatt. On 21 January 2015, the jury told the court that it was unable to reach unanimous verdicts on any of the outstanding charges and was told by the judge, Richard Marks, that he would accept majority verdicts. Shortly afterwards, one of the jurors sent a note to the judge and was discharged. The judge told the remaining 11 jurors that their colleague had been "feeling unwell and feeling under a great deal of pressure and stress from the situation you are in", and that under the circumstances he was prepared to accept majority verdicts of "11 to zero or 10 to 1". On 22 January 2015, the jury was discharged after failing to reach verdicts on the outstanding charges. The Crown Prosecution Service (CPS) announced that it would seek a retrial.
What was at issue in the 2014 trial?
A: illegal payments allegedly made to public officials

Context and question: Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. He then published his observations in a series of letters to the Royal Society of London. Bacteria were Leeuwenhoek's most remarkable microscopic discovery. They were just at the limit of what his simple lenses could make out and, in one of the most striking hiatuses in the history of science, no one else would see them again for over a century. Only then were his by-then-largely-forgotten observations of bacteria as opposed to his famous "animalcules" (spermatozoa) taken seriously.
Who discovered bacteria?
Answer: Dutch microscopist Antonie van Leeuwenhoek

Question: Switzerland voted against membership in the European Economic Area in a referendum in December 1992 and has since maintained and developed its relationships with the European Union (EU) and European countries through bilateral agreements. In March 2001, the Swiss people refused in a popular vote to start accession negotiations with the EU. In recent years, the Swiss have brought their economic practices largely into conformity with those of the EU in many ways, in an effort to enhance their international competitiveness. The economy grew at 3% in 2010, 1.9% in 2011, and 1% in 2012. Full EU membership is a long-term objective of some in the Swiss government, but there is considerable popular sentiment against this supported by the conservative SVP party. The western French-speaking areas and the urban regions of the rest of the country tend to be more pro-EU, however with far from any significant share of the population.
Is there an answer to this question: How much did the Swiss economy grow in 2010?

Answer: 3%

Question: The arrangement of plates and dielectric has many variations depending on the desired ratings of the capacitor. For small values of capacitance (microfarads and less), ceramic disks use metallic coatings, with wire leads bonded to the coating. Larger values can be made by multiple stacks of plates and disks. Larger value capacitors usually use a metal foil or metal film layer deposited on the surface of a dielectric film to make the plates, and a dielectric film of impregnated paper or plastic these are rolled up to save space. To reduce the series resistance and inductance for long plates, the plates and dielectric are staggered so that connection is made at the common edge of the rolled-up plates, not at the ends of the foil or metalized film strips that comprise the plates.
Is there an answer to this question: What order of magnitude of capacitance is suitable for capacitors comprised of ceramic disks with metallic coatings?

Answer:
microfarads and less
