Input: Read this: After forming partnerships with multinational corporations such as Sprint, ITT and Telenor, these firms now offer the cheapest and clearest phone calls in Africa. These Somali telecommunication companies also provide services to every city, town and hamlet in Somalia. There are presently around 25 mainlines per 1,000 persons, and the local availability of telephone lines (tele-density) is higher than in neighboring countries; three times greater than in adjacent Ethiopia. Prominent Somali telecommunications companies include Somtel Network, Golis Telecom Group, Hormuud Telecom, Somafone, Nationlink, Netco, Telcom and Somali Telecom Group. Hormuud Telecom alone grosses about $40 million a year. Despite their rivalry, several of these companies signed an interconnectivity deal in 2005 that allows them to set prices, maintain and expand their networks, and ensure that competition does not get out of control.
Question: Sprint, ITT, and Telenor are examples of what?

Output: multinational corporations


QUES: With nitrides containing aluminium, most often AlGaN and AlGaInN, even shorter wavelengths are achievable. Ultraviolet LEDs in a range of wavelengths are becoming available on the market. Near-UV emitters at wavelengths around 375–395 nm are already cheap and often encountered, for example, as black light lamp replacements for inspection of anti-counterfeiting UV watermarks in some documents and paper currencies. Shorter-wavelength diodes, while substantially more expensive, are commercially available for wavelengths down to 240 nm. As the photosensitivity of microorganisms approximately matches the absorption spectrum of DNA, with a peak at about 260 nm, UV LED emitting at 250–270 nm are to be expected in prospective disinfection and sterilization devices. Recent research has shown that commercially available UVA LEDs (365 nm) are already effective disinfection and sterilization devices. UV-C wavelengths were obtained in laboratories using aluminium nitride (210 nm), boron nitride (215 nm) and diamond (235 nm).

What is the range of wavelengths for cheap UV LEDs?
What is the answer?
ANS: 375–395 nm


QUES: In May 1948, following the British withdrawal, King Farouk sent the Egyptian army into Palestine, with Nasser serving in the 6th Infantry Battalion. During the war, he wrote of the Egyptian army's unpreparedness, saying "our soldiers were dashed against fortifications". Nasser was deputy commander of the Egyptian forces that secured the Faluja pocket. On 12 July, he was lightly wounded in the fighting. By August, his brigade was surrounded by the Israeli Army. Appeals for help from Jordan's Arab Legion went unheeded, but the brigade refused to surrender. Negotiations between Israel and Egypt finally resulted in the ceding of Faluja to Israel. According to veteran journalist Eric Margolis, the defenders of Faluja, "including young army officer Gamal Abdel Nasser, became national heroes" for enduring Israeli bombardment while isolated from their command.
How badly was Nasser wounded?

ANS: lightly


Post-war, Devonport Dockyard was kept busy refitting aircraft carriers such as the Ark Royal and, later, nuclear submarines while new light industrial factories were constructed in the newly zoned industrial sector attracting rapid growth of the urban population. The army had substantially left the city by 1971, with barracks pulled down in the 1960s, however the city remains home to the 42 Commando of the Royal Marines.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): By what year was the greater part of the army presence in Plymouth gone?
Ah, so.. 1971


Question: At present the Alps are one of the more popular tourist destinations in the world with many resorts such Oberstdorf, in Bavaria, Saalbach in Austria, Davos in Switzerland, Chamonix in France, and Cortina d'Ampezzo in Italy recording more than a million annual visitors. With over 120 million visitors a year tourism is integral to the Alpine economy with much it coming from winter sports although summer visitors are an important component of the tourism industry.
Try to answer this question if possible: What's one of the most popular tourist destinations in the world? 
Answer: the Alps


Context and question: During the tumultuous 14th century, disputes within the leadership of the Church led to the Avignon Papacy of 1305–78, also called the "Babylonian Captivity of the Papacy" (a reference to the Babylonian captivity of the Jews), and then to the Great Schism, lasting from 1378 to 1418, when there were two and later three rival popes, each supported by several states. Ecclesiastical officials convened at the Council of Constance in 1414, and in the following year the council deposed one of the rival popes, leaving only two claimants. Further depositions followed, and in November 1417 the council elected Martin V (pope 1417–31) as pope.
What is another term for the Avignon Papacy?
Answer:
Babylonian Captivity of the Papacy
