Problem: With a population of 518,000, Hanover is a major centre of Northern Germany and the country's thirteenth largest city. Hanover also hosts annual commercial trade fairs such as the Hanover Fair and the CeBIT. Every year Hanover hosts the Schutzenfest Hannover, the world's largest marksmen's festival, and the Oktoberfest Hannover, the second largest Oktoberfest in the world (beside Oktoberfest of Blumenau). In 2000, Hanover hosted the world fair Expo 2000. The Hanover fairground, due to numerous extensions, especially for the Expo 2000, is the largest in the world. Hanover is of national importance because of its universities and medical school, its international airport and its large zoo. The city is also a major crossing point of railway lines and highways (Autobahnen), connecting European main lines in both the east-west (BerlinRuhr area) and north-south (HamburgMunich, etc.) directions.
In which year did Hanover host the Expo?
The answer is the following: 2000

Input: Alexander Graham Bell
Bell began a series of public demonstrations and lectures to introduce the new invention to the scientific community as well as the general public. A short time later, his demonstration of an early telephone prototype at the 1876 Centennial Exposition in Philadelphia brought the telephone to international attention. Influential visitors to the exhibition included Emperor Pedro II of Brazil. Later Bell had the opportunity to demonstrate the invention personally to Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, as well as to Queen Victoria, who had requested a private audience at Osborne House, her Isle of Wight home. She called the demonstration "most extraordinary". The enthusiasm surrounding Bell's public displays laid the groundwork for universal acceptance of the revolutionary device.

Which Queen did Bell present his invention to?
Output: Victoria

Input: Article: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.

Now answer this question: Oxygen from what kind of fossil were used to date the Hirnantian faunal stage?

Output: brachiopods

Article: During the initial punk era, a variety of entrepreneurs interested in local punk-influenced music scenes began founding independent record labels, including Rough Trade (founded by record shop owner Geoff Travis) and Factory (founded by Manchester-based television personality Tony Wilson). By 1977, groups began pointedly pursuing methods of releasing music independently , an idea disseminated in particular by the Buzzcocks' release of their Spiral Scratch EP on their own label as well as the self-released 1977 singles of Desperate Bicycles. These DIY imperatives would help form the production and distribution infrastructure of post-punk and the indie music scene that later blossomed in the mid-1980s.

Question: Who founded Factory?
Ans: Tony Wilson

Input: Lighting
Major reductions in the cost of lighting occurred with the discovery of whale oil and kerosene. Gas lighting was economical enough to power street lights in major cities starting in the early 1800s, and was also used in some commercial buildings and in the homes of wealthy people. The gas mantle boosted the luminosity of utility lighting and of kerosene lanterns. The next major drop in price came about with the incandescent light bulb powered by electricity.

What type of lighting was powered by electricity?
Output:
incandescent light
