Here is a question about this article: In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
What is the answer to this question: How many years prior to Planck's study had the scientific community first discussed black body radiation?
****
So... forty

The problem: Answer a question about this article:
Apart from residences for upper and middle class households, sanitation is insufficient in most residential areas. Private flush toilets are too expensive for virtually all residents in townships due to their water consumption and installation cost. As a result, access to improved sanitation has not increased much since independence: In Namibia's rural areas 13% of the population had more than basic sanitation, up from 8% in 1990. Many of Namibia's inhabitants have to resort to "flying toilets", plastic bags to defecate which after use are flung into the bush. The use of open areas close to residential land to urinate and defecate is very common and has been identified as a major health hazard.
Most residential areas are insufficient in what area of Namibia?
****
The answer: sanitation

Problem: Please answer a question about the following article about London:
Some international railway services to Continental Europe were operated during the 20th century as boat trains, such as the Admiraal de Ruijter to Amsterdam and the Night Ferry to Paris and Brussels. The opening of the Channel Tunnel in 1994 connected London directly to the continental rail network, allowing Eurostar services to begin. Since 2007, high-speed trains link St. Pancras International with Lille, Paris, Brussels and European tourist destinations via the High Speed 1 rail link and the Channel Tunnel. The first high-speed domestic trains started in June 2009 linking Kent to London. There are plans for a second high speed line linking London to the Midlands, North West England, and Yorkshire.
When did local high speed rail service that linked London and Kent begin?
A: June 2009

Alternatively, or in addition to this practice, the members of an upper house may be indirectly elected by the government or legislature of the component states, as occurred in the United States prior to 1913, or be actual members or delegates of the state governments, as, for example, is the case in the German Bundesrat and in the Council of the European Union. The lower house of a federal legislature is usually directly elected, with apportionment in proportion to population, although states may sometimes still be guaranteed a certain minimum number of seats.

Can the members of the lower house be elected directly or indirectly?
Answer: directly

Problem: The Mature Indus civilisation flourished from about 2600 to 1900 BCE, marking the beginning of urban civilisation on the subcontinent. The civilisation included urban centres such as Dholavira, Kalibangan, Ropar, Rakhigarhi, and Lothal in modern-day India, as well as Harappa, Ganeriwala, and Mohenjo-daro in modern-day Pakistan. The civilisation is noted for its cities built of brick, roadside drainage system, and multistoreyed houses and is thought to have had some kind of municipal organization.
What kind of organization did the Mature Indus have?
The answer is the following: municipal

Input: Article: By 1640, the town's theocratic government and nine-square grid plan were in place, and the town was renamed Newhaven from Quinnipiac. However, the area north of New Haven remained Quinnipiac until 1678, when it was renamed Hamden. The settlement became the headquarters of the New Haven Colony. At the time, the New Haven Colony was separate from the Connecticut Colony, which had been established to the north centering on Hartford. One of the principal differences between the two colonies was that the New Haven colony was an intolerant theocracy that did not permit other churches to be established, while the Connecticut colony permitted the establishment of other churches.

Now answer this question: In what year was the northern area of New Haven renamed Hamden?

Output:
1678
