Input: Read this: The assumption that black-body radiation is thermal leads to an accurate prediction: the total amount of emitted energy goes up with the temperature according to a definite rule, the StefanBoltzmann law (187984). But it was also known that the colour of the light given off by a hot object changes with the temperature, so that "white hot" is hotter than "red hot". Nevertheless, Wilhelm Wien discovered the mathematical relationship between the peaks of the curves at different temperatures, by using the principle of adiabatic invariance. At each different temperature, the curve is moved over by Wien's displacement law (1893). Wien also proposed an approximation for the spectrum of the object, which was correct at high frequencies (short wavelength) but not at low frequencies (long wavelength). It still was not clear why the spectrum of a hot object had the form that it has (see diagram).
Question: What characteristic of the light emitted by a hot object changes with temperature?

Output: the colour of the light given off

Input: Read this: City and Guilds College was founded in 1876 from a meeting of 16 of the City of London's livery companies for the Advancement of Technical Education (CGLI), which aimed to improve the training of craftsmen, technicians, technologists, and engineers. The two main objectives were to create a Central Institution in London and to conduct a system of qualifying examinations in technical subjects. Faced with their continuing inability to find a substantial site, the Companies were eventually persuaded by the Secretary of the Science and Art Department, General Sir John Donnelly (who was also a Royal Engineer) to found their institution on the eighty-seven acre (350,000 m) site at South Kensington bought by the 1851 Exhibition Commissioners (for GBP 342,500) for 'purposes of art and science' in perpetuity. The latter two colleges were incorporated by Royal Charter into the Imperial College of Science and Technology and the CGLI Central Technical College was renamed the City and Guilds College in 1907, but not incorporated into Imperial College until 1910.
Question: How large was the land (in acres) that the institution was founded on?

Output: eighty-seven

Input: Read this: On 1 February 1908, the king Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luis Filipe, Duke of Braganza, were murdered in Lisbon. Under his rule, Portugal had twice been declared bankrupt on 14 June 1892, and again on 10 May 1902 causing social turmoil, economic disturbances, protests, revolts and criticism of the monarchy. Manuel II of Portugal became the new king, but was eventually overthrown by the 5 October 1910 revolution, which abolished the regime and instated republicanism in Portugal. Political instability and economic weaknesses were fertile ground for chaos and unrest during the Portuguese First Republic. These conditions would lead to the failed Monarchy of the North, 28 May 1926 coup d'etat, and the creation of the National Dictatorship (Ditadura Nacional).
Question: On what day were King Dom Carlos I and and his heir, Prince Royal Dom Luis Filipe, Duke of Braganza, murdered?

Output: 1 February 1908

Input: Read this: Inns are buildings where travellers can seek lodging and, usually, food and drink. They are typically located in the country or along a highway. In Europe, they possibly first sprang up when the Romans built a system of roads two millennia ago.[citation needed] Some inns in Europe are several centuries old. In addition to providing for the needs of travellers, inns traditionally acted as community gathering places.
Question: What road is an inn often located near?

Output:
highway
