Input: Philosophy of space and time
In the classical case, the invariance, or symmetry, group and the covariance group coincide, but, interestingly enough, they part ways in relativistic physics. The symmetry group of the general theory of relativity includes all differentiable transformations, i.e., all properties of an object are dynamical, in other words there are no absolute objects. The formulations of the general theory of relativity, unlike those of classical mechanics, do not share a standard, i.e., there is no single formulation paired with transformations. As such the covariance group of the general theory of relativity is just the covariance group of every theory.

Which theory does the relativity depart from?
Output: classical mechanics


Input: Article: During World War II, the British at Bletchley Park achieved a number of successes at breaking encrypted German military communications. The German encryption machine, Enigma, was first attacked with the help of the electro-mechanical bombes. To crack the more sophisticated German Lorenz SZ 40/42 machine, used for high-level Army communications, Max Newman and his colleagues commissioned Flowers to build the Colossus. He spent eleven months from early February 1943 designing and building the first Colossus. After a functional test in December 1943, Colossus was shipped to Bletchley Park, where it was delivered on 18 January 1944 and attacked its first message on 5 February.

Now answer this question: Who built the first Colossus in 1943?

Output: Flowers


Article: The marine life found here consists of anemones, urchins, sea cucumbers, and eels, which all live on the reefs along with turtles, conch and many varieties of marine fishes. The marine aquafauna is rich in conch, which has pearly-pink shells. Its meat is a favourite food supplement item and their shells are a collectors item. Other species of fish which are recorded close to the shore line in shallow waters are: sergeant majors, the blue chromis, brown chromis, surgeon fish; blue tangs and trumpet fish. On the shore are ghost crabs, which always live on the beach in small burrowed tunnels made in sand, and the hermit crabs, which live in land but lay eggs in water and which also eat garbage and sewerage. They spend some months in the sea during and after the hatching season.

Question: Where are surgeonfish found in St. Barts?
Ans: shallow waters


Here is a question about this article: Idris' government was increasingly unpopular by the latter 1960s; it had exacerbated Libya's traditional regional and tribal divisions by centralising the country's federal system in order to take advantage of the country's oil wealth, while corruption and entrenched systems of patronage were widespread throughout the oil industry. Arab nationalism was increasingly popular, and protests flared up following Egypt's 1967 defeat in the Six-Day War with Israel; allied to the western powers, Idris' administration was seen as pro-Israeli. Anti-western riots broke out in Tripoli and Benghazi, while Libyan workers shut down oil terminals in solidarity with Egypt. By 1969, the U.S. Central Intelligence Agency was expecting segments of Libya's armed forces to launch a coup. Although claims have been made that they knew of Gaddafi's Free Officers Movement, they have since claimed ignorance, stating that they were monitoring Abdul Aziz Shalhi's Black Boots revolutionary group.
What is the answer to this question: What sort of problems did the oil industry experience in Libya?
****
So... corruption and entrenched systems of patronage were widespread throughout the oil industry


The problem: Answer a question about this article:
A novelty shop called Au Bon Marché had been founded in Paris in 1838 to sell lace, ribbons, sheets, mattresses, buttons, umbrellas and other assorted goods. It originally had four departments, twelve employees, and a floor space of three hundred meters. The entrepreneur Aristide Boucicaut became a partner in 1852, and changed the marketing plan, instituting fixed prices and guarantees that allowed exchanges and refunds, advertising, and a much wider variety of merchandise. The annual income of the store increased from 500,000 francs in 1852 to five million in 1860. In 1869 he built much larger building at 24 rue de Sèvres on the Left Bank, and enlarged the store again in 1872, with help from the engineering firm of Gustave Eiffel, creator of the Eiffel Tower. The income rose from twenty million francs in 1870 to 72 million at the time of the Boucicaut's death in 1877. The floor space had increased from three hundred square meters in 1838 to fifty thousand, and the number of employees had increased from twelve in 1838 to 1788 in 1879. Boucicaut was famous for his marketing innovations; a reading room for husbands while their wives shopped; extensive newspaper advertising; entertainment for children; and six million catalogs sent out to customers. By 1880 half the employees were women; unmarried women employees lived in dormitories on the upper floors.
Who became a partner to this store in 1852 and drastically changed operations?
****
The answer: Aristide Boucicaut


The problem: Answer a question about this article:
The work of children was important in pre-industrial societies, as children needed to provide their labour for their survival and that of their group. Pre-industrial societies were characterised by low productivity and short life expectancy, preventing children from participating in productive work would be more harmful to their welfare and that of their group in the long run. In pre-industrial societies, there was little need for children to attend school. This is especially the case in non literate societies. Most pre-industrial skill and knowledge were amenable to being passed down through direct mentoring or apprenticing by competent adults.
Was there a period when child labour was essential?
****
The answer:
pre-industrial societies
