Problem: Please answer a question about the following article about Insect:
There are many different patterns of gas exchange demonstrated by different groups of insects. Gas exchange patterns in insects can range from continuous and diffusive ventilation, to discontinuous gas exchange.:65–68 During continuous gas exchange, oxygen is taken in and carbon dioxide is released in a continuous cycle. In discontinuous gas exchange, however, the insect takes in oxygen while it is active and small amounts of carbon dioxide are released when the insect is at rest. Diffusive ventilation is simply a form of continuous gas exchange that occurs by diffusion rather than physically taking in the oxygen. Some species of insect that are submerged also have adaptations to aid in respiration. As larvae, many insects have gills that can extract oxygen dissolved in water, while others need to rise to the water surface to replenish air supplies which may be held or trapped in special structures.
What kind of exchange is demonstrated by different insects?
A: gas exchange

Of the 80 torch-bearers in London, Sir Steve Redgrave, who started the relay, mentioned to the media that he had received e-mailed pleas to boycott the event and could "see why they would like to make an issue" of it. Francesca Martinez and Richard Vaughan refused to carry the torch, while Konnie Huq decided to carry it and also speak out against China. The pro-Tibetan Member of Parliament Norman Baker asked all bearers to reconsider. Amid pressure from both directions, Prime Minister Gordon Brown welcomed the torch outside 10 Downing Street without holding or touching it. The London relay saw the torch surrounded by what the BBC described as "a mobile protective ring." Protests began as soon as Redgrave started the event, leading to at least thirty-five arrests. In Ladbroke Grove a demonstrator attempted to snatch the torch from Konnie Huq in a momentary struggle, and in a separate incident, a fire extinguisher was set off near the torch. The Chinese ambassador carried the torch through Chinatown after an unpublicized change to the route amid security concerns. The torch made an unscheduled move onto a bus along Fleet Street amid security concerns and efforts to evade the protesters. In an effort to counter the pro-Tibet protesters and show their support for the 2008 Beijing Olympics, more than 2,000 Chinese also gathered on the torch route and demonstrated with signs, banners and Chinese flags. A large number of supporters were concentrated in Trafalgar Square, displaying the Olympic slogan "One World, One Dream".

How many people carried the torch in England for the 2008 Olympics?
Answer: 80


Problem: About 75% of the population is employed in subsistence agriculture upon Swazi Nation Land (SNL). In contrast with the commercial farms, Swazi Nation Land suffers from low productivity and investment. This dual nature of the Swazi economy, with high productivity in textile manufacturing and in the industrialised agricultural TDLs on the one hand, and declining productivity subsistence agriculture (on SNL) on the other, may well explain the country's overall low growth, high inequality and unemployment.
Outside of agriculture what provides to the Swazi economy?
The answer is the following: textile manufacturing

Input: Eritrea
In 1888, the Italian administration launched its first development projects in the new colony. The Eritrean Railway was completed to Saati in 1888, and reached Asmara in the highlands in 1911. The Asmara–Massawa Cableway was the longest line in the world during its time, but was later dismantled by the British in World War II. Besides major infrastructural projects, the colonial authorities invested significantly in the agricultural sector. It also oversaw the provision of urban amenities in Asmara and Massawa, and employed many Eritreans in public service, particularly in the police and public works departments. Thousands of Eritreans were concurrently enlisted in the army, serving during the Italo-Turkish War in Libya as well as the First and second Italo-Abyssinian Wars.

In what areas of public service were Eritreans particularly employed?
Output: police and public works departments


Problem: Please answer a question about the following article about Gothic architecture:
It was principally the widespread introduction of a single feature, the pointed arch, which was to bring about the change that separates Gothic from Romanesque. The technological change permitted a stylistic change which broke the tradition of massive masonry and solid walls penetrated by small openings, replacing it with a style where light appears to triumph over substance. With its use came the development of many other architectural devices, previously put to the test in scattered buildings and then called into service to meet the structural, aesthetic and ideological needs of the new style. These include the flying buttresses, pinnacles and traceried windows which typify Gothic ecclesiastical architecture. But while pointed arch is so strongly associated with the Gothic style, it was first used in Western architecture in buildings that were in other ways clearly Romanesque, notably Durham Cathedral in the north of England, Monreale Cathedral and Cathedral of Cefalù in Sicily, Autun Cathedral in France.
What is the name of the cathedral in Northern England that first displayed the use of the pointed arch?
A:
Durham Cathedral
