Input: Read this: Soon after the passing of the 1931 Act, in the book published on the occasion of the Institute's centenary celebration in 1934, Harry Barnes, FRIBA, Chairman of the Registration Committee, mentioned that ARCUK could not be a rival of any architectural association, least of all the RIBA, given the way ARCUK was constituted. Barnes commented that the Act's purpose was not protecting the architectural profession, and that the legitimate interests of the profession were best served by the (then) architectural associations in which some 80 per cent of those practising architecture were to be found.

Input: Read this: Unarmed fox hunting on horseback with hounds is the type of hunting most closely associated with the United Kingdom; in fact, "hunting" without qualification implies fox hunting. What in other countries is called "hunting" is called "shooting" (birds) or "stalking" (deer) in Britain. Originally a form of vermin control to protect livestock, fox hunting became a popular social activity for newly wealthy upper classes in Victorian times and a traditional rural activity for riders and foot followers alike. Similar to fox hunting in many ways is the chasing of hares with hounds. Pairs of Sight hounds (or long-dogs), such as greyhounds, may be used to pursue a hare in coursing, where the greyhounds are marked as to their skill in coursing the hare (but are not intended to actually catch it), or the hare may be pursued with scent hounds such as beagles or harriers. Other sorts of foxhounds may also be used for hunting stags (deer) or mink. Deer stalking with rifles is carried out on foot without hounds, using stealth.
Question: Why were foxes originally hunted?

Output: form of vermin control to protect livestock

Input: Read this: The Boulton Paul Defiant, despite its poor performance during daylight engagements, was a much better night fighter. It was faster, able to catch the bombers and its configuration of four machine guns in a turret could (much like German night fighters in 19431945 with Schrage Musik) engage the unsuspecting German bomber from beneath. Attacks from below offered a larger target, compared to attacking tail-on, as well as a better chance of not being seen by the bomber (so less chance of evasion), as well as greater likelihood of detonating its bombload. In subsequent months a steady number of German bombers would fall to night fighters.
Question: How could aircraft engage bombers when fitted with a turret?

Output: engage the unsuspecting German bomber from beneath

Input: Read this: The outcome of the First World War was disastrous for both the German Reich and the Russian Soviet Federative Socialist Republic. During the war, the Bolsheviks struggled for survival, and Vladimir Lenin recognised the independence of Finland, Estonia, Latvia, Lithuania and Poland. Moreover, facing a German military advance, Lenin and Trotsky were forced to enter into the Treaty of Brest-Litovsk, which ceded massive western Russian territories to the German Empire. After Germany's collapse, a multinational Allied-led army intervened in the Russian Civil War (191722).
