Example Input: How did the guns function?, Context: After the Dambusters raid in 1943 an entirely new system was developed that was required to knock down any low-flying aircraft with a single hit. The first attempt to produce such a system used a 50 mm gun, but this proved inaccurate and a new 55 mm gun replaced it. The system used a centralised control system including both search and targeting radar, which calculated the aim point for the guns after considering windage and ballistics, and then sent electrical commands to the guns, which used hydraulics to point themselves at high speeds. Operators simply fed the guns and selected the targets. This system, modern even by today's standards, was in late development when the war ended.
Example Output: a centralised control system

Example Input: Where can you go in Paris today to visit authentic cafes?, Context: In addition to the classical restaurants, Paris has several other kinds of traditional eating places. The café arrived in Paris in the 17th century, when the beverage was first brought from Turkey, and by the 18th century Parisian cafés were centres of the city's political and cultural life. The Cafe Procope on the Left Bank dates from this period. In the 20th century, the cafés of the Left Bank, especially Café de la Rotonde and Le Dôme Café in Montparnasse and Café de Flore and Les Deux Magots on Boulevard Saint Germain, all still in business, were important meeting places for painters, writers and philosophers. A bistro is a type of eating place loosely defined as a neighbourhood restaurant with a modest decor and prices and a regular clientele and a congenial atmosphere. Its name is said to have come in 1814 from the Russian soldiers who occupied the city; "bistro" means "quickly" in Russian, and they wanted their meals served rapidly so they could get back their encampment. Real bistros are increasingly rare in Paris, due to rising costs, competition from cheaper ethnic restaurants, and different eating habits of Parisian diners. A brasserie originally was a tavern located next to a brewery, which served beer and food at any hour. Beginning with the Paris Exposition of 1867; it became a popular kind of restaurant which featured beer and other beverages served by young women in the national costume associated with the beverage, particular German costumes for beer. Now brasseries, like cafés, serve food and drinks throughout the day.
