Problem: Please answer a question about the following article about BeiDou Navigation Satellite System:
Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit. This means that the system does not require a large constellation of satellites, but it also limits the coverage to areas on Earth where the satellites are visible. The area that can be serviced is from longitude 70°E to 140°E and from latitude 5°N to 55°N. A frequency of the system is 2491.75 MHz.
What service area is covered by the BeiDou-1 system?
A: from longitude 70°E to 140°E and from latitude 5°N to 55°N
Problem: Please answer a question about the following article about Buddhism:
Śuddhodana was determined to see his son become a king, so he prevented him from leaving the palace grounds. But at age 29, despite his father's efforts, Gautama ventured beyond the palace several times. In a series of encounters—known in Buddhist literature as the four sights—he learned of the suffering of ordinary people, encountering an old man, a sick man, a corpse and, finally, an ascetic holy man, apparently content and at peace with the world. These experiences prompted Gautama to abandon royal life and take up a spiritual quest.
At what age did Gautama venture out from the palace area?
A: 29
Problem: Please answer a question about the following article about Napoleon:
Before the formation of the Third Coalition, Napoleon had assembled an invasion force, the Armée d'Angleterre, around six camps at Boulogne in Northern France. He intended to use this invasion force to strike at England. They never invaded, but Napoleon's troops received careful and invaluable training for future military operations. The men at Boulogne formed the core for what Napoleon later called La Grande Armée. At the start, this French army had about 200,000 men organized into seven corps, which were large field units that contained 36 to 40 cannons each and were capable of independent action until other corps could come to the rescue. A single corps properly situated in a strong defensive position could survive at least a day without support, giving the Grande Armée countless strategic and tactical options on every campaign. On top of these forces, Napoleon created a cavalry reserve of 22,000 organized into two cuirassier divisions, four mounted dragoon divisions, one division of dismounted dragoons, and one of light cavalry, all supported by 24 artillery pieces. By 1805, the Grande Armée had grown to a force of 350,000 men, who were well equipped, well trained, and led by competent officers.
What country was the Armée d'Angleterre intended to strike at?
A: England
Problem: Please answer a question about the following article about House music:
In Britain, further experiments in the genre boosted its appeal. House and rave clubs such as Lakota and Cream emerged across Britain, hosting house and dance scene events. The 'chilling out' concept developed in Britain with ambient house albums such as The KLF's Chill Out and Analogue Bubblebath by Aphex Twin. The Godskitchen superclub brand also began in the midst of the early 90's rave scene. After initially hosting small nights in Cambridge and Northampton, the associated events scaled up in Milton Keynes, Birmingham and Leeds. A new indie dance scene also emerged in the 90's. In New York, bands such as Deee-Lite furthered house's international influence. Two distinctive tracks from this era were the Orb's "Little Fluffy Clouds" (with a distinctive vocal sample from Rickie Lee Jones) and the Happy Mondays' "Wrote for Luck" ("WFL") which was transformed into a dance hit by Vince Clarke.
who released the album analogue bubblebath?
A:
Aphex Twin
