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 is the purpose of the BeiDou-1 system using stallites in geostationary orbit?
A: the system does not require a large constellation of satellites
Problem: Please answer a question about the following article about Myanmar:
The government has also relaxed reporting laws, but these remain highly restrictive. In September 2011, several banned websites, including YouTube, Democratic Voice of Burma and Voice of America, were unblocked. A 2011 report by the Hauser Center for Nonprofit Organizations found that, while contact with the Myanmar government was constrained by donor restrictions, international humanitarian non-governmental organisations (NGOs) see opportunities for effective advocacy with government officials, especially at the local level. At the same time, international NGOs are mindful of the ethical quandary of how to work with the government without bolstering or appeasing it.
Has the government of Myanmar made life any easier for it's inhabitants ?
A: has also relaxed reporting laws, but these remain highly restrictive.
Problem: Please answer a question about the following article about Age of Enlightenment:
The first scientific and literary journals were established during the Enlightenment. The first journal, the Parisian Journal des Sçavans, appeared in 1665. However, it was not until 1682 that periodicals began to be more widely produced. French and Latin were the dominant languages of publication, but there was also a steady demand for material in German and Dutch. There was generally low demand for English publications on the Continent, which was echoed by England's similar lack of desire for French works. Languages commanding less of an international market – such as Danish, Spanish and Portuguese – found journal success more difficult, and more often than not, a more international language was used instead. French slowly took over Latin's status as the lingua franca of learned circles. This in turn gave precedence to the publishing industry in Holland, where the vast majority of these French language periodicals were produced.
In what year did the first scientific and literary journal appear?
A: 1665
Problem: Please answer a question about the following article about Dell:
In the early 1990s, Dell sold its products through Best Buy, Costco and Sam's Club stores in the United States. Dell stopped this practice in 1994, citing low profit-margins on the business, exclusively distributing through a direct-sales model for the next decade. In 2003, Dell briefly sold products in Sears stores in the U.S. In 2007, Dell started shipping its products to major retailers in the U.S. once again, starting with Sam's Club and Wal-Mart. Staples, the largest office-supply retailer in the U.S., and Best Buy, the largest electronics retailer in the U.S., became Dell retail partners later that same year.
What store did Dell sell electronics at in 2003?
A:
Sears
