Input: Article: The climate in San Diego, like most of Southern California, often varies significantly over short geographical distances resulting in microclimates. In San Diego, this is mostly because of the city's topography (the Bay, and the numerous hills, mountains, and canyons). Frequently, particularly during the "May gray/June gloom" period, a thick "marine layer" cloud cover will keep the air cool and damp within a few miles of the coast, but will yield to bright cloudless sunshine approximately 510 miles (8.016.1 km) inland. Sometimes the June gloom can last into July, causing cloudy skies over most of San Diego for the entire day. Even in the absence of June gloom, inland areas tend to experience much more significant temperature variations than coastal areas, where the ocean serves as a moderating influence. Thus, for example, downtown San Diego averages January lows of 50 F (10 C) and August highs of 78 F (26 C). The city of El Cajon, just 10 miles (16 km) inland from downtown San Diego, averages January lows of 42 F (6 C) and August highs of 88 F (31 C).

Now answer this question: What is the average January low temperature in downtown San Diego?

Output: 50 F (10 C)

Input: Article: The official English name of the system is BeiDou Navigation Satellite System. It is named after the Big Dipper constellation, which is known in Chinese as Beidou. The name literally means "Northern Dipper", the name given by ancient Chinese astronomers to the seven brightest stars of the Ursa Major constellation. Historically, this set of stars was used in navigation to locate the North Star Polaris. As such, the name BeiDou also serves as a metaphor for the purpose of the satellite navigation system.

Now answer this question: What does Beidou translate as?

Output: Northern Dipper

Input: Article: Due to industrial restructuring and loss of jobs in the auto industry, Detroit lost considerable population from the late 20th century to present. Between 2000 and 2010 the city's population fell by 25 percent, changing its ranking from the nation's 10th-largest city to 18th. In 2010, the city had a population of 713,777, more than a 60 percent drop from a peak population of over 1.8 million at the 1950 census. This resulted from suburbanization, industrial restructuring, and the decline of Detroit's auto industry. Following the shift of population and jobs to its suburbs or other states or nations, the city has focused on becoming the metropolitan region's employment and economic center. Downtown Detroit has held an increased role as an entertainment destination in the 21st century, with the restoration of several historic theatres, several new sports stadiums, and a riverfront revitalization project. More recently, the population of Downtown Detroit, Midtown Detroit, and a handful of other neighborhoods has increased. Many other neighborhoods remain distressed, with extensive abandonment of properties.

Now answer this question: By how much has Detroit's population fallen this century?

Output:
25
