Article: There are many notable contributors to the field of Chinese science throughout the ages. One of the best examples would be Shen Kuo (1031–1095), a polymath scientist and statesman who was the first to describe the magnetic-needle compass used for navigation, discovered the concept of true north, improved the design of the astronomical gnomon, armillary sphere, sight tube, and clepsydra, and described the use of drydocks to repair boats. After observing the natural process of the inundation of silt and the find of marine fossils in the Taihang Mountains (hundreds of miles from the Pacific Ocean), Shen Kuo devised a theory of land formation, or geomorphology. He also adopted a theory of gradual climate change in regions over time, after observing petrified bamboo found underground at Yan'an, Shaanxi province. If not for Shen Kuo's writing, the architectural works of Yu Hao would be little known, along with the inventor of movable type printing, Bi Sheng (990-1051). Shen's contemporary Su Song (1020–1101) was also a brilliant polymath, an astronomer who created a celestial atlas of star maps, wrote a pharmaceutical treatise with related subjects of botany, zoology, mineralogy, and metallurgy, and had erected a large astronomical clocktower in Kaifeng city in 1088. To operate the crowning armillary sphere, his clocktower featured an escapement mechanism and the world's oldest known use of an endless power-transmitting chain drive.

Question: What did silt and marine fossils teach Shen Kuo?
Ans: geomorphology


Here is a question about this article: The route carried the torch through six continents from March 2008 to May 2008 to August 2008. The planned route originally included a stop in Taipei between Ho Chi Minh City and Hong Kong, but there was disagreement in Beijing and Taipei over language used to describe whether it was an international or a domestic part of the route. While the Olympic committees of China and Chinese Taipei reached initial consensus on the approach, the government of the Republic of China in Taiwan intervened, stating that this placement could be interpreted as placing Taiwan on the same level as Hong Kong and Macau, an implication it objected to. The Beijing Organizing Committee attempted to continue negotiation, but further disputes arose over the flag or the anthem of the Republic of China along the 24 km torch route in Taiwan. By the midnight deadline for concluding the negotiation on September 21, 2007, Taiwan and China were unable to come to terms with the issue of the Torch Relay. In the end, both sides of the Taiwan Strait decided to eliminate the Taipei leg.
What is the answer to this question: How many continents did the torch visit?
****
So... six

Problem: Please answer a question about the following article about New Haven, Connecticut:
In April 2009, the United States Supreme Court agreed to hear a suit over reverse discrimination brought by 18 white firefighters against the city. The suit involved the 2003 promotion test for the New Haven Fire Department. After the tests were scored, no black firefighters scored high enough to qualify for consideration for promotion, so the city announced that no one would be promoted. In the subsequent Ricci v. DeStefano decision the court found 5-4 that New Haven's decision to ignore the test results violated Title VII of the Civil Rights Act of 1964. As a result, a district court subsequently ordered the city to promote 14 of the white firefighters.
What did the city do after the fail test scores for promotions?
A: no one would be promoted

Parisian examples of European architecture date back more than a millennium; including the Romanesque church of the Abbey of Saint-Germain-des-Prés (1014-1163); the early Gothic Architecture of the Basilica of Saint-Denis (1144), the Notre Dame Cathedral (1163-1345), the Flamboyant Gothic of Saint Chapelle (1239-1248), the Baroque churches of Saint-Paul-Saint-Louis (1627-1641) and Les Invalides (1670-1708). The 19th century produced the neoclassical church of La Madeleine (1808-1842); the Palais Garnier Opera House (1875); the neo-Byzantine Basilica of Sacré-Cœur (1875-1919), and the exuberant Belle Époque modernism of the Eiffel Tower (1889). Striking examples of 20th century architecture include the Centre Georges Pompidou by Richard Rogers and Renzo Piano (1977), and the Louvre Pyramid by I.M. Pei (1989). Contemporary architecture includes the Musée du Quai Branly by Jean Nouvel (2006) and the new contemporary art museum of the Louis Vuitton Foundation by Frank Gehry (2014).

The second decline was not as complete as the first. Thousands of people had learned to play the instrument. Even as the second wave of mandolin popularity declined in the early 20th century, new versions of the mandolin began to be used in new forms of music. Luthiers created the resonator mandolin, the flatback mandolin, the carved-top or arched-top mandolin, the mandolin-banjo and the electric mandolin. Musicians began playing it in Celtic, Bluegrass, Jazz and Rock-n-Roll styles — and Classical too.
Who created the rasonator mandolin?
Luthiers
