Problem: Mesozoic:

The lower (Triassic) boundary is set by the PermianTriassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the CretaceousTertiary (KT) extinction event (now more accurately called the CretaceousPaleogene (or KPg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatan Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the CretaceousPaleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.

How many terrestrial species died during the extinction?

A: 70%

Problem: Baird Television Ltd. made Britain's first television broadcast, on 30 September 1929 from its studio in Long Acre, London, via the BBC's London transmitter, using the electromechanical system pioneered by John Logie Baird. This system used a vertically-scanned image of 30 lines just enough resolution for a close-up of one person, and with a bandwidth low enough to use existing radio transmitters. Simultaneous transmission of sound and picture was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park. By late 1930, 30 minutes of morning programmes were broadcast Monday to Friday, and 30 minutes at midnight on Tuesdays and Fridays, after BBC radio went off the air. Baird broadcasts via the BBC continued until June 1932.
What was achieved on 30 March 1932?

The Greater Richmond area was named the third-best city for business by MarketWatch in September 2007, ranking behind only the Minneapolis and Denver areas and just above Boston. The area is home to six Fortune 500 companies: electric utility Dominion Resources; CarMax; Owens & Minor; Genworth Financial; MeadWestvaco; McKesson Medical-Surgical and Altria Group. However, only Dominion Resources and MeadWestvaco are headquartered within the city of Richmond; the others are located in the neighboring counties of Henrico and Hanover. In 2008, Altria moved its corporate HQ from New York City to Henrico County, adding another Fortune 500 corporation to Richmond's list. In February 2006, MeadWestvaco announced that they would move from Stamford, Connecticut, to Richmond in 2008 with the help of the Greater Richmond Partnership, a regional economic development organization that also helped locate Aditya Birla Minacs, Amazon.com, and Honeywell International, to the region.
Prior to moving to the Richmond area, where was Altria's headquarters located?
A: New York City

Context and question: President Richard Nixon declared current species conservation efforts to be inadequate and called on the 93rd United States Congress to pass comprehensive endangered species legislation. Congress responded with a completely rewritten law, the Endangered Species Act of 1973 which was signed by Nixon on December 28, 1973 (Pub.L. 93205). It was written by a team of lawyers and scientists, including the first appointed head of the Council on Environmental Quality (CEQ),an outgrowth of NEPA (The "National Environmental Policy Act of 1969") Dr. Russell E. Train. Dr. Train was assisted by a core group of staffers, including Dr. Earl Baysinger at EPA (currently Assistant Chief, Office of Endangered Species and International. Activities), Dick Gutting (U.S. Commerce Dept. lawyer, currently joined NOAA the previous year (1972), and Dr. Gerard A. "Jerry" Bertrand, a marine biologist (Ph.D, Oregon State University) by training, who had transferred from his post as the Scientific Adviser to the U.S Army Corps of Engineers, office of the Commandant of the Corp. to join the newly formed White House office. The staff, under Dr. Train's leadership, incorporated dozens of new principles and ideas into the landmark legislation; crafting a document that completely changed the direction of environmental conservation in the United States. Dr. Bertrand is credited with writing the most challenged section of the Act, the "takings" clause - Section 2.
What Congress called for the drafting of the Endangered Species Act of 1973?
Answer: the 93rd United States Congress

Question: The Song dynasty reestablished unity around 960. Under the Song, the prosperity of South China began to overtake that of North China. After the north was lost to the Jurchen Jin dynasty in 1127 following the Jingkang Incident, Hangzhou became the capital of the Southern Song under the name Lin'an. Renowned for its prosperity and beauty, it may have been the largest city in the world at the time. From then on, north Zhejiang and neighboring south Jiangsu have been synonymous with luxury and opulence in Chinese culture. The Mongol conquest and the establishment of the Yuan dynasty in 1279 ended Hangzhou's political clout, but its economy continued to prosper. Marco Polo visited the city, which he called "Kinsay" (after the Chinese Jingshi, meaning "Capital City") claiming it was "the finest and noblest city in the world".
Is there an answer to this question: What happened in 1126?

Answer: unanswerable
