Problem: San Diego:

Due to the ratio of U.S. and Mexican-licensed stations, San Diego is the largest media market in the United States that is legally unable to support a television station duopoly between two full-power stations under FCC regulations, which disallow duopolies in metropolitan areas with fewer than nine full-power television stations and require that there must be eight unique station owners that remain once a duopoly is formed (there are only seven full-power stations on the California side of the San Diego-Tijuana market).[citation needed] Though the E. W. Scripps Company owns KGTV and KZSD-LP, they are not considered a duopoly under the FCC's legal definition as common ownership between full-power and low-power television stations in the same market is permitted regardless to the number of stations licensed to the area. As a whole, the Mexico side of the San Diego-Tijuana market has two duopolies and one triopoly (Entravision Communications owns both XHAS-TV and XHDTV-TV, Azteca owns XHJK-TV and XHTIT-TV, and Grupo Televisa owns XHUAA-TV and XHWT-TV along with being the license holder for XETV-TV, which is run by California-based subsidiary Bay City Television).

What company disowns XHDTV-TV and XHAS-TV?

Problem: In 1368, a Han Chinese revolt known as the Red Turban Rebellion toppled the Mongol Yuan dynasty in China. Zhu Yuanzhang then established the Ming dynasty, ruling as the Hongwu Emperor (r. 13681398). It is not clear how much the early Ming court understood the civil war going on in Tibet between rival religious sects, but the first emperor was anxious to avoid the same trouble that Tibet had caused for the Tang dynasty. Instead of recognizing the Phagmodru ruler, the Hongwu Emperor sided with the Karmapa of the nearer Kham region and southeastern Tibet, sending envoys out in the winter of 13721373 to ask the Yuan officeholders to renew their titles for the new Ming court.
Who caused the Yuan dynasty to fall?

Answer: the Red Turban Rebellion

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Drug discovery and development is very expensive; of all compounds investigated for use in humans only a small fraction are eventually approved in most nations by government appointed medical institutions or boards, who have to approve new drugs before they can be marketed in those countries. In 2010 18 NMEs (New Molecular Entities) were approved and three biologics by the FDA, or 21 in total, which is down from 26 in 2009 and 24 in 2008. On the other hand, there were only 18 approvals in total in 2007 and 22 back in 2006. Since 2001, the Center for Drug Evaluation and Research has averaged 22.9 approvals a year. This approval comes only after heavy investment in pre-clinical development and clinical trials, as well as a commitment to ongoing safety monitoring. Drugs which fail part-way through this process often incur large costs, while generating no revenue in return. If the cost of these failed drugs is taken into account, the cost of developing a successful new drug (new chemical entity, or NCE), has been estimated at about 1.3 billion USD(not including marketing expenses). Professors Light and Lexchin reported in 2012, however, that the rate of approval for new drugs has been a relatively stable average rate of 15 to 25 for decades.
What does NMEs stand for?
A: New Molecular Entities

Context and question: Agriculture and forestry have declined in importance over the decades. Nevertheless, they are more important than in the most other areas of Germany, especially within rural regions. 54% of Thuringia's territory is in agricultural use. The fertile basins such as the large Thuringian Basin or the smaller Goldene Aue, Orlasenke and Osterland are in intensive use for growing cereals, vegetables, fruits and energy crops. Important products are apples, strawberries, cherries and plums in the fruit sector, cabbage, potatoes, cauliflower, tomatoes (grown in greenhouses), onions, cucumbers and asparagus in the vegetable sector, as well as maize, rapeseed, wheat, barley and sugar beets in the crop sector.
How much of Thuringia's territory is in agricultural use?
Answer: 54%

Other notable places include Elizabeth Fort, the Cork Opera House, Christ Church on South Main Street (now the Triskel Arts Centre and original site of early Hiberno-Norse church), St Mary's Dominican Church on Popes Quay and Fitzgerald's Park to the west of the city, which contains the Cork Public Museum. Other popular tourist attractions include the grounds of University College Cork, through which the River Lee flows, the Women's Gaol at Sundays Well (now a heritage centre) and the English Market. This covered market traces its origins back to 1610, and the present building dates from 1786.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What market has a building from the 17th century?
Ah, so..
