Input: Read this: Varmint hunting is an American phrase for the selective killing of non-game animals seen as pests. While not always an efficient form of pest control, varmint hunting achieves selective control of pests while providing recreation and is much less regulated. Varmint species are often responsible for detrimental effects on crops, livestock, landscaping, infrastructure, and pets. Some animals, such as wild rabbits or squirrels, may be utilised for fur or meat, but often no use is made of the carcass. Which species are varmints depends on the circumstance and area. Common varmints may include various rodents, coyotes, crows, foxes, feral cats, and feral hogs. Some animals once considered varmints are now protected, such as wolves. In the US state of Louisiana, a non-native rodent known as a nutria has become so destructive to the local ecosystem that the state has initiated a bounty program to help control the population.
Question: What detrimental effects are varmint species often responsible for visiting on?

Output: crops, livestock, landscaping, infrastructure, and pets.

Input: Read this: Centered on Post Oak Boulevard and Westheimer Road, the Uptown District boomed during the 1970s and early 1980s when a collection of mid-rise office buildings, hotels, and retail developments appeared along Interstate 610 west. Uptown became one of the most prominent instances of an edge city. The tallest building in Uptown is the 64-floor, 901-foot (275 m)-tall, Philip Johnson and John Burgee designed landmark Williams Tower (known as the Transco Tower until 1999). At the time of construction, it was believed to be the world's tallest skyscraper outside of a central business district. The new 20-story Skanska building and BBVA Compass Plaza are the newest office buildings built in Uptown after 30 years. The Uptown District is also home to buildings designed by noted architects I. M. Pei, Cesar Pelli, and Philip Johnson. In the late 1990s and early 2000s decade, there was a mini-boom of mid-rise and high-rise residential tower construction, with several over 30 stories tall. Since 2000 more than 30 high-rise buildings have gone up in Houston; all told, 72 high-rises tower over the city, which adds up to about 8,300 units. In 2002, Uptown had more than 23 million square feet (2,100,000 m) of office space with 16 million square feet (1,500,000 m) of Class A office space.
Question: How many square feet of office space did Texas have in 2003?

Output: unanswerable

Input: Read this: In 2003, additional UN sanctions were placed on Liberian timber exports, which had risen from US$5 million in 1997 to over US$100 million in 2002 and were believed to be funding rebels in Sierra Leone. These sanctions were lifted in 2006. Due in large part to foreign aid and investment inflow following the end of the war, Liberia maintains a large account deficit, which peaked at nearly 60% in 2008. Liberia gained observer status with the World Trade Organization in 2010 and is in the process of acquiring full member status.
Question: When was Liberia was granted observer status with the world trade organization>

Output: 2010

Input: Read this: In 2005, the Office of Fair Trading found fifty independent schools, including Eton, to have breached the Competition Act by "regularly and systematically" exchanging information about planned increases in school fees, which was collated and distributed among the schools by the bursar at Sevenoaks School. Following the investigation by the OFT, each school was required to pay around 70,000, totalling around 3.5 million, significantly less than the maximum possible fine. In addition, the schools together agreed to contribute another 3m to a new charitable educational fund. The incident raised concerns over whether the charitable status of independent schools such as Eton should be reconsidered, and perhaps revoked. However, Jean Scott, the head of the Independent Schools Council, said that independent schools had always been exempt from anti-cartel rules applied to business, were following a long-established procedure in sharing the information with each other, and that they were unaware of the change to the law (on which they had not been consulted). She wrote to John Vickers, the OFT director-general, saying, "They are not a group of businessmen meeting behind closed doors to fix the price of their products to the disadvantage of the consumer. They are schools that have quite openly continued to follow a long-established practice because they were unaware that the law had changed."
Question: In what year was a group of independent schools found guilty of price-sharing?

Output:
2005
