Problem: Warsaw Pact:

On 25 February 1991, the Warsaw Pact was declared disbanded at a meeting of defense and foreign ministers from remaining Pact countries meeting in Hungary. On 1 July 1991, in Prague, the Czechoslovak President Václav Havel formally ended the 1955 Warsaw Treaty Organization of Friendship, Cooperation, and Mutual Assistance and so disestablished the Warsaw Treaty after 36 years of military alliance with the USSR. In fact, the treaty was de facto disbanded in December 1989 during the violent revolution in Romania, which toppled the communist government, without military intervention form other member states. The USSR disestablished itself in December 1991.

What pact was disbanded on 15 February 1991?

A: unanswerable


Problem: North Carolina was hard hit by the Great Depression, but the New Deal programs of Franklin D. Roosevelt for cotton and tobacco significantly helped the farmers. After World War II, the state's economy grew rapidly, highlighted by the growth of such cities as Charlotte, Raleigh, and Durham in the Piedmont. Raleigh, Durham, and Chapel Hill form the Research Triangle, a major area of universities and advanced scientific and technical research. In the 1990s, Charlotte became a major regional and national banking center. Tourism has also been a boon for the North Carolina economy as people flock to the Outer Banks coastal area and the Appalachian Mountains anchored by Asheville.
Who did the new deal programs benefit?

Answer: farmers


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Each year, nearly $200 million in hunters' federal excise taxes are distributed to state agencies to support wildlife management programs, the purchase of lands open to hunters, and hunter education and safety classes. Since 1934, the sale of Federal Duck Stamps, a required purchase for migratory waterfowl hunters over sixteen years old, has raised over $700 million to help purchase more than 5,200,000 acres (8,100 sq mi; 21,000 km2) of habitat for the National Wildlife Refuge System lands that support waterfowl and many other wildlife species and are often open to hunting. States also collect money from hunting licenses to assist with management of game animals, as designated by law. A key task of federal and state park rangers and game wardens is to enforce laws and regulations related to hunting, including species protection, hunting seasons, and hunting bans.
How much money is distributed to state agencies to support wildlife management programs each year?
A: $200 million


Context and question: Cytokinins are a class of plant hormones named for their control of cell division or cytokinesis. The natural cytokinin zeatin was discovered in corn, Zea mays, and is a derivative of the purine adenine. Zeatin is produced in roots and transported to shoots in the xylem where it promotes cell division, bud development, and the greening of chloroplasts. The gibberelins, such as Gibberelic acid are diterpenes synthesised from acetyl CoA via the mevalonate pathway. They are involved in the promotion of germination and dormancy-breaking in seeds, in regulation of plant height by controlling stem elongation and the control of flowering. Abscisic acid (ABA) occurs in all land plants except liverworts, and is synthesised from carotenoids in the chloroplasts and other plastids. It inhibits cell division, promotes seed maturation, and dormancy, and promotes stomatal closure. It was so named because it was originally thought to control abscission. Ethylene is a gaseous hormone that is produced in all higher plant tissues from methionine. It is now known to be the hormone that stimulates or regulates fruit ripening and abscission, and it, or the synthetic growth regulator ethephon which is rapidly metabolised to produce ethylene, are used on industrial scale to promote ripening of cotton, pineapples and other climacteric crops.
How is the height of a plant determined?
Answer: gibberelins


Question: In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. As these two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes.
Is there an answer to this question: What is the definition of bolus?

Answer: a small, round slurry mass


Question: Quoted at constant 2002 prices, GDP fell from £12 million in 1999-2000 to £11 million in 2005-06. Imports are mainly from the UK and South Africa and amounted to £6.4 million in 2004-05 (quoted on an FOB basis). Exports are much smaller, amounting to £0.2 million in 2004-05. Exports are mainly fish and coffee; Philatelic sales were £0.06 million in 2004-05. The limited number of visiting tourists spent about £0.4 million in 2004-05, representing a contribution to GDP of 3%.
Is there an answer to this question: Tourists spent how much in  2004-05?

Answer:
£0.4 million
