Problem: Antibiotics:

The emergence of resistance of bacteria to antibiotics is a common phenomenon. Emergence of resistance often reflects evolutionary processes that take place during antibiotic therapy. The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. For example, antibacterial selection for strains having previously acquired antibacterial-resistance genes was demonstrated in 1943 by the Luria–Delbrück experiment. Antibiotics such as penicillin and erythromycin, which used to have a high efficacy against many bacterial species and strains, have become less effective, due to the increased resistance of many bacterial strains.

Which two antibiotics that have high efficacy are much less useful now?
---
A: penicillin and erythromycin


Problem: Major League Baseball is especially well known for red teams. The Cincinnati Red Stockings are the oldest professional baseball team, dating back to 1869. The franchise soon relocated to Boston and is now the Atlanta Braves, but its name survives as the origin for both the Cincinnati Reds and Boston Red Sox. During the 1950s when red was strongly associated with communism, the modern Cincinnati team was known as the "Redlegs" and the term was used on baseball cards. After the red scare faded, the team was known as the "Reds" again. The Los Angeles Angels of Anaheim are also known for their color red, as are the St. Louis Cardinals, Arizona Diamondbacks, and the Philadelphia Phillies.
When did the Cincinnati Red Stockings come to be?

Answer: 1869


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Dorgon's controversial July 1645 edict (the "haircutting order") forced adult Han Chinese men to shave the front of their heads and comb the remaining hair into the queue hairstyle which was worn by Manchu men, on pain of death. The popular description of the order was: "To keep the hair, you lose the head; To keep your head, you cut the hair." To the Manchus, this policy was a test of loyalty and an aid in distinguishing friend from foe. For the Han Chinese, however, it was a humiliating reminder of Qing authority that challenged traditional Confucian values. The Classic of Filial Piety (Xiaojing) held that "a person's body and hair, being gifts from one's parents, are not to be damaged." Under the Ming dynasty, adult men did not cut their hair but instead wore it in the form of a top-knot. The order triggered strong resistance to Qing rule in Jiangnan and massive killing of ethnic Han Chinese. It was Han Chinese defectors who carried out massacres against people refusing to wear the queue.. Li Chengdong, a Han Chinese general who had served the Ming but surrendered to the Qing, ordered his Han troops to carry out three separate massacres in the city of Jiading within a month, resulting in tens of thousands of deaths. At the end of the third massacre, there was hardly any living person left in this city. Jiangyin also held out against about 10,000 Han Chinese Qing troops for 83 days. When the city wall was finally breached on 9 October 1645, the Han Chinese Qing army led by the Han Chinese Ming defector Liu Liangzuo (劉良佐), who had been ordered to "fill the city with corpses before you sheathe your swords," massacred the entire population, killing between 74,000 and 100,000 people. The queue was the only aspect of Manchu culture which the Qing forced on the common Han population. The Qing required people serving as officials to wear Manchu clothing, but allowed non-official Han civilians to continue wearing Hanfu (Han clothing).
What was the peoples description of the haircutting order?
A: "To keep the hair, you lose the head; To keep your head, you cut the hair."


Context and question: The use of the term Länder (Lands) dates back to the Weimar Constitution of 1919. Before this time, the constituent states of the German Empire were called Staaten (States). Today, it is very common to use the term Bundesland (Federal Land). However, this term is not used officially, neither by the constitution of 1919 nor by the Basic Law (Constitution) of 1949. Three Länder call themselves Freistaaten (Free States, which is the old-fashioned German expression for Republic), Bavaria (since 1919), Saxony (originally since 1919 and again since 1990), and Thuringia (since 1994). There is little continuity between the current states and their predecessors of the Weimar Republic with the exception of the three free states, and the two city-states of Hamburg and Bremen.
What does Bavaria refer to itself as?
Answer: Freistaaten


Question: US troops participated in a UN peacekeeping mission in Somalia beginning in 1992. By 1993 the US troops were augmented with Rangers and special forces with the aim of capturing warlord Mohamed Farrah Aidid, whose forces had massacred peacekeepers from Pakistan. During a raid in downtown Mogadishu, US troops became trapped overnight by a general uprising in the Battle of Mogadishu. Eighteen American soldiers were killed, and a US television crew filmed graphic images of the body of one soldier being dragged through the streets by an angry mob. Somali guerrillas paid a staggering toll at an estimated 1,000–5,000 total casualties during the conflict. After much public disapproval, American forces were quickly withdrawn by President Bill Clinton. The incident profoundly affected US thinking about peacekeeping and intervention. The book Black Hawk Down was written about the battle, and was the basis for the later movie of the same name.
Is there an answer to this question:  How many UK soldiers were killed in the battle of Mogadishu?

Answer: unanswerable


QUES: The first attempt to establish a proper governing body and adopted the current set of Rugby rules was the Foot Ball Association of Canada, organized on March 24, 1873 followed by the Canadian Rugby Football Union (CRFU) founded June 12, 1880, which included teams from Ontario and Quebec. Later both the Ontario and Quebec Rugby Football Union (ORFU and QRFU) were formed (January 1883), and then the Interprovincial (1907) and Western Interprovincial Football Union (1936) (IRFU and WIFU). The CRFU reorganized into an umbrella organization forming the Canadian Rugby Union (CRU) in 1891. The original forerunners to the current Canadian Football League, was established in 1956 when the IRFU and WIFU formed an umbrella organization, The Canadian Football Council (CFC). And then in 1958 the CFC left The CRFU to become The CFL.
