Problem: Extract the answer to the question from the following context. Question: Which happened first, Heitaro Nakajima developed an early digital audio recorder or became general manager of Sony's audio department? Context: Heitaro Nakajima, who developed an early digital audio recorder within Japan's national public broadcasting organization NHK in 1970, became general manager of Sony's audio department in 1971. His team developed a digital PCM adaptor audio tape recorder using a Betamax video recorder in 1973. After this, in 1974 the leap to storing digital audio on an optical disc was easily made. Sony first publicly demonstrated an optical digital audio disc in September 1976. A year later, in September 1977, Sony showed the press a 30 cm disc that could play 60 minutes of digital audio (44,100 Hz sampling rate and 16-bit resolution) using MFM modulation. In September 1978, the company demonstrated an optical digital audio disc with a 150-minute playing time, 44,056 Hz sampling rate, 16-bit linear resolution, and cross-interleaved error correction codespecifications similar to those later settled upon for the standard Compact Disc format in 1980. Technical details of Sony's digital audio disc were presented during the 62nd AES Convention, held on 1316 March 1979, in Brussels. Sony's AES technical paper was published on 1 March 1979. A week later, on 8 March, Philips publicly demonstrated a prototype of an optical digital audio disc at a press conference called "Philips Introduce Compact Disc" in Eindhoven, Netherlands.

A: developed an early digital audio recorder

Problem: Given the question: Extract the answer to the question from the following context. Question: How are power ratios measured? Context: As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.

The answer is:
SWR

input question: Extract the answer to the question from the following context. Question: Which of the following is not a type of food, meat, genetics or eggs? Context: "Poultry" is a term used for any kind of domesticated bird, captive-raised for its utility, and traditionally the word has been used to refer to wildfowl (Galliformes) and waterfowl (Anseriformes). "Poultry" can be defined as domestic fowls, including chickens, turkeys, geese and ducks, raised for the production of meat or eggs and the word is also used for the flesh of these birds used as food. The Encyclopdia Britannica lists the same bird groups but also includes guinea fowl and squabs (young pigeons). In R. D. Crawford's Poultry breeding and genetics, squabs are omitted but Japanese quail and common pheasant are added to the list, the latter frequently being bred in captivity and released into the wild. In his 1848 classic book on poultry, Ornamental and Domestic Poultry: Their History, and Management, Edmund Dixon included chapters on the peafowl, guinea fowl, mute swan, turkey, various types of geese, the muscovy duck, other ducks and all types of chickens including bantams. In colloquial speech, the term "fowl" is often used near-synonymously with "domesticated chicken" (Gallus gallus), or with "poultry" or even just "bird", and many languages do not distinguish between "poultry" and "fowl". Both words are also used for the flesh of these birds. Poultry can be distinguished from "game", defined as wild birds or mammals hunted for food or sport, a word also used to describe the flesh of these when eaten.???

Extract the answer to the question from the following context. Question: What group was Constantius against with his renewed policies? Context: Constantius, renewing his previous policies favoring the Arians, banished Athanasius from Alexandria once again. This was followed, in 356, by an attempt to arrest Athanasius during a vigil service. Athanasius fled to Upper Egypt, where he stayed in several monasteries and other houses. During this period, Athanasius completed his work Four Orations against the Arians and defended his own recent conduct in the Apology to Constantius and Apology for His Flight. Constantius's persistence in his opposition to Athanasius, combined with reports Athanasius received about the persecution of non-Arians by the new Arian bishop George of Laodicea, prompted Athanasius to write his more emotional History of the Arians, in which he described Constantius as a precursor of the Antichrist.

Answer: non-Arians

Q: Extract the answer to the question from the following context. Question: How was Christian Doctrine unable to be enforced? Context: At the time, there were many varying opinions about Christian doctrine, and no centralized way of enforcing orthodoxy. Constantine called all the Christian bishops throughout the Roman Empire to a meeting, and some 318 bishops (very few from the Western Empire) attended the First Council of Nicaea. The purpose of this meeting was to define Christian orthodoxy and clearly differentiate it from Christian heresies. The meeting reached consensus on the Nicene Creed and other statements. Later, Philostorgius criticized Christians who offered sacrifice at statues of the divus Constantine. Constantine nevertheless took great pains to assuage traditionalist and Christian anxieties.
A: centralized

[Q]: Extract the answer to the question from the following context. Question: How does one prevent a wrestling bear from mauling an audience member who has chosen to fight it? Context: Though they have not had the level of exposure as other wrestlers, bears have long been a part of professional wrestling. Usually declawed and muzzled, they often wrestled shoot matches against audience members, offered a cash reward if they could pin the bear. They also wrestled professionals in worked, often battle royal or handicap, matches (usually booked so the bear won). Though they have wrestled around the world and continue to do so, wrestling bears enjoyed their greatest popularity in the Southern United States, during the 1960s and 1970s. The practice of bear wrestling has met strong opposition from animal rights activists in recent decades, contributing to its lack of mainstream acceptance. As of 2006, it is banned in 20 U.S. states. Perhaps the most famous wrestling bears are Ginger, Victor, Hercules and Terrible Ted.
