Problem: Extract the answer to the question from the following context. Question: When did math really start to blossom? Context: Three Han mathematical treatises still exist. These are the Book on Numbers and Computation, the Arithmetical Classic of the Gnomon and the Circular Paths of Heaven and the Nine Chapters on the Mathematical Art. Han-era mathematical achievements include solving problems with right-angle triangles, square roots, cube roots, and matrix methods, finding more accurate approximations for pi, providing mathematical proof of the Pythagorean theorem, use of the decimal fraction, Gaussian elimination to solve linear equations, and continued fractions to find the roots of equations.

A: Han-era

Problem: Given the question: Extract the answer to the question from the following context. Question: What is a different word for "parishes"? Context: In May 1845, the Baptist congregations in the United States split over slavery and missions. The Home Mission Society prevented slaveholders from being appointed as missionaries. The split created the Southern Baptist Convention, while the northern congregations formed their own umbrella organization now called the American Baptist Churches USA (ABC-USA). The Methodist Episcopal Church, South had recently separated over the issue of slavery, and southern Presbyterians would do so shortly thereafter.

input question: Extract the answer to the question from the following context. Question: In which year were the revised standards for mpeg issued? Context: Further work on MPEG audio was finalized in 1994 as part of the second suite of MPEG standards, MPEG-2, more formally known as international standard ISO/IEC 13818-3 (a.k.a. MPEG-2 Part 3 or backwards compatible MPEG-2 Audio or MPEG-2 Audio BC), originally published in 1995. MPEG-2 Part 3 (ISO/IEC 13818-3) defined additional bit rates and sample rates for MPEG-1 Audio Layer I, II and III. The new sampling rates are exactly half that of those originally defined in MPEG-1 Audio. This reduction in sampling rate serves to cut the available frequency fidelity in half while likewise cutting the bitrate by 50%. MPEG-2 Part 3 also enhanced MPEG-1's audio by allowing the coding of audio programs with more than two channels, up to 5.1 multichannel.???
output answer: 1995

Extract the answer to the question from the following context. Question: What is another word for sending goods to other places? Context: Larger SAMs may be deployed in fixed launchers, but can be towed/re-deployed at will. The SAMs launched by individuals are known in the United States as the Man-Portable Air Defence Systems (MANPADS). MANPADS of the former Soviet Union have been exported around the World, and can be found in use by many armed forces. Targets for non-ManPAD SAMs will usually be acquired by air-search radar, then tracked before/while a SAM is "locked-on" and then fired. Potential targets, if they are military aircraft, will be identified as friend or foe before being engaged. The developments in the latest and relatively cheap short-range missiles have begun to replace autocannons in this role.

Answer: exported

Q: Extract the answer to the question from the following context. Question: Where did Nakajima work second, NHK or Sony? 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: Sony

[Q]: Extract the answer to the question from the following context. Question: What would lead you to guess the majority of this city is religious? Context: Boston has been a noted religious center from its earliest days. The Roman Catholic Archdiocese of Boston serves nearly 300 parishes and is based in the Cathedral of the Holy Cross (1875) in the South End, while the Episcopal Diocese of Massachusetts, with the Cathedral Church of St. Paul (1819) as its episcopal seat, serves just under 200 congregations. Unitarian Universalism has its headquarters on Beacon Hill. The Christian Scientists are headquartered in Back Bay at the Mother Church (1894). The oldest church in Boston is First Church in Boston, founded in 1630. King's Chapel, the city's first Anglican church, was founded in 1686 and converted to Unitarianism in 1785. Other churches include Christ Church (better known as Old North Church, 1723), the oldest church building in the city, Trinity Church (1733), Park Street Church (1809), Old South Church (1874), Jubilee Christian Church and Basilica and Shrine of Our Lady of Perpetual Help on Mission Hill (1878).
