Problem: Given the question: Extract the answer to the question from the following context. Question: Who fought in the first rebellion? Context: A struggle for succession in the mid-twelfth century gave the Fujiwara an opportunity to regain their former power. Fujiwara no Yorinaga sided with the retired emperor in a violent battle in 1156 against the heir apparent, who was supported by the Taira and Minamoto (Hōgen Rebellion). In the end, the Fujiwara were destroyed, the old system of government supplanted, and the insei system left powerless as bushi took control of court affairs, marking a turning point in Japanese history. In 1159, the Taira and Minamoto clashed (Heiji Rebellion), and a twenty-year period of Taira ascendancy began.

input question: Extract the answer to the question from the following context. Question: What disadvantages does the the Barbier reaction have compared to the Grignard reaction? Context: There are many important organozinc compounds. Organozinc chemistry is the science of organozinc compounds describing their physical properties, synthesis and reactions. Among important applications is the Frankland-Duppa Reaction in which an oxalate ester(ROCOCOOR) reacts with an alkyl halide R'X, zinc and hydrochloric acid to the α-hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts α-halo-esters and aldehydes to β-hydroxy-esters, the Simmons–Smith reaction in which the carbenoid (iodomethyl)zinc iodide reacts with alkene(or alkyne) and converts them to cyclopropane, the Addition reaction of organozinc compounds to carbonyl compounds. The Barbier reaction (1899) is the zinc equivalent of the magnesium Grignard reaction and is better of the two. In presence of just about any water the formation of the organomagnesium halide will fail, whereas the Barbier reaction can even take place in water. On the downside organozincs are much less nucleophilic than Grignards, are expensive and difficult to handle. Commercially available diorganozinc compounds are dimethylzinc, diethylzinc and diphenylzinc. In one study the active organozinc compound is obtained from much cheaper organobromine precursors:???
output answer: much less nucleophilic than Grignards, are expensive and difficult to handle


Extract the answer to the question from the following context. Question: What is the title of people Kant drew concepts from? Context: The 2nd edition (1787) contained a Refutation of Idealism to distinguish his transcendental idealism from Descartes's Sceptical Idealism and Berkeley's anti-realist strain of Subjective Idealism. The section Paralogisms of Pure Reason is an implicit critique of Descartes' idealism. Kant says that it is not possible to infer the 'I' as an object (Descartes' cogito ergo sum) purely from "the spontaneity of thought". Kant focused on ideas drawn from British philosophers such as Locke, Berkeley and Hume but distinguished his transcendental or critical idealism from previous varieties;

Q: Extract the answer to the question from the following context. Question: Despite what the classrooms look the same? Context: The primary responsibility for a boy's studies lies with his House Master, but he is assisted by an additional director of studies, known as a tutor. Classes, colloquially known as "divs" (divisions), are organised on a School basis; the classrooms are separate from the houses. New school buildings have appeared for teaching purposes every decade or so since New Schools, designed by Henry Woodyer and built 1861-3. Despite the introduction of modern technology, the external appearance and locations of many of the classrooms have remained unchanged for a long time.
A: the introduction of modern technology


Question: Extract the answer to the question from the following context. Question: Who is most likely to buy records? Context: In spite of their flaws, such as the lack of portability, records still have enthusiastic supporters. Vinyl records continue to be manufactured and sold today, especially by independent rock bands and labels, although record sales are considered to be a niche market composed of audiophiles, collectors, and DJs. Old records and out-of-print recordings in particular are in much demand by collectors the world over. (See Record collecting.) Many popular new albums are given releases on vinyl records and older albums are also given reissues, sometimes on audiophile-grade vinyl.
Answer: audiophiles, collectors, and DJs
