Please answer this: Extract the answer to the question from the following context. Question: How many phases of a hysteresis synchronous motor do not use a phase-shifting capacitor? Context: Finally, hysteresis synchronous motors typically are (essentially) two-phase motors with a phase-shifting capacitor for one phase. They start like induction motors, but when slip rate decreases sufficiently, the rotor (a smooth cylinder) becomes temporarily magnetized. Its distributed poles make it act like a PMSM. The rotor material, like that of a common nail, will stay magnetized, but can also be demagnetized with little difficulty. Once running, the rotor poles stay in place; they do not drift.

Problem: Extract the answer to the question from the following context. Question: Who warns members to "avoid independent thinking"? Context: Doctrines of Jehovah's Witnesses are established by the Governing Body. The religion does not tolerate dissent over doctrines and practices; members who openly disagree with the religion's teachings are expelled and shunned. Witness publications strongly discourage followers from questioning doctrine and counsel received from the Governing Body, reasoning that it is to be trusted as part of "God's organization". It also warns members to "avoid independent thinking", claiming such thinking "was introduced by Satan the Devil" and would "cause division". Those who openly disagree with official teachings are condemned as "apostates" who are "mentally diseased".

A: the Governing Body
Problem: Given the question: Extract the answer to the question from the following context. Question: Which of the following is not a rock band: Band of Skulls, The Delays, or Craig David? Context: The city is home or birthplace to a number of contemporary musicians such as R'n'B singer Craig David, Coldplay drummer Will Champion, former Holloways singer Rob Skipper as well as 1980s popstar Howard Jones. Several rock bands were formed in Southampton, including Band of Skulls, The Delays, Bury Tomorrow, Heart in Hand, Thomas Tantrum (disbanded in 2011) and Kids Can't Fly (disbanded in 2014). James Zabiela, a highly regarded and recognised name in dance music, is also from Southampton.

input question: Extract the answer to the question from the following context. Question: What don't I need to avoid if I want to see a Barbier 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 -hydroxycarboxylic esters RR'COHCOOR, the Reformatskii reaction which converts -halo-esters and aldehydes to -hydroxy-esters, the SimmonsSmith 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:???

Q: Extract the answer to the question from the following context. Question: How has London grown? Context: Within London, both the City of London and the City of Westminster have city status and both the City of London and the remainder of Greater London are counties for the purposes of lieutenancies. The area of Greater London has incorporated areas that were once part of the historic counties of Middlesex, Kent, Surrey, Essex and Hertfordshire. London's status as the capital of England, and later the United Kingdom, has never been granted or confirmed officiallyby statute or in written form.[note 6]
