Question: Extract the answer to the question from the following context. Question: Where did the development of electric motors begin? Context: In 1827, Hungarian physicist Anyos Jedlik started experimenting with electromagnetic coils. After Jedlik solved the technical problems of the continuous rotation with the invention of the commutator, he called his early devices "electromagnetic self-rotors". Although they were used only for instructional purposes, in 1828 Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator, rotor and commutator. The device employed no permanent magnets, as the magnetic fields of both the stationary and revolving components were produced solely by the currents flowing through their windings.
Answer: electromagnetic coils

Question: Extract the answer to the question from the following context. Question: What is the difference between Republicans and Democrats concerning the election of speaker once they aren't the minority in the house anymore? Context: Second, Democrats have always elevated their minority floor leader to the speakership upon reclaiming majority status. Republicans have not always followed this leadership succession pattern. In 1919, for instance, Republicans bypassed James R. Mann, R-IL, who had been minority leader for eight years, and elected Frederick Gillett, R-MA, to be Speaker. Mann "had angered many Republicans by objecting to their private bills on the floor;" also he was a protege of autocratic Speaker Joseph Cannon, R-IL (19031911), and many Members "suspected that he would try to re-centralize power in his hands if elected Speaker." More recently, although Robert H. Michel was the Minority Leader in 1994 when the Republicans regained control of the House in the 1994 midterm elections, he had already announced his retirement and had little or no involvement in the campaign, including the Contract with America which was unveiled six weeks before voting day.
Answer: Democrats have always elevated their minority floor leader to the speakership upon reclaiming majority status

Question: Extract the answer to the question from the following context. Question: WHat are muslims instructed to do with evidence? Context: The astrophysicist Nidhal Guessoum while being highly critical of pseudo-scientific claims made about the Quran, has highlighted the encouragement for sciences that the Quran provides by developing "the concept of knowledge.". He writes: "The Qur'an draws attention to the danger of conjecturing without evidence (And follow not that of which you have not the (certain) knowledge of... 17:36) and in several different verses asks Muslims to require proofs (Say: Bring your proof if you are truthful 2:111), both in matters of theological belief and in natural science." Guessoum cites Ghaleb Hasan on the definition of "proof" according the Quran being "clear and strong... convincing evidence or argument." Also, such a proof cannot rely on an argument from authority, citing verse 5:104. Lastly, both assertions and rejections require a proof, according to verse 4:174. Ismail al-Faruqi and Taha Jabir Alalwani are of the view that any reawakening of the Muslim civilization must start with the Quran; however, the biggest obstacle on this route is the "centuries old heritage of tafseer (exegesis) and other classical disciplines" which inhibit a "universal, epidemiological and systematic conception" of the Quran's message. The philosopher Muhammad Iqbal, considered the Quran's methodology and epistemology to be empirical and rational.
Answer:
Bring your proof if you are truthful 2:111
