Question: Which did Jedlik do first: experimenting with electromagnetic coils or demonstating the stator, rotor and commutator? 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.

Context: The Greco-Egyptian scientist Claudius Ptolemy referred to the larger island as great Britain ( - megalis Brettanias) and to Ireland as little Britain ( - mikris Brettanias) in his work Almagest (147148 AD). In his later work, Geography (c. 150 AD), he gave these islands the names Alwion, Iwernia, and Mona (the Isle of Man), suggesting these may have been names of the individual islands not known to him at the time of writing Almagest. The name Albion appears to have fallen out of use sometime after the Roman conquest of Great Britain, after which Britain became the more commonplace name for the island called Great Britain.

Question: Which of the following is not something Presbyterians study: scriptures, generosity, or theological writings? Context: Presbyterians place great importance upon education and lifelong learning. Continuous study of the scriptures, theological writings, and understanding and interpretation of church doctrine are embodied in several statements of faith and catechisms formally adopted by various branches of the church, often referred to as "subordinate standards". It is generally considered that the point of such learning is to enable one to put one's faith into practice; some Presbyterians generally exhibit their faith in action as well as words, by generosity, hospitality, as well as proclaiming the gospel of Christ.

Context: The International Association for the Study of Pain advocates that the relief of pain should be recognized as a human right, that chronic pain should be considered a disease in its own right, and that pain medicine should have the full status of a specialty. It is a specialty only in China and Australia at this time. Elsewhere, pain medicine is a subspecialty under disciplines such as anesthesiology, physiatry, neurology, palliative medicine and psychiatry. In 2011, Human Rights Watch alerted that tens of millions of people worldwide are still denied access to inexpensive medications for severe pain.
