Article: Videoconferencing is a highly useful technology for real-time telemedicine and telenursing applications, such as diagnosis, consulting, transmission of medical images, etc... With videoconferencing, patients may contact nurses and physicians in emergency or routine situations; physicians and other paramedical professionals can discuss cases across large distances. Rural areas can use this technology for diagnostic purposes, thus saving lives and making more efficient use of health care money. For example, a rural medical center in Ohio, United States, used videoconferencing to successfully cut the number of transfers of sick infants to a hospital 70 miles (110 km) away. This had previously cost nearly $10,000 per transfer.

Question: What areas benefit especially from videoconferencing? 
Ans: Rural


Here is a question about this article: During the Early Modern period (approximately late 15th century to 1800), the universities of Europe would see a tremendous amount of growth, productivity and innovative research. At the end of the Middle Ages, about 400 years after the first university was founded, there were twenty-nine universities spread throughout Europe. In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) – this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time. It should be noted that the identification of a university was not necessarily obvious during the Early Modern period, as the term is applied to a burgeoning number of institutions. In fact, the term "university" was not always used to designate a higher education institution. In Mediterranean countries, the term studium generale was still often used, while "Academy" was common in Northern European countries.
What is the answer to this question: What was the time span of the Early Modern period?
****
So... late 15th century to 1800

One mustn't overlook the doctrines of Galen: In use from his life in the 1st century AD until the 17th century, it was heresy to disagree with him for 1500 years. Galen was physician to gladiators in Pergamon, and in Rome, physician to Marcus Aurelius and the three emperors who succeeded him. Most of Galen's teachings were gathered and enhanced in the late 11th century by Benedictine monks at the School of Salerno in Regimen sanitatis Salernitanum, which still had users in the 17th century. Galen believed in the bodily humours of Hippocrates, and he taught that pneuma is the source of life. Four elements (earth, air, fire and water) combine into "complexion", which combines into states (the four temperaments: sanguine, phlegmatic, choleric, and melancholic). The states are made up of pairs of attributes (hot and moist, cold and moist, hot and dry, and cold and dry), which are made of four humours: blood, phlegm, green (or yellow) bile, and black bile (the bodily form of the elements). Galen thought that for a person to have gout, kidney stones, or arthritis was scandalous, which Gratzer likens to Samuel Butler's Erehwon (1872) where sickness is a crime.
What did Galen believe that pneuma was?
****
The answer: the source of life


Problem: Please answer a question about the following article about Electric motor:
Doubly fed electric motors have two independent multiphase winding sets, which contribute active (i.e., working) power to the energy conversion process, with at least one of the winding sets electronically controlled for variable speed operation. Two independent multiphase winding sets (i.e., dual armature) are the maximum provided in a single package without topology duplication. Doubly-fed electric motors are machines with an effective constant torque speed range that is twice synchronous speed for a given frequency of excitation. This is twice the constant torque speed range as singly-fed electric machines, which have only one active winding set.
What is one of the independent multiphase winding sets configured for?
A: variable speed operation

An early non-Christian reference to the crucifixion of Jesus is likely to be Mara Bar-Serapion's letter to his son, written sometime after AD 73 but before the 3rd century AD. The letter includes no Christian themes and the author is presumed to be a pagan. The letter refers to the retributions that followed the unjust treatment of three wise men: Socrates, Pythagoras, and "the wise king" of the Jews. Some scholars see little doubt that the reference to the execution of the "king of the Jews" is about the crucifixion of Jesus, while others place less value in the letter, given the possible ambiguity in the reference.

Does everyone agree with the content of the letter?
Answer: others place less value in the letter


Cuba, like many Spanish territories, wanted to break free from Spain. A pro-independence movement in Cuba was supported by the U.S., and Cuban guerrilla leaders wanted annexation to the United States, but Cuban revolutionary leader José Martí called for Cuban nationhood. When the U.S. battleship Maine sank in Havana Harbor, the U.S. blamed Spain and the Spanish–American War broke out in 1898. After the U.S. won, Spain relinquished claim of sovereignty over territories, including Cuba. The U.S. administered Cuba as a protectorate until 1902. Several decades later in 1959, the corrupt Cuban government of U.S.-backed Fulgencio Batista was overthrown by Fidel Castro. Castro installed a Marxist–Leninist government allied with the Soviet Union, which has been in power ever since.
What government did Castro install?
Marxist–Leninist government
