Article: Similar organizations in other countries followed: The American Anthropological Association in 1902, the Anthropological Society of Madrid (1865), the Anthropological Society of Vienna (1870), the Italian Society of Anthropology and Ethnology (1871), and many others subsequently. The majority of these were evolutionist. One notable exception was the Berlin Society of Anthropology (1869) founded by Rudolph Virchow, known for his vituperative attacks on the evolutionists. Not religious himself, he insisted that Darwin's conclusions lacked empirical foundation.

Question: When was the Berlin Society of Anthropology founded by Rudolph Virchow?
Ans: 1869


Here is a question about this article: Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans, at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acids—omega-3 and omega-6 fatty acids—seems also important for health, although definitive experimental demonstration has been elusive. Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (ALA), or taken in through marine food sources, serves as a building block for series 3 prostaglandins (e.g., weakly inflammatory PGE3). The omega-6 dihomo-gamma-linolenic acid (DGLA) serves as a building block for series 1 prostaglandins (e.g. anti-inflammatory PGE1), whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g. pro-inflammatory PGE 2). Both DGLA and AA can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins, which is one reason why a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids.
What is the answer to this question: At least how many fatty acids are essential to the human health and have to be consumed rather than produced by the body?
****
So... two


The problem: Answer a question about this article:
It is often said that Russia was militarily weak, technologically backward, and administratively incompetent. Despite its grand ambitions toward the south, it had not built its railroad network in that direction, and communications were poor. The bureaucracy was riddled with graft, corruption and inefficiency and was unprepared for war. Its navy was weak and technologically backward; its army, although very large, was good only for parades, suffered from colonels who pocketed their men's pay, poor morale, and was out of touch with the latest technology developed by Britain and France. By the war's end, everyone realized the profound weaknesses of the Russian military, and the Russian leadership was determined to reform it.
What did Russian colonels due to the men who served under them?
****
The answer: pocketed their men's pay


Problem: Please answer a question about the following article about Protestantism:
The name Anabaptist, meaning "one who baptizes again", was given them by their persecutors in reference to the practice of re-baptizing converts who already had been baptized as infants. Anabaptists required that baptismal candidates be able to make their own confessions of faith and so rejected baptism of infants. The early members of this movement did not accept the name Anabaptist, claiming that since infant baptism was unscriptural and null and void, the baptizing of believers was not a re-baptism but in fact their first real baptism. As a result of their views on the nature of baptism and other issues, Anabaptists were heavily persecuted during the 16th century and into the 17th by both Magisterial Protestants and Roman Catholics.[aa] While most Anabaptists adhered to a literal interpretation of the Sermon on the Mount, which precluded taking oaths, participating in military actions, and participating in civil government, some who practiced re-baptism felt otherwise.[ab] They were thus technically Anabaptists, even though conservative Amish, Mennonites, and Hutterites and some historians tend to consider them as outside of true Anabaptism. Anabaptist reformers of the Radical Reformation are diveded into Radical and the so-called Second Front. Some important Radical Reformation theologians were John of Leiden, Thomas Müntzer, Kaspar Schwenkfeld, Sebastian Franck, Menno Simons. Second Front Reformers included Hans Denck, Conrad Grebel, Balthasar Hubmaier and Felix Manz.
Who persecuted the Anabaptists in the 16th century?
A: Magisterial Protestants and Roman Catholics

In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700. It was also the first LD player to load from the front and not the top. One year earlier Hitachi introduced an expensive industrial player with a laser diode, but the player, which had poor picture quality due to an inadequate dropout compensator, was made only in limited quantities. After Pioneer released the LD-700, gas lasers were no longer used in consumer players, despite their advantages, although Philips continued to use gas lasers in their industrial units until 1985.

What was the name of the first solid-state laser consumer LaserDisc player?
Answer: LD-700


A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure. Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation.
How do some locomotives function in order to be more flexible in operation?
can switch to different supply voltages
