Input: Article: Like any plucked instrument, mandolin notes decay to silence rather than sound out continuously as with a bowed note on a violin, and mandolin notes decay faster than larger stringed instruments like the guitar. This encourages the use of tremolo (rapid picking of one or more pairs of strings) to create sustained notes or chords. The mandolin's paired strings facilitate this technique: the plectrum (pick) strikes each of a pair of strings alternately, providing a more full and continuous sound than a single string would.

Now answer this question: What parts of the mandolin faciliate the tremolo technique?

Output: paired strings

Article: In 1565, the powerful Rinbung princes were overthrown by one of their own ministers, Karma Tseten who styled himself as the Tsangpa, "the one of Tsang", and established his base of power at Shigatse. The second successor of this first Tsang king, Karma Phuntsok Namgyal, took control of the whole of Central Tibet (U-Tsang), reigning from 16111621. Despite this, the leaders of Lhasa still claimed their allegiance to the Phagmodru as well as the Gelug, while the U-Tsang king allied with the Karmapa. Tensions rose between the nationalistic U-Tsang ruler and the Mongols who safeguarded their Mongol Dalai Lama in Lhasa. The fourth Dalai Lama refused to give an audience to the U-Tsang king, which sparked a conflict as the latter began assaulting Gelug monasteries. Chen writes of the speculation over the fourth Dalai Lama's mysterious death and the plot of the U-Tsang king to have him murdered for "cursing" him with illness, although Chen writes that the murder was most likely the result of a feudal power struggle. In 1618, only two years after Yonten Gyatso died, the Gelug and the Karma Kargyu went to war, the Karma Kargyu supported by the secular U-Tsang king. The U-Tsang ruler had a large number of Gelugpa lamas killed, occupied their monasteries at Drepung and Sera, and outlawed any attempts to find another Dalai Lama. In 1621, the U-Tsang king died and was succeeded by his young son Karma Tenkyong, an event which stymied the war effort as the latter accepted the six-year-old Lozang Gyatso as the new Dalai Lama. Despite the new Dalai Lama's diplomatic efforts to maintain friendly relations with the new U-Tsang ruler, Sonam Rapten (15951657), the Dalai Lama's chief steward and treasurer at Drepung, made efforts to overthrow the U-Tsang king, which led to another conflict. In 1633, the Gelugpas and several thousand Mongol adherents defeated the U-Tsang king's troops near Lhasa before a peaceful negotiation was settled. Goldstein writes that in this the "Mongols were again playing a significant role in Tibetan affairs, this time as the military arm of the Dalai Lama."

Question: When were the Rinbung princes overthrown?
Ans: 1565

Here is a question about this article: A novelty shop called Au Bon Marche had been founded in Paris in 1838 to sell lace, ribbons, sheets, mattresses, buttons, umbrellas and other assorted goods. It originally had four departments, twelve employees, and a floor space of three hundred meters. The entrepreneur Aristide Boucicaut became a partner in 1852, and changed the marketing plan, instituting fixed prices and guarantees that allowed exchanges and refunds, advertising, and a much wider variety of merchandise. The annual income of the store increased from 500,000 francs in 1852 to five million in 1860. In 1869 he built much larger building at 24 rue de Sevres on the Left Bank, and enlarged the store again in 1872, with help from the engineering firm of Gustave Eiffel, creator of the Eiffel Tower. The income rose from twenty million francs in 1870 to 72 million at the time of the Boucicaut's death in 1877. The floor space had increased from three hundred square meters in 1838 to fifty thousand, and the number of employees had increased from twelve in 1838 to 1788 in 1879. Boucicaut was famous for his marketing innovations; a reading room for husbands while their wives shopped; extensive newspaper advertising; entertainment for children; and six million catalogs sent out to customers. By 1880 half the employees were women; unmarried women employees lived in dormitories on the upper floors.
What is the answer to this question: What was the change in profit to Au Bon Marche after these changes?
****
So... increased from 500,000 francs in 1852 to five million in 1860

The problem: Answer a question about this article:
According to Genius, the James Gleick-authored biography, Feynman tried LSD during his professorship at Caltech. Somewhat embarrassed by his actions, he largely sidestepped the issue when dictating his anecdotes; he mentions it in passing in the "O Americano, Outra Vez" section, while the "Altered States" chapter in Surely You're Joking, Mr. Feynman! describes only marijuana and ketamine experiences at John Lilly's famed sensory deprivation tanks, as a way of studying consciousness. Feynman gave up alcohol when he began to show vague, early signs of alcoholism, as he did not want to do anything that could damage his brainthe same reason given in "O Americano, Outra Vez" for his reluctance to experiment with LSD.
In what book did he talk about his LSD use?
****
The answer: O Americano, Outra Vez

Question: Read this and answer the question

An alternative concept is that they formed closer to the Sun, where the matter density was higher, and then subsequently migrated to their current orbits after the removal of the gaseous protoplanetary disc. This hypothesis of migration after formation is favoured, due to its ability to better explain the occupancy of the populations of small objects observed in the trans-Neptunian region. The current most widely accepted explanation of the details of this hypothesis is known as the Nice model, which explores the effect of a migrating Neptune and the other giant planets on the structure of the Kuiper belt.

If Neptune formed closer to the sun, what caused it to migrate to it's current orbit?
Answer:
removal of the gaseous protoplanetary disc
