Input: Article: Despite these crises, the 14th century was also a time of great progress in the arts and sciences. Following a renewed interest in ancient Greek and Roman texts that took root in the High Middle Ages, the Italian Renaissance began. The absorption of Latin texts had started before the Renaissance of the 12th century through contact with Arabs during the Crusades, but the availability of important Greek texts accelerated with the capture of Constantinople by the Ottoman Turks, when many Byzantine scholars had to seek refuge in the West, particularly Italy.

Now answer this question: Which conflicts brought Europeans into contact with Arabs prior to the 12th century?

Output: the Crusades

Article: At the end of 1831, Chopin received the first major endorsement from an outstanding contemporary when Robert Schumann, reviewing the Op. 2 Variations in the Allgemeine musikalische Zeitung (his first published article on music), declared: "Hats off, gentlemen! A genius." On 26 February 1832 Chopin gave a debut Paris concert at the Salle Pleyel which drew universal admiration. The critic Francois-Joseph Fetis wrote in the Revue et gazette musicale: "Here is a young man who ... taking no model, has found, if not a complete renewal of piano music, ... an abundance of original ideas of a kind to be found nowhere else ..." After this concert, Chopin realized that his essentially intimate keyboard technique was not optimal for large concert spaces. Later that year he was introduced to the wealthy Rothschild banking family, whose patronage also opened doors for him to other private salons (social gatherings of the aristocracy and artistic and literary elite). By the end of 1832 Chopin had established himself among the Parisian musical elite, and had earned the respect of his peers such as Hiller, Liszt, and Berlioz. He no longer depended financially upon his father, and in the winter of 1832 he began earning a handsome income from publishing his works and teaching piano to affluent students from all over Europe. This freed him from the strains of public concert-giving, which he disliked.

Question: Once Chopin stopped performing concerts, how did he earn his income?
Ans: publishing his works and teaching piano to affluent students

Here is a question about this article: Kerry's commanding officer, Lieutenant Commander George Elliott, stated to Douglas Brinkley in 2003 that he did not know whether to court-martial Kerry for beaching the boat without orders or give him a medal for saving the crew. Elliott recommended Kerry for the Silver Star, and Zumwalt flew into An Thoi to personally award medals to Kerry and the rest of the sailors involved in the mission. The Navy's account of Kerry's actions is presented in the original medal citation signed by Zumwalt. The engagement was documented in an after-action report, a press release written on March 1, 1969, and a historical summary dated March 17, 1969.
What is the answer to this question: Who was Kerry's commander?
****
So... Lieutenant Commander George Elliott

The problem: Answer a question about this article:
Charlemagne planned to continue the Frankish tradition of dividing his kingdom between all his heirs, but was unable to do so as only one son, Louis the Pious (r. 814840), was still alive by 813. Just before Charlemagne died in 814, he crowned Louis as his successor. Louis's reign of 26 years was marked by numerous divisions of the empire among his sons and, after 829, civil wars between various alliances of father and sons over the control of various parts of the empire. Eventually, Louis recognised his eldest son Lothair I (d. 855) as emperor and gave him Italy. Louis divided the rest of the empire between Lothair and Charles the Bald (d. 877), his youngest son. Lothair took East Francia, comprising both banks of the Rhine and eastwards, leaving Charles West Francia with the empire to the west of the Rhineland and the Alps. Louis the German (d. 876), the middle child, who had been rebellious to the last, was allowed to keep Bavaria under the suzerainty of his elder brother. The division was disputed. Pepin II of Aquitaine (d. after 864), the emperor's grandson, rebelled in a contest for Aquitaine, while Louis the German tried to annex all of East Francia. Louis the Pious died in 840, with the empire still in chaos.
How long did Louis the Pious reign?
****
The answer: 26 years

Problem: Please answer a question about the following article about Muammar Gaddafi:
In 1979, the U.S. placed Libya on its list of "State Sponsors of Terrorism", while at the end of the year a demonstration torched the U.S. embassy in Tripoli in solidarity with the perpetrators of the Iran hostage crisis. The following year, Libyan fighters began intercepting U.S. fighter jets flying over the Mediterranean, signalling the collapse of relations between the two countries. Libyan relations with Lebanon and Shi'ite communities across the world also deteriorated due to the August 1978 disappearance of imam Musa al-Sadr when visiting Libya; the Lebanese accused Gaddafi of having him killed or imprisoned, a charge he denied. Relations with Syria improved, as Gaddafi and Syrian President Hafez al-Assad shared an enmity with Israel and Egypt's Sadat. In 1980, they proposed a political union, with Libya paying off Syria's 1 billion debt to the Soviet Union; although pressures led Assad to pull out, they remained allies. Another key ally was Uganda, and in 1979, Gaddafi sent 2,500 troops into Uganda to defend the regime of President Idi Amin from Tanzanian invaders. The mission failed; 400 Libyans were killed and they were forced to retreat. Gaddafi later came to regret his alliance with Amin, openly criticising him.
How much money did Syria owe to the Soviets as of 1980?
A: 1 billion

Question: Read this and answer the question

Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the mammalian brain. If distinguished from reactive responses of reptiles, emotions would then be mammalian elaborations of general vertebrate arousal patterns, in which neurochemicals (for example, dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures and postures. Emotions can likely be mediated by pheromones (see fear).

What classification of chemicals do dopamine, serotonin and noradrenaline belong to?
Answer:
neurochemicals
