Question: Passage: Caspar David Friedrich was born on 5 September 1774, in Greifswald, Swedish Pomerania, on the Baltic coast of Germany. The sixth of ten children, he was brought up in the strict Lutheran creed of his father Adolf Gottlieb Friedrich, a candle-maker and soap boiler. Records of the family's financial circumstances are contradictory; while some sources indicate the children were privately tutored, others record that they were raised in relative poverty. Caspar David was familiar with death from an early age. His mother, Sophie Dorothea Bechly, died in 1781 when he was just seven. A year later, his sister Elisabeth died, while a second sister, Maria, succumbed to typhus in 1791. Arguably the greatest tragedy of his childhood happened in 1787 when his brother Johann Christoffer died: at the age of thirteen, Caspar David witnessed his younger brother fall through the ice of a frozen lake, and drown. Some accounts suggest that Johann Christoffer perished while trying to rescue Caspar David, who was also in danger on the ice.
Friedrich began his formal study of art in 1790 as a private student of artist Johann Gottfried Quistorp at the University of Greifswald in his home city, at which the art department is now named Caspar-David-Friedrich-Institut in his honour. Quistorp took his students on outdoor drawing excursions; as a result, Friedrich was encouraged to sketch from life at an early age. Through Quistorp, Friedrich met and was subsequently influenced by the theologian Ludwig Gotthard Kosegarten, who taught that nature was a revelation of God. Quistorp introduced Friedrich to the work of the German 17th-century artist Adam Elsheimer, whose works often included religious subjects dominated by landscape, and nocturnal subjects. During this period he also studied literature and aesthetics with Swedish professor Thomas Thorild. Four years later Friedrich entered the prestigious Academy of Copenhagen, where he began his education by making copies of casts from antique sculptures before proceeding to drawing from life. Living in Copenhagen afforded the young painter access to the Royal Picture Gallery's collection of 17th-century Dutch landscape painting. At the Academy he studied under teachers such as Christian August Lorentzen and the landscape painter Jens Juel. These artists were inspired by the Sturm und Drang movement and represented a midpoint between the dramatic intensity and expressive manner of the budding Romantic aesthetic and the waning neo-classical ideal. Mood was paramount, and influence was drawn from such sources as the Icelandic legend of Edda, the poems of Ossian and Norse mythology. 
Question: What is the full name of the man who taught taught that nature was a revelation of God to the person who lost his mother when he was seven?

Answer: Ludwig Gotthard Kosegarten.


Question: Passage: Wyoming's territorial Governor Francis E. Warren visited Rock Springs on September 3, 1885, the day after the riot, to make a personal assessment. After his trip to Rock Springs, Warren traveled to Evanston, where he sent telegrams to U.S. President Grover Cleveland appealing for federal troops. Back in Rock Springs, the riot had calmed, but the situation was still unstable. Two companies of the United States Army's 7th Infantry arrived on September 5, 1885. One company, under the command of a Lieutenant Colonel Anderson, was stationed in Evanston, Wyoming; the other, under a Colonel Chipman, was stationed in Rock Springs. At Camp Murray, Utah Territory, Colonel Alexander McDowell McCook was ordered to augment the garrison sent to Wyoming with six more companies.On September 9, 1885, one week after the massacre, six companies of soldiers arrived in Wyoming. Four of the six companies then escorted the Chinese back to Rock Springs. Once back in Rock Springs, the Chinese laborers found scorched tracts of land where their homes once stood. The mining company had buried only a few dead; others remained lying in the open, mangled, decomposing, and partially eaten by dogs, hogs, or other animals.The situation in Rock Springs was stabilized as early as September 15, when Warren first requested the removal of federal troops, but the mines at Rock Springs remained closed for a time. On September 30, 1885, white miners, mostly Finnish immigrants who were members of the Knights of Labor, walked out of mines in Carbon County, Wyoming, in protest of the company's continued use of Chinese miners. In Rock Springs, the white miners were not back at work in late September, because the company still used Chinese labor. Rock Springs steadily became quieter, and, on October 5, 1885, emergency troops, except for two companies, were removed. However, the temporary posts of Camp Medicine Butte, established in Evanston, and of Camp Pilot Butte, in Rock Springs, remained long after the riot. Camp Pilot Butte closed in 1899 after the onset of the Spanish–American War.The labor strike was unsuccessful, and the miners went back to work within a couple of months. The national Knights of Labor organization refused to support the Carbon strike and the hold out by white miners in Rock Springs following the Rock Springs Riot. The organization avoided supporting the miners along the Union Pacific Railroad, because it did not want to be seen as condoning the violence at Rock Springs. When the Union Pacific Coal Department reopened the mines, it fired 45 white miners connected to the violence. 
Question: What company fired 45 white miners?

Answer: Union Pacific Coal Department.


Question: Passage: Balakirev's despotism strained the relationship between him and Tchaikovsky but both men still appreciated each other's abilities. Despite their friction, Balakirev proved the only man to persuade Tchaikovsky to rewrite a work several times, as he would with Romeo and Juliet. At Balakirev's suggestion, Tchaikovsky based the work on Balakirev's King Lear, a tragic overture in sonata form after the example of Beethoven's concert overtures. It was Tchaikovsky's idea to reduce the plot to one central conflict and represent it musically with the binary structure of sonata form. However, the execution of that plot in the music we know today came only after two radical revisions. Balakirev discarded many of the early drafts Tchaikovsky sent him and, with the flurry of suggestions between the two men, the piece was constantly in the mail between Moscow and Saint Petersburg.Tchaikovsky allowed the first version to be premiered by Nikolai Rubinstein on March 16, 1870, after the composer had incorporated only some of Balakirev's suggestions. The premiere was a disaster. Stung by this rejection, Tchaikovsky took Balakirev's strictures to heart. He forced himself to reach beyond his musical training and rewrote much of the music into the form we know it today. Romeo would bring Tchaikovsky his first national and international acclaim and become a work the kuchka lauded unconditionally. On hearing the love theme from Romeo, Stasov told the group, "There were five of you; now there are six". Such was the enthusiasm of the Five for Romeo that at their gatherings Balakirev was always asked to play it through at the piano. He did this so many times that he learned to perform it from memory.Some critics, among them Tchaikovsky biographers Lawrence and Elisabeth Hanson, have wondered what would have happened if Tchaikovsky had joined Balakirev in 1862 instead of attending the Conservatory. They suggest that he might have developed much more quickly as an independent composer, and offer as proof the fact that Tchaikovsky did not write his first wholly distinct work until Balakirev goaded and inspired him to write Romeo. How well Tchaikovsky might have developed in the long run is another matter. He owed much of his musical ability, including his skill at orchestration, to the thorough grounding in counterpoint, harmony and musical theory he received at the Conservatory. Without that grounding, Tchaikovsky might not have been able to write what would become his greatest works. 
Question: What was the first names of Tchaikovsky's two biographers?

Answer:
Lawrence.
