Q: I have a test where I am given the following article, what is an answer for the question: What is the last name of the person who is described as having the polar virus in his blood? ?  In July 1873 the U.S. Navy dispatched USS Juniata to Greenland, to search for survivors from the Polaris expedition which had disintegrated after the death of its leader, Charles Francis Hall. Juniata's second-in-command was George W. De Long, a 28-year-old graduate of the United States Naval Academy, making his first visit to the Arctic. Ice conditions prevented Juniata from advancing beyond Upernavik; De Long volunteered to take the ship's tender, a small steamer named the Little Juniata, in the hope of finding survivors at Cape York, a further 400 nautical miles (740 km) north.The attempt failed; Little Juniata faced extreme weather conditions, and was forced to retreat a few miles from Cape York. De Long returned to Juniata in mid-August, having found no trace of the Polaris crew—who had meanwhile been rescued by the Scottish whaler SS Ravenscraig—but the experience had profoundly affected his outlook. Having earlier described the Greenland coast in a letter to his wife Emma as "a dreary land of desolation ... I hope I may never find myself cast away in such a perfectly God-forsaken place", he returned home captivated by the Arctic. Emma wrote: "The polar virus was in his blood and would not let him rest".The abortive Little Juniata mission brought De Long to public notice, and he saw himself as a possible leader of the next U.S. Arctic expedition. He approached Henry Grinnell, the philanthropic shipping magnate who had funded several previous expeditions. Grinnell was not prepared to offer financial support, instead advising De Long to approach James Gordon Bennett Jr., owner and publisher of the New York Herald and a known sponsor of bold schemes. De Long met Bennett in New York early in 1874; the newspaperman was impressed by De Long, and assured him that his Arctic ambitions would have the enthusiastic support of the Herald. In the meantime De Long had applied to the Navy Department for an Arctic command, a request that he was informed would "receive due attention".

Q: I have a test where I am given the following article, what is an answer for the question: What is the last name of the person whose main performance success during this period was his playing of Mozart's D minor Piano Concerto at a concert celebrating the centenary of Mozart's birth, in January 1856? ?  In the years between 1854 and 1856 Smetana suffered a series of personal blows. In July 1854 his second daughter, Gabriela, died of tuberculosis. A year later his eldest daughter Bedřiška, who at the age of four was showing signs of musical precocity, died of scarlet fever. Smetana wrote his Piano Trio in G minor as a tribute to her memory; it was performed in Prague on 3 December 1855 and, according to the composer, was received "harshly" by the critics, although Liszt praised it. Smetana's sorrows continued; just after Bedřiška's death a fourth daughter, Kateřina, had been born but she, too, died in June 1856. By this time Smetana's wife Kateřina had also been diagnosed with tuberculosis.In July 1856, Smetana received news of the death in exile of his revolutionary friend Karel Havlíček. The political climate in Prague was a further source of gloom; hopes of a more enlightened government and social reform following Franz Joseph's accession in 1848 had faded as Austrian absolutism reasserted itself under Baron Alexander von Bach. Despite the good name of the Piano Institute, Smetana's status as a concert pianist was generally considered below that of contemporaries such as Alexander Dreyschock. Critics acknowledged Smetana's "delicate, crystalline touch", closer in style to Chopin than Liszt, but believed that his physical frailty was a serious drawback to his concert-playing ambitions. His main performance success during this period was his playing of Mozart's D minor Piano Concerto at a concert celebrating the centenary of Mozart's birth, in January 1856. His disenchantment with Prague was growing and, perhaps influenced by Dreyschock's accounts of opportunities in Sweden, Smetana decided to seek success there. On 11 October 1856, after writing to his parents that "Prague did not wish to acknowledge me, so I left it", he departed for Gothenburg.

Q: I have a test where I am given the following article, what is an answer for the question: What is the last name of the person who was not surprised that the band was looking for a replacement for him? ?  In September 2010, Mikael Åkerfeldt stated that he was writing for a new Opeth album. The band announced on their website that they would start recording their tenth album on January 31, 2011, at the Atlantis/Metronome studios in Stockholm, once again with Jens Bogren (engineering) and Steven Wilson from Porcupine Tree as co-producer.Shortly after mixing was complete on the new album in April 2011, Opeth announced that Per Wiberg was relieved of his duties in the band. In the press statement, Mikael Åkerfeldt explained the decision, saying, "Mendez, Axe and Fredrik and I came to the decision that we should find a replacement for Per right after the recordings of the new album, and this came as no surprise to Per. He had, in turn, been thinking about leaving, so you could say it was a mutual decision. There's no bad blood, just a relationship that came to an end, and that's that."Opeth's tenth album, Heritage, was released on September 14, 2011, to generally favorable reviews. The album sold 19,000 copies in the United States in its first week of release and debuted at number 19 on the Billboard 200 chart. Heritage debuted at number four in the band's native country of Sweden.Heritage became the second Opeth album to not feature any death growls and had a much more progressive style than previous albums from the band, something that Åkerfeldt had been wanting to do for some time.The first two songs Åkerfeldt wrote for Heritage were in the style of Watershed. After hearing the songs for the first time, Martín Méndez told Åkerfeldt that he would be disappointed if the album continued in that direction. Relieved that Méndez was not interested in doing another conventional Opeth album, Åkerfeldt scrapped the two songs and started the writing process over in a different style. In the press release for Heritage, Mikael Åkerfeldt revealed that he felt as though he had been building to write the album since he was 19 years old. In a review for Allmusic, Thom Jurek called Heritage the band's most adventurous album,...
