Question: Passage: After graduation, Shostakovich initially embarked on a dual career as concert pianist and composer, but his dry style of playing was often unappreciated (his American biographer, Laurel Fay, comments on his "emotional restraint" and "riveting rhythmic drive"). He nevertheless won an "honorable mention" at the First International Chopin Piano Competition in Warsaw in 1927. He attributed the disappointment at the competition to suffering from appendicitis and the jury being all-Polish. He had his appendix removed in April 1927. After the competition Shostakovich met the conductor Bruno Walter, who was so impressed by the composer's First Symphony that he conducted it at its Berlin premiere later that year. Leopold Stokowski was equally impressed and gave the work its U.S. premiere the following year in Philadelphia and also made the work's first recording.
Shostakovich concentrated on composition thereafter and soon limited his performances primarily to those of his own works. In 1927 he wrote his Second Symphony (subtitled To October), a patriotic piece with a great pro-Soviet choral finale. Owing to its experimental nature, as with the subsequent Third Symphony, it was not critically acclaimed with the enthusiasm given to the First.
1927 also marked the beginning of Shostakovich's relationship with Ivan Sollertinsky, who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Mahler, which had a strong influence on his music from the Fourth Symphony onwards.
While writing the Second Symphony, Shostakovich also began work on his satirical opera The Nose, based on the story by Nikolai Gogol. In June 1929, against the composer's own wishes, the opera was given a concert performance; it was ferociously attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread incomprehension among musicians.In the late 1920s and early 1930s, Shostakovich worked at TRAM, a proletarian youth theatre. Although he did little work in this post, it shielded him from ideological attack. Much of this period was spent writing his opera, Lady Macbeth of the Mtsensk District, which was first performed in 1934. It was immediately successful, on both popular and official levels. It was described as "the result of the general success of Socialist construction, of the correct policy of the Party", and as an opera that "could have been written only by a Soviet composer brought up in the best tradition of Soviet culture".Shostakovich married his first wife, Nina Varzar, in 1932. Initial difficulties led to a divorce in 1935, but the couple soon remarried when Nina became pregnant with their first child, Galina. 
Question: What is the name of the composer whose First Symphony was conducted by Bruno Walter at its Berlin premiere?

Answer: Shostakovich.


Question: Passage: Franklin Bean is shown in flashback with his father, a postal worker at his high school. His poor performance is attributed to a lack of discipline which a school officials assures the elder Bean can be fixed with a stint in the Army. Then, in present day, PFC Bean is attending his father's funeral before returning to his duty station in Germany. In his state of grief he gets drunk, punches an MP and breaks through a plate-glass window in a local bar. Bean's army lawyer secures a plea deal, struck by his attorney Captain Ramon Garcia, in lieu of a court martial which involves him removing unauthorized tattoos from his hands (obtained during his drunken rampage), paying for a broken window and serving 90 days in the camp stockade. He is met at the gates by a decorated Korean War veteran Master Sergeant named Otis McKinney. 
McKinney explains that the stockade is fairly small and, as a result, he is in complete charge of the compound while being supported by two guards; Corporals Harold Lamar and Gerald Gessner. Bean finds a sympathetic ear in stockade guard Corporal Lamar after learning he is just as afraid of McKinney and only "serving his own time." Gessner is a somewhat spineless lackey to McKinney whom he clearly admires and respects. 
Question: What is the last name of the person whose poor performance is attributed to a lack of discipline?

Answer: Bean.


Question: Passage: The Li family belonged to the northwest military aristocracy prevalent during the Sui dynasty and claimed to be paternally descended from the Daoist founder, Laozi (whose personal name was Li Dan or Li Er) the Han dynasty General Li Guang and Western Liang ruler Li Gao.  This family was known as the Longxi Li lineage (Li lineage; 隴西李氏), which includes the Tang poet Li Bai.  The Tang Emperors also had Xianbei maternal ancestry, from Emperor Gaozu of Tang's Xianbei mother, Duchess Dugu.
Li Yuan was Duke of Tang and governor of Taiyuan, modern Shanxi, during the Sui dynasty's collapse, which was caused in part by the Sui failure to conquer the northern part of the Korean peninsula during the Goguryeo–Sui War. He had prestige and military experience, and was a first cousin of Emperor Yang of Sui (their mothers were sisters). Li Yuan rose in rebellion in 617, along with his son and his equally militant daughter Princess Pingyang (d. 623), who raised and commanded her own troops. In winter 617, Li Yuan occupied Chang'an, relegated Emperor Yang to the position of Taishang Huang or retired emperor, and acted as regent to the puppet child-emperor, Yang You. On the news of Emperor Yang's murder by General Yuwen Huaji on June 18, 618, Li Yuan declared himself the emperor of a new dynasty, the Tang.Li Yuan, known as Emperor Gaozu of Tang, ruled until 626, when he was forcefully deposed by his son Li Shimin, the Prince of Qin.  Li Shimin had commanded troops since the age of 18, had prowess with bow and arrow, sword and lance and was known for his effective cavalry charges.  Fighting a numerically superior army, he defeated Dou Jiande (573–621) at Luoyang in the Battle of Hulao on May 28, 621.  In a violent elimination of royal family due to fear of assassination, Li Shimin ambushed and killed two of his brothers, Li Yuanji (b. 603) and Crown prince Li Jiancheng (b. 589), in the Xuanwu Gate Incident on July 2, 626.  Shortly thereafter, his father abdicated in his favor and Li Shimin ascended the throne.  He is conventionally known by his temple name Taizong.
Although killing two brothers and deposing his father contradicted the Confucian value of filial piety, Taizong showed himself to be a capable leader who listened to the advice of the wisest members of his council.  In 628, Emperor Taizong held a Buddhist memorial service for the casualties of war, and in 629 he had Buddhist monasteries erected at the sites of major battles so that monks could pray for the fallen on both sides of the fight.  This was during the Tang campaign against the Eastern Turks, a Turkic Khaganate that was destroyed after the capture of its ruler, Illig Qaghan by the famed Tang military officer Li Jing (571–649); who later became a Chancellor of the Tang dynasty. With this victory, the Turks accepted Taizong as their khagan, a title rendered as Tian Kehan in addition to his rule as emperor of China under the traditional title "Son of Heaven". 
Question: What was the name of the Prince of Qin?

Answer:
Li Shimin.
