Problem: Most samurai were bound by a code of honor and were expected to set an example for those below them. A notable part of their code is seppuku (切腹, seppuku?) or hara kiri, which allowed a disgraced samurai to regain his honor by passing into death, where samurai were still beholden to social rules. Whilst there are many romanticized characterizations of samurai behavior such as the writing of Bushido (武士道, Bushidō?) in 1905, studies of Kobudo and traditional Budō indicate that the samurai were as practical on the battlefield as were any other warrior.
How idealistic were samurai?
The answer is the following: as practical on the battlefield as were any other warrior

Problem: Chopin's output as a composer throughout this period declined in quantity year by year. Whereas in 1841 he had written a dozen works, only six were written in 1842 and six shorter pieces in 1843. In 1844 he wrote only the Op. 58 sonata. 1845 saw the completion of three mazurkas (Op. 59). Although these works were more refined than many of his earlier compositions, Zamoyski opines that "his powers of concentration were failing and his inspiration was beset by anguish, both emotional and intellectual."
What piece did Chopin compose in 1844?
The answer is the following: Op. 58 sonata

Problem: For the first several decades of disc record manufacturing, sound was recorded directly on to the "master disc" at the recording studio. From about 1950 on (earlier for some large record companies, later for some small ones) it became usual to have the performance first recorded on audio tape, which could then be processed and/or edited, and then dubbed on to the master disc. A record cutter would engrave the grooves into the master disc. Early versions of these master discs were soft wax, and later a harder lacquer was used. The mastering process was originally something of an art as the operator had to manually allow for the changes in sound which affected how wide the space for the groove needed to be on each rotation.
What was used in final recordings of vinyl records?
The answer is the following: harder lacquer

Problem: By the mid-18th century, the Qing had successfully put outer regions such as Inner and Outer Mongolia, Tibet and Xinjiang under its control. Imperial commissioners and garrisons were sent to Mongolia and Tibet to oversee their affairs. These territories were also under supervision of a central government institution called Lifan Yuan. Qinghai was also put under direct control of the Qing court. Xinjiang, also known as Chinese Turkestan, was subdivided into the regions north and south of the Tian Shan mountains, also known today as Dzungaria and Tarim Basin respectively, but the post of Ili General was established in 1762 to exercise unified military and administrative jurisdiction over both regions. Dzungaria was fully opened to Han migration by the Qianlong Emperor from the beginning. Han migrants were at first forbidden from permanently settling in the Tarim Basin but were the ban was lifted after the invasion by Jahangir Khoja in the 1820s. Likewise, Manchuria was also governed by military generals until its division into provinces, though some areas of Xinjiang and Northeast China were lost to the Russian Empire in the mid-19th century. Manchuria was originally separated from China proper by the Inner Willow Palisade, a ditch and embankment planted with willows intended to restrict the movement of the Han Chinese, as the area was off-limits to civilian Han Chinese until the government started colonizing the area, especially since the 1860s.
When did Tibet become part of Qing China?
The answer is the following:
