The Qing dynasty (16441911) was founded after the fall of the Ming, the last Han Chinese dynasty, by the Manchus. The Manchus were formerly known as the Jurchens. When Beijing was captured by Li Zicheng's peasant rebels in 1644, the Chongzhen Emperor, the last Ming emperor, committed suicide. The Manchus then allied with former Ming general Wu Sangui and seized control of Beijing, which became the new capital of the Qing dynasty. The Mancus adopted the Confucian norms of traditional Chinese government in their rule of China proper. Schoppa, the editor of The Columbia Guide to Modern Chinese History argues, "A date around 1780 as the beginning of modern China is thus closer to what we know today as historical 'reality'. It also allows us to have a better baseline to understand the precipitous decline of the Chinese polity in the nineteenth and twentieth centuries."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did the last Ming Emperor commit suicide?
Ah, so.. Beijing was captured by Li Zicheng's peasant rebels

The Famicom contained no lockout hardware and, as a result, unlicensed cartridges (both legitimate and bootleg) were extremely common throughout Japan and the Far East. The original NES (but not the top-loading NES-101) contained the 10NES lockout chip, which significantly increased the challenges faced by unlicensed developers. Tinkerers at home in later years discovered that disassembling the NES and cutting the fourth pin of the lockout chip would change the chip's mode of operation from "lock" to "key", removing all effects and greatly improving the console's ability to play legal games, as well as bootlegs and converted imports. NES consoles sold in different regions had different lockout chips, so games marketed in one region would not work on consoles from another region. Known regions are: USA/Canada (3193 lockout chip), most of Europe (3195), Asia (3196) and UK, Italy and Australia (3197). Since two types of lockout chip were used in Europe, European NES game boxes often had an "A" or "B" letter on the front, indicating whether the game is compatible with UK/Italian/Australian consoles (A), or the rest of Europe (B). Rest-of-Europe games typically had text on the box stating "This game is not compatible with the Mattel or NES versions of the Nintendo Entertainment System". Similarly, UK/Italy/Australia games stated "This game is only compatible with the Mattel or NES versions of the Nintendo Entertainment System".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the lockout chip number for South Africa?
Ah, so.. unanswerable

In 1957, Braunstein further demonstrated that the rudimentary devices could be used for non-radio communication across a short distance. As noted by Kroemer Braunstein".. had set up a simple optical communications link: Music emerging from a record player was used via suitable electronics to modulate the forward current of a GaAs diode. The emitted light was detected by a PbS diode some distance away. This signal was fed into an audio amplifier, and played back by a loudspeaker. Intercepting the beam stopped the music. We had a great deal of fun playing with this setup." This setup presaged the use of LEDs for optical communication applications.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What final device was needed to hear the signal from the initial GaAs diode?
Ah, so..
audio amplifier
