Question: Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President Thomas Jefferson with his slave Sally Hemings. As noted in the 2012 collaborative Smithsonian-Monticello exhibit, Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of Madison Hemings, who continued to identify as black, some in future generations eventually identified as white and "married out", while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.

Question: Qing China reached its largest extent during the 18th century, when it ruled China proper (eighteen provinces) as well as the areas of present-day Northeast China, Inner Mongolia, Outer Mongolia, Xinjiang and Tibet, at approximately 13 million km2 in size. There were originally 18 provinces, all of which in China proper, but later this number was increased to 22, with Manchuria and Xinjiang being divided or turned into provinces. Taiwan, originally part of Fujian province, became a province of its own in the late 19th century, but was ceded to the Empire of Japan in 1895 following the First Sino-Japanese War. In addition, many surrounding countries, such as Korea (Joseon dynasty), Vietnam frequently paid tribute to China during much of this period. Khanate of Kokand were forced to submit as protectorate and pay tribute to the Qing dynasty in China between 1774 and 1798.
Is there an answer to this question: What century did Qing China stretch to its largest?

Answer: 18th century

Question: It was the pub that first introduced the concept of the bar counter being used to serve the beer. Until that time beer establishments used to bring the beer out to the table or benches, as remains the practice in (for example) beer gardens and other drinking establishments in Germany. A bar might be provided for the manager to do paperwork while keeping an eye on his or her customers, but the casks of ale were kept in a separate taproom. When the first pubs were built, the main room was the public room with a large serving bar copied from the gin houses, the idea being to serve the maximum number of people in the shortest possible time. It became known as the public bar[citation needed]. The other, more private, rooms had no serving barthey had the beer brought to them from the public bar. There are a number of pubs in the Midlands or the North which still retain this set up but these days the beer is fetched by the customer from the taproom or public bar. One of these is The Vine, known locally as The Bull and Bladder, in Brierley Hill near Birmingham, another the Cock at Broom, Bedfordshire a series of small rooms served drinks and food by waiting staff. In the Manchester district the public bar was known as the "vault", other rooms being the lounge and snug as usual elsewhere. By the early 1970s there was a tendency to change to one large drinking room and breweries were eager to invest in interior design and theming.
Is there an answer to this question: What establishments inspired pubs to set up serving bars?

Answer: gin houses

Question: 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".
