Article: On the other hand, I2a1b1 (P41.2) is typical of the South Slavic populations, being highest in Bosnia-Herzegovina (>50%). Haplogroup I2a2 is also commonly found in north-eastern Italians. There is also a high concentration of I2a2a in the Moldavian region of Romania, Moldova and western Ukraine. According to original studies, Hg I2a2 was believed to have arisen in the west Balkans sometime after the LGM, subsequently spreading from the Balkans through Central Russian Plain. Recently, Ken Nordtvedt has split I2a2 into two clades – N (northern) and S (southern), in relation where they arose compared to Danube river. He proposes that N is slightly older than S. He recalculated the age of I2a2 to be ~ 2550 years and proposed that the current distribution is explained by a Slavic expansion from the area north-east of the Carpathians.

Question: Haplogroup I2a2 is commonly found in what group of people?
Ans: north-eastern Italians


Here is a question about this article: The Manchus sent Han Bannermen to fight against Koxinga's Ming loyalists in Fujian. The Qing carried out a massive depopulation policy and seaban forcing people to evacuated the coast in order to deprive Koxinga's Ming loyalists of resources, this has led to a myth that it was because Manchus were "afraid of water". In Fujian, it was Han Bannermen who were the ones carrying out the fighting and killing for the Qing and this disproved the entirely irrelevant claim that alleged fear of the water on part of the Manchus had to do with the coastal evacuation and seaban. Even though a poem refers to the soldiers carrying out massacres in Fujian as "barbarian", both Han Green Standard Army and Han Bannermen were involved in the fighting for the Qing side and carried out the worst slaughter. 400,000 Green Standard Army soldiers were used against the Three Feudatories besides 200,000 Bannermen.
What is the answer to this question: Who did the Manchus send to battle Koxinga's troops?
****
So... Han Bannermen


The problem: Answer a question about this article:
The term "high fidelity" was coined in the 1920s by some manufacturers of radio receivers and phonographs to differentiate their better-sounding products claimed as providing "perfect" sound reproduction. The term began to be used by some audio engineers and consumers through the 1930s and 1940s. After 1949 a variety of improvements in recording and playback technologies, especially stereo recordings, which became widely available in 1958, gave a boost to the "hi-fi" classification of products, leading to sales of individual components for the home such as amplifiers, loudspeakers, phonographs, and tape players. High Fidelity and Audio were two magazines that hi-fi consumers and engineers could read for reviews of playback equipment and recordings.
What happened in 1958 that changed the home music scene?
****
The answer: variety of improvements in recording and playback technologies


Problem: Please answer a question about the following article about LaserDisc:
LaserDisc had a number of advantages over VHS. It featured a far sharper picture with a horizontal resolution of 425 TVL lines for NTSC and 440 TVL lines for PAL discs, while VHS featured only 240 TVL lines with NTSC. It could handle analog and digital audio where VHS was mostly analog only (VHS can have PCM audio in professional applications but is uncommon), and the NTSC discs could store multiple audio tracks. This allowed for extras like director's commentary tracks and other features to be added onto a film, creating "Special Edition" releases that would not have been possible with VHS. Disc access was random and chapter based, like the DVD format, meaning that one could jump to any point on a given disc very quickly. By comparison, VHS would require tedious rewinding and fast-forwarding to get to specific points.
Which medium was chapter based like DVD format, Laserdisc or VHS?
A: LaserDisc

iPods have been criticized for alleged short life-span and fragile hard drives. A 2005 survey conducted on the MacInTouch website found that the iPod line had an average failure rate of 13.7% (although they note that comments from respondents indicate that "the true iPod failure rate may be lower than it appears"). It concluded that some models were more durable than others. In particular, failure rates for iPods employing hard drives was usually above 20% while those with flash memory had a failure rate below 10%. In late 2005, many users complained that the surface of the first generation iPod Nano can become scratched easily, rendering the screen unusable. A class action lawsuit was also filed. Apple initially considered the issue a minor defect, but later began shipping these iPods with protective sleeves.[citation needed]

What did Apple include with the iPod to resolve the screen problem?
Answer: protective sleeves


In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6] Here his parents continued running their boarding house for male students; the Chopin Family Parlour (Salonik Chopinów) became a museum in the 20th century. In 1829 the artist Ambroży Mieroszewski executed a set of portraits of Chopin family members, including the first known portrait of the composer.[n 7]
What was the Chopin family's business?
boarding house for male students
