From roughly 115 to 60 BC, Han forces fought the Xiongnu over control of the oasis city-states in the Tarim Basin. Han was eventually victorious and established the Protectorate of the Western Regions in 60 BC, which dealt with the region's defense and foreign affairs. The Han also expanded southward. The naval conquest of Nanyue in 111 BC expanded the Han realm into what are now modern Guangdong, Guangxi, and northern Vietnam. Yunnan was brought into the Han realm with the conquest of the Dian Kingdom in 109 BC, followed by parts of the Korean Peninsula with the colonial establishments of Xuantu Commandery and Lelang Commandery in 108 BC. In China's first known nationwide census taken in 2 AD, the population was registered as having 57,671,400 individuals in 12,366,470 households.
When was the first national census taken in China?
2 AD

Input: Somalis
In the Middle Ages, several powerful Somali empires dominated the regional trade including the Ajuran Sultanate, which excelled in hydraulic engineering and fortress building, the Sultanate of Adal, whose general Ahmad ibn Ibrahim al-Ghazi (Ahmed Gurey) was the first commander to use cannon warfare on the continent during Adal's conquest of the Ethiopian Empire, and the Sultanate of the Geledi, whose military dominance forced governors of the Omani empire north of the city of Lamu to pay tribute to the Somali Sultan Ahmed Yusuf.

What state employed Abmad ibn Ibrahim al-Ghazi?
Output: the Sultanate of Adal

Input: Article: The space-consuming analog video signal of a LaserDisc limited playback duration to 30 minutes (CAV) or 60 minutes (CLV) per side because of the hardware manufacturer's refusal to reduce line count for increased playtime. After one side was finished playing, a disc has to be flipped over in order to continue watching a movie, and some titles fill two or more discs. Many players, especially units built after the mid-1980s, can "flip" discs automatically by rotating the optical pickup to the other side of the disc, but this is accompanied by a pause in the movie during the side change. If the movie is longer than what could be stored on two sides of a single disc, manually swapping to a second disc is necessary at some point during the film. One exception to this rule is the Pioneer LD-W1, which features two disc platters. In addition, perfect still frames and random access to individual still frames is limited only to the more expensive CAV discs, which only had a playing time of approximately 30 minutes per side. In later years, Pioneer and other manufacturers overcame this limitation by incorporating a digital memory buffer, which "grabbed" a single frame from a CLV disc.

Now answer this question: Which format allows for more playback tie per side, CLV or CAV?

Output: CLV

Article: After 14 years as editor, William Rees-Mogg resigned the post upon completion of the change of ownership. Murdoch began to make his mark on the paper by appointing Harold Evans as his replacement. One of his most important changes was the introduction of new technology and efficiency measures. In MarchMay 1982, following agreement with print unions, the hot-metal Linotype printing process used to print The Times since the 19th century was phased out and replaced by computer input and photo-composition. This allowed print room staff at The Times and The Sunday Times to be reduced by half. However, direct input of text by journalists ("single stroke" input) was still not achieved, and this was to remain an interim measure until the Wapping dispute of 1986, when The Times moved from New Printing House Square in Gray's Inn Road (near Fleet Street) to new offices in Wapping.

Question: What printing process for The Times was replaced by computers in 1982?
Ans: hot-metal Linotype printing process

Here is a question about this article: Holy Roman Empire central power had begun to decline following years of imperial adventures in Italian lands, often ceding hegemony in Western Europe to France, which had long since centralized power. France began an aggressive policy of expanding eastward, first to the rivers Rhone and Meuse, and when those borders were reached, aiming for the Rhine. In 1299, the French proposed a marriage alliance between Philip IV of France's sister Blanche and Albert I of Germany's son Rudolf, with Alsace to be the dowry; however, the deal never came off. In 1307, the town of Belfort was first chartered by the Counts of Montbeliard. During the next century, France was to be militarily shattered by the Hundred Years' War, which prevented for a time any further tendencies in this direction. After the conclusion of the war, France was again free to pursue its desire to reach the Rhine and in 1444 a French army appeared in Lorraine and Alsace. It took up winter quarters, demanded the submission of Metz and Strasbourg and launched an attack on Basel.
What is the answer to this question: What were the names of the first two rivers France aggressively went to while expanding eastward?
****
So... Rhone and Meuse

Article: This is a consequence of Lorentz reciprocity. For an antenna element not connected to anything (open circuited) one can write . But for an element which is short circuited, a current is generated across that short but no voltage is allowed, so the corresponding . This is the case, for instance, with the so-called parasitic elements of a Yagi-Uda antenna where the solid rod can be viewed as a dipole antenna shorted across its feedpoint. Parasitic elements are unpowered elements that absorb and reradiate RF energy according to the induced current calculated using such a system of equations.

Question: What element absorbs and reradiate RF-energy?
Ans:
Parasitic
