In 144 BC Emperor Jing abolished private minting in favor of central-government and commandery-level minting; he also introduced a new coin. Emperor Wu introduced another in 120 BC, but a year later he abandoned the ban liangs entirely in favor of the wuzhu (五銖) coin, weighing 3.2 g (0.11 oz). The wuzhu became China's standard coin until the Tang dynasty (618–907 AD). Its use was interrupted briefly by several new currencies introduced during Wang Mang's regime until it was reinstated in 40 AD by Emperor Guangwu.
Who introduced new coinage in the year of 120 BC?
Emperor Wu


Input: Indigenous peoples of the Americas
Genetic studies of mitochondrial DNA (mtDNA) of Amerindians and some Siberian and Central Asian peoples also revealed that the gene pool of the Turkic-speaking peoples of Siberia such as Altaians, Khakas, Shors and Soyots, living between the Altai and Lake Baikal along the Sayan mountains, are genetically closest to Amerindians.[citation needed] This view is shared by other researchers who argue that "the ancestors of the American Indians were the first to separate from the great Asian population in the Middle Paleolithic. 2012 research found evidence for a recent common ancestry between Native Americans and indigenous Altaians based on mitochondrial DNA and Y-Chromosome analysis. The paternal lineages of Altaians mostly belong to the subclades of haplogroup P-M45 (xR1a 38-93%; xQ1a 4-32%).

What DNA analysis indicated the common ancestry of the Native Americans?
Output: mitochondrial DNA and Y-Chromosome


Input: Article: Nasser's nomination for the post and the new constitution were put to public referendum on 23 June and each was approved by an overwhelming majority. A 350-member National Assembly was established, elections for which were held in July 1957. Nasser had ultimate approval over all the candidates. The constitution granted women's suffrage, prohibited gender-based discrimination, and entailed special protection for women in the workplace. Coinciding with the new constitution and Nasser's presidency, the RCC dissolved itself and its members resigned their military commissions as part of the transition to civilian rule. During the deliberations surrounding the establishment of a new government, Nasser began a process of sidelining his rivals among the original Free Officers, while elevating his closest allies to high-ranking positions in the cabinet.

Now answer this question: Among the original Free Officers, what did Nasser do to his opponents? 

Output: sidelining


Article: The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.

Question: What shape were the A and B buttons on the earliest Famicom controllers?
Ans: square


Here is a question about this article: Bitumen was the nemesis of many artists during the 19th century. Although widely used for a time, it ultimately proved unstable for use in oil painting, especially when mixed with the most common diluents, such as linseed oil, varnish and turpentine. Unless thoroughly diluted, bitumen never fully solidifies and will in time corrupt the other pigments with which it comes into contact. The use of bitumen as a glaze to set in shadow or mixed with other colors to render a darker tone resulted in the eventual deterioration of many paintings, for instance those of Delacroix. Perhaps the most famous example of the destructiveness of bitumen is Théodore Géricault's Raft of the Medusa (1818–1819), where his use of bitumen caused the brilliant colors to degenerate into dark greens and blacks and the paint and canvas to buckle.
What is the answer to this question: What pigment did 19th century artists use that was deemed unfavorably?
****
So... Bitumen


Article: Devise Minority Party Strategies. The minority leader, in consultation with other party colleagues, has a range of strategic options that he or she can employ to advance minority party objectives. The options selected depend on a wide range of circumstances, such as the visibility or significance of the issue and the degree of cohesion within the majority party. For instance, a majority party riven by internal dissension, as occurred during the early 1900s when Progressive and "regular" Republicans were at loggerheads, may provide the minority leader with greater opportunities to achieve his or her priorities than if the majority party exhibited high degrees of party cohesion. Among the variable strategies available to the minority party, which can vary from bill to bill and be used in combination or at different stages of the lawmaking process, are the following:

Question: Does minority leader always employ same strategy for party objectives?
Ans:
options selected depend on a wide range of circumstances
