An alloy is a mixture of either pure or fairly pure chemical elements, which forms an impure substance (admixture) that retains the characteristics of a metal. An alloy is distinct from an impure metal, such as wrought iron, in that, with an alloy, the added impurities are usually desirable and will typically have some useful benefit. Alloys are made by mixing two or more elements; at least one of which being a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy. The other constituents may or may not be metals but, when mixed with the molten base, they will be soluble, dissolving into the mixture.
What other metal is impure like alloy?
****
The answer: wrought iron

The city is colloquially known as Chilangolandia after the locals' nickname chilangos. Chilango is used pejoratively by people living outside Mexico City to "connote a loud, arrogant, ill-mannered, loutish person". For their part those living in Mexico City designate insultingly those who live elsewhere as living in la provincia ("the provinces", the periphery) and many proudly embrace the term chilango. Residents of Mexico City are more recently called defenos (deriving from the postal abbreviation of the Federal District in Spanish: D.F., which is read "De-Efe"). They are formally called capitalinos (in reference to the city being the capital of the country), but "[p]erhaps because capitalino is the more polite, specific, and correct word, it is almost never utilized".
What do Mexicans call Mexico City?
****
The answer: Chilangolandia

The problem: Answer a question about this article:
In the Treaty of Paris after the Revolution, the British had ceded the lands between the Appalachian Mountains and the Mississippi River to the United States, without consulting the Shawnee, Cherokee, Choctaw and other smaller tribes who lived there. Because many of the tribes had fought as allies of the British, the United States compelled tribal leaders to sign away lands in postwar treaties, and began dividing these lands for settlement. This provoked a war in the Northwest Territory in which the U.S. forces performed poorly; the Battle of the Wabash in 1791 was the most severe defeat ever suffered by the United States at the hands of American Indians. President Washington dispatched a newly trained army to the region, which decisively defeated the Indian confederacy at the Battle of Fallen Timbers in 1794.
What three major tribes occupied these formerly British territories?
****
The answer: Shawnee, Cherokee, Choctaw

The problem: Answer a question about this article:
Qianlong's reign saw the launch of several ambitious cultural projects, including the compilation of the Siku Quanshu, or Complete Repository of the Four Branches of Literature. With a total of over 3,400 books, 79,000 chapters, and 36,304 volumes, the Siku Quanshu is the largest collection of books in Chinese history. Nevertheless, Qianlong used Literary Inquisition to silence opposition. The accusation of individuals began with the emperor's own interpretation of the true meaning of the corresponding words. If the emperor decided these were derogatory or cynical towards the dynasty, persecution would begin. Literary inquisition began with isolated cases at the time of Shunzhi and Kangxi, but became a pattern under Qianlong's rule, during which there were 53 cases of literary persecution.
How many volumes were in the Siku Quanshu?
****
The answer:
36,304 volumes
