Problem: Many ancient civilizations alloyed metals for purely aesthetic purposes. In ancient Egypt and Mycenae, gold was often alloyed with copper to produce red-gold, or iron to produce a bright burgundy-gold. Gold was often found alloyed with silver or other metals to produce various types of colored gold. These metals were also used to strengthen each other, for more practical purposes. Copper was often added to silver to make sterling silver, increasing its strength for use in dishes, silverware, and other practical items. Quite often, precious metals were alloyed with less valuable substances as a means to deceive buyers. Around 250 BC, Archimedes was commissioned by the king to find a way to check the purity of the gold in a crown, leading to the famous bath-house shouting of "Eureka!" upon the discovery of Archimedes' principle.
Ancient civilizations often alloyed metals for what reason?
The answer is the following: purely aesthetic purposes

Problem: The Bronx is referred to, both legally and colloquially, with a definite article, as the Bronx. (The County of Bronx, unlike the coextensive Borough of the Bronx, does not place the immediately before Bronx in formal references, nor does the United States Postal Service in its database of Bronx addresses.) The name for this region, apparently after the Bronx River, first appeared in the Annexed District of the Bronx created in 1874 out of part of Westchester County and was continued in the Borough of the Bronx, which included a larger annexation from Westchester County in 1898. The use of the definite article is attributed to the style of referring to rivers. Another explanation for the use of the definite article in the borough's name is that the original form of the name was a possessive or collective one referring to the family, as in visiting The Broncks, The Bronck's or The Broncks'.
What is the Bronx's borough name?
The answer is the following: Borough of the Bronx

Problem: Russell's ministry, though Whig, was not favoured by the Queen. She found particularly offensive the Foreign Secretary, Lord Palmerston, who often acted without consulting the Cabinet, the Prime Minister, or the Queen. Victoria complained to Russell that Palmerston sent official dispatches to foreign leaders without her knowledge, but Palmerston was retained in office and continued to act on his own initiative, despite her repeated remonstrances. It was only in 1851 that Palmerston was removed after he announced the British government's approval of President Louis-Napoleon Bonaparte's coup in France without consulting the Prime Minister. The following year, President Bonaparte was declared Emperor Napoleon III, by which time Russell's administration had been replaced by a short-lived minority government led by Lord Derby.
What replaced Russell's administration?
The answer is the following: a short-lived minority government led by Lord Derby

Problem: Jesuit missionary Eusebio Francisco Kino visited the Santa Cruz River valley in 1692, and founded the Mission San Xavier del Bac in 1700 about 7 mi (11 km) upstream from the site of the settlement of Tucson. A separate Convento settlement was founded downstream along the Santa Cruz River, near the base of what is now "A" mountain. Hugo O'Conor, the founding father of the city of Tucson, Arizona authorized the construction of a military fort in that location, Presidio San Agustín del Tucsón, on August 20, 1775 (near the present downtown Pima County Courthouse). During the Spanish period of the presidio, attacks such as the Second Battle of Tucson were repeatedly mounted by Apaches. Eventually the town came to be called "Tucson" and became a part of Sonora after Mexico gained independence from Spain in 1821.
Which missionary came to the Santa Cruz River area in 1692?
The answer is the following:
Eusebio Francisco Kino
