Article: Tucson's primary electrical power source is a coal and natural gas power-plant managed by Tucson Electric Power that is situated within the city limits on the south-western boundary of Davis-Monthan Air-force base adjacent to Interstate-10. The air pollution generated has raised some concerns as the Sundt operating station has been online since 1962 as is exempt from many pollution standards and controls due to its age. Solar has been gaining ground in Tucson with its ideal over 300 days of sunshine climate. Federal, state, and even local utility credits and incentives have also enticed residents to equip homes with solar systems. Davis-Monthan AFB has a 3.3 Megawatt (MW) ground-mounted solar photovoltaic (PV) array and a 2.7 MW rooftop-mounted PV array, both of which are located in the Base Housing area. The base will soon have the largest solar-generating capacity in the United States Department of Defense after awarding a contract on September 10, 2010, to SunEdison to construct a 14.5 MW PV field on the northwestern side of the base.

Question: What does Tucson's main power plant use for fuel?
Ans: coal and natural gas

Article: In the next century which is the beginning of the Classical period, it was considered that beauty in visible things as in everything else, consisted of symmetry and proportions. The artists tried also to represent motion in a specific moment (Myron), which may be considered as the reappearance of the dormant Minoan element. Anatomy and geometry are fused in one, and each does something to the other. The Greek sculptors tried to clarify it by looking for mathematical proportions, just as they sought some reality behind appearances. Polykleitos in his Canon wrote that beauty consists in the proportion not of the elements (materials), but of the parts, that is the interrelation of parts with one another and with the whole. It seems that he was influenced by the theories of Pythagoras. The famous Apollo of Mantua and its variants are early forms of the Apollo Citharoedus statue type, in which the god holds the cithara in his left arm. The type is represented by neo-Attic Imperial Roman copies of the late 1st or early 2nd century, modelled upon a supposed Greek bronze original made in the second quarter of the 5th century BCE, in a style similar to works of Polykleitos but more archaic. The Apollo held the cythara against his extended left arm, of which in the Louvre example, a fragment of one twisting scrolling horn upright remains against his biceps.

Question: What type of art is modeled after a supposed Greek bronze original made in the second quarter of the 5th Century BCE.
Ans: neo-Attic Imperial Roman copies of the late 1st or early 2nd century

Article: Because exposure to media has increased over the past decade, adolescents' utilization of computers, cell phones, stereos and televisions to gain access to various mediums of popular culture has also increased. Almost all American households have at least one television, more than three-quarters of all adolescents' homes have access to the Internet, and more than 90% of American adolescents use the Internet at least occasionally. As a result of the amount of time adolescents spend using these devices, their total media exposure is high. In the last decade, the amount of time that adolescents spend on the computer has greatly increased. Online activities with the highest rates of use among adolescents are video games (78% of adolescents), email (73%), instant messaging (68%), social networking sites (65%), news sources (63%), music (59%), and videos (57%).

Question: What online activity has the largest number of reported adolescent particpation?

Article: The papacy further refined the practice in the Mass in the Late Middle Ages, holding that the clergy alone was allowed to partake of the wine in the Eucharist. This further distanced the secular laity from the clergy. The laity continued the practices of pilgrimages, veneration of relics, and belief in the power of the Devil. Mystics such as Meister Eckhart (d. 1327) and Thomas a Kempis (d. 1471) wrote works that taught the laity to focus on their inner spiritual life, which laid the groundwork for the Protestant Reformation. Besides mysticism, belief in witches and witchcraft became widespread, and by the late 15th century the Church had begun to lend credence to populist fears of witchcraft with its condemnation of witches in 1484 and the publication in 1486 of the Malleus Maleficarum, the most popular handbook for witch-hunters.

Question: In the Late Middle Ages, who was allowed to drink wine at Mass?
Ans:
the clergy
