Answer: The Monroe Doctrine was a United States policy that was introduced on December 2, 1823.The Monroe Doctrine became the cornerstone of America's
foreign policy for almost 100 years. It also enabled the
nations of Latin America to pursue policies free from the European influences. However, it has also created some problems with certain Latin American countries who feel that America's self-appointed "big brother" status is unwarranted.
Answer:
B: Parts could be used for different machines
Explanation:
Hello. This question is incomplete. The full question is:
"Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars. Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?
(A) The cost of oil has fallen dramatically. (B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment. (C) Technological changes have increased the efficiency of oil-fired power plants. (D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants. (E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable."
Answer:
(C) Technological changes have increased the efficiency of oil-fired power plants.
Explanation:
Economic viability is able to reveal the degree of acceptance of consumers in relation to a specific product. This viability is important to understand how the product will be received in the market and how profitable or not it can be for those who produce it.
Economic viability is usually greater when the cost and benefit ratio of the product or service is favorable, however this is not always the case.
Regarding the use of solar energy, although technological changes have made the installation and equipment of this type of energy more cost-effective, these technological changes have also increased the efficiency of oil plants. As a result, the economic viability of solar energy has declined.

<span> </span><span>The Arizona-Sonora Border:
Line, Region, Magnet, and Filter</span><span>.<span> . . Belonging truly to neither nation, it serves as a kind of cultural buffer zone for both, cultivating its own culture and traditions. Like other borders, it both attracts and repels. Like them, it is both barrier and filter. It is above all a stimulating cultural environment. . . .</span>--James S. Griffith
The Arizona Sonora border was established as a result of the Gadsden Purchase of 1853. It runs through desert and mountain country, from the western Chihuahuan Desert by New Mexico through a zone of grassland and oak-covered hills to the classic Sonoran Desert west of Nogales. The land gets more and more arid as one travels west, and the western third of the border is essentially devoid of human habitation. It is this stretch of the border, once a major road to the Colorado River, that has earned and kept the title El Camino del Diablo, "The Devil's Highway."</span>
