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.
One obvious similarity between both the Northeast and the Southeast is the Atlantic ports for international trade. Both areas contain parts of the Appalachian Trail. Both areas have mountains. They each have their own mannerisms and cultures. Interstate 95 traverses both the Northeast and the Southeast. Both do farming but in different quantities. Both have severe weather patterns with the Northeast being hit by both hurricanes and storms called Nor'easters. The Southeast it often hit by hurricanes. Winter storms are hardly Both suffered great losses from the Civil War and are very proud of their military heritage.
Answer:
True in most cases
Explanation:
This fact established can also be compared to a successful father or head male, if a father is successful, then there is tendency that the children will have that influence from there father to become successful ,so everything boils down to the father compared to the mother. Regardless of the gender of the children .So can be said about the criminality of the fathers can be of an influence to the children but note there is a possibility it might not happen( the children Also becoming a criminal), but in most true cases it happens but it all depends on the father and the mother generally.
Answer:
Kennedy played a role in revolutionizing American politics. Television began to have a real impact on voters and long, drawn-out election campaigns became the norm, and style became an essential complement to substance.
Explanation:
This is a big impact since it started the change that makes tv what it is today and changed polotics forever.
Self control is my best guess
Hope I helped-beanz :)
