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.
They believed that a strong national government would cause the same problems the strong central leaders of England did. They didn't want a small tight knit group receiving all or most of the power. They didn't want to states to lose power so most of the power was given to them. A strong national government was viewed as dangerous
Answer:
It means that your classmate is to review your article. They sould read and correct spelling errors or punctuation ( but this all depends on their levels of being able to do these tasks). But the main goal is to read and give you feedback.
Explanation:
Fruits ripen after being picked by spraying or injecting the fruits with hormones.
Ripening is only hastened in climacteric fruits (ie.apples, pears, tomatoes). The fruits continue to ripen mostly due to hormone named ethylene gas.
ANSWER: D) by spraying or injecting the fruits with hormones.
Hope this helps! :)
1. Trade imbalance with Great Britain, which led to Opium imports into China, which the Chinese tried to ban but failed. This led to the Opium Wars.
2. An outcome of the Opium wars was British victory leading to the Chinese signing unequal treaties, opening trade, giving land to the British and forcing the Chinese to pay for the war.
3. The Europeans established 'spheres of influence' in certain territories of China, leading to the Chinese fighting back, to gain independence.
