Answer:
The Soviet Union (Russia)
Explanation:
This was because because both the United States and Russia were throwing threat of a nuclear warfare, with no actual actions of the threats were done.
All of these strategies involve using selective optimization with compensation.
Answer: Option D
<u>Explanation:</u>
Selective optimization with compensation speaks about how to improve health and the well being of the older adults. This gives importance to aging in a successful way.
All the strategies which are given in the options speak about the selective optimization with compensation. She thinks that cleaning is the most important for her so cuts down on other activities and she does not want to totally depend upon the cleaning services. So all these talk about selective optimization.
Answer:
Isolation
Explanation:
WAY back in the day, President Washington warned the U.S. in his farewell address not to become entangled with foreign nations since France was meddling in their politics. This established an impromptu policy of isolationism, where the U.S. would not get involved in any foreign conflicts, or entangle themselves in the political disputes of other nations. This carried through to WWI, until the Germans repeatedly sunk civilian vessels and killed innocent Americans. They still remained isolationists post WWI with the League of Nations, not entering into it.
When WWII came around, the attack on Pearl Harbor was a direct attack on America, and they couldn't remain isolated any longer. After the war, they joined the United Nations, and did end up entangling themselves in many nations in order to stop the spread of communism.
I believe the answer is C
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.
