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.

The correct answer is Scotland
British and other settlers
Europeans form an immigration mass to the United States. This immigration began with the colonization of the country in the seventeenth century and lasted until the mid-1970s. The first English colony began its record of success in North America in Jamestown, Virginia, in 1607.
Bronze is an alloy of copper and tin
The correct answer is option A. When a shore parallel band is forming in the center of a lake, convergence is happening at the surface over the center of the lake.
Shore-Parallel Bands form when winds are light and heat from the lake causes rising air, drawing in air from both sides and forming one long band of lake effect snow; areas beneath such a band can receive enormous amounts of snow, while regions only a few miles away will receive very little, if any, snow.
Air is forced upward when it crosses the downwind shoreline due to friction with the earth surface, which slows down the wind and causes convergence close to the beach. The snowiest areas are those closest to and inside this convergence zone.
