B. The work once done by skilled workers was now done by machines and unskilled workers.
<span>
Mass-production techniques and technology called for setting up huge factories with large work force. It created a lot of jobs but due to the division of labor, the skill requirements for a particular job were quite monotonous. Skilled workers were replaced by machines and unskilled machine operators that could perform a single task instead of an array of tasks.

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.
Answer:
The Bill of Rights is the first 10 amendments to the U.S. Constitution. These amendments guarantee essential rights and civil liberties, such as the freedom of religion, the right to free speech, the right to bear arms, trial by jury, and more, as well as reserving rights to the people and the states.
Explanation:
The amendments, known as the Bill of Rights, were designed to protect the basic rights of U.S. citizens, guaranteeing the freedom of speech, press, assembly, and exercise of religion; the right to fair legal procedure and to bear arms; and that powers not delegated to the federal government were reserved for the states .
Answer:
He is having difficulty in the area of 4) pragmatics.
Explanation:
The term pragmatics was coined in the 1930s by psychologist Charles Morris. This subfield of linguistics studies the social language skills that we use in our interactions, how we produce and understand meanings through language while communicating with others. That means pragmatics analyzes not only what we say, but also the way we say it, our body language, facial expressions, gestures, and how appropriately we interact. It is this part that concerns Cade. He is able to express himself accurately, but still struggles with interacting with others in context. His difficulty, therefore, concerns pragmatics.
