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 facial feedback effect
Explanation:
The facial feedback effect refers to the impact of facial expressions on the emotional state of the individual. Also, forced expressions tend to make people more uncomfortable and unhappy even if they are being forced to smile like on social gatherings. Here, it is said that 'most recent participants reported feeling more happy than sad after rubberbands secured to the sides of their faces were stretched over the tops of their heads'. Hence, this is clearly the facial feedback effect as it highlights the impact of facial expressions on the emotional state of the participants.
To protect Venice (a city in Italy) from over-tourism, the number of tourists allowed should be 55,000 per day.
Venice is a beautiful city in Italy that attracts a great deal of tourists. Some 20 million people flood Venice every year. on its busiest days, the tourist number increases to 120,000 which is almost double the population residing there.
Venice is in the mood to reduce tourist entry due to the fact that many people come on cruises, stay for a few hours, and leave, providing no economic benefit.
The visitors who do stay for a night or two may also contribute to Venice's problems. Due to high property prices, owners are converting family homes and low-income rentals into lucrative holiday rentals. As a result, housing is becoming increasingly expensive, and only the very wealthy can afford to live here.
The very well solution is that the tourist count should be limited to just as the population count who are the permanent residents i.e. 55,000.
