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:
First team wedge
Explanation:
The first team wedge is a
basic formation for where the interval between
People in the wedge formation
is normally 10 meters. The
wedge expands and contracts
depending on the terrain.
When rough terrain, poor
visibility, or other factors make
control of the wedge difficult,
fire teams modify the wedge.
The normal interval is reduced
so that all team members can still see their team leader and the team
leaders can still their squad leader.

Answer:
People may be at risk of developing anxiety or depression after experiencing a traumatic event or a natural disaster like a bushfire, flood, cyclone or earthquake.
Communities and individuals affected by a disaster can experience a range of thoughts, feelings and behaviours that can be intense, confusing and frightening. These are common reactions to an extraordinary situation. Fear, for example, is an important and normal reaction that helps activate our body and mind to make decisions to protect our own life and the lives of loved ones, friends and neighbours. It is also normal for the memory of intense fear to stay with us.
Following a traumatic event or disaster, many people deal with memories and ongoing feelings by drawing on their own strengths, as well as the support of others, and will gradually rebuild their lives and achieve a sense of wellbeing again.
However, it is common that some people struggle to deal with feelings and thoughts that may follow such an event. It's important to know the difference between a common reaction to a stressful or traumatic event and signs that indicate you should seek additional support.
Depending on the country and type of government, this is true. It is called the Right Of Revolution, and is commonly used in democracy.
