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: amygdala
Explanation:
The amygdala is located in the temporal lobe, which plays an important role in the nervous system. The amygdala's function is to control emotions; through the amygdala, the person can react physiologically or behaviorally to the situation that causes the emotion.
Likewise, it is considered that the amygdala is the one that keeps us alert to the different stimuli that can cause harm to us.

Answer:
Bisexual
Explanation:
The term bisexual refers to people who are romantically or sexually attracted to both males and females. This means that they have no particular sexual preference on one or the others and has erotic interests in both genders.
In this example, Alastair is <u>currently in a relationship with a woman but he has also dated men in the past</u>. He has no particular sexual preference and has <u>erotic interests in both men and wome</u>n.
Thus, we can say that Alastair is most likely bisexual
Answer: Tan builds a central idea of her story analyzing the type of questions and how they can affect students' ability to write well.
Explanation:
Tan analyses the type of questions and exercises present in the test, and quoting her mother, she affirms that are too easy.
In the given example: "Even though Tom was <u>foolish</u>, Mary thought he was <u>ridiculous</u>." The adjectives <u>foolish</u> and <u>ridiculous</u> can be replaced by any other. In that way, Tan asserts that this kind of tests might affect students' ability to write well because they aren't putting real effort on solving them.
