Answer:
I think true
Explanation:
this is a tough question because composition can occur and only benefit one person. competition can also just occur between two people.
The answer for this question is: Decrease in environmental impact
In order for people in China to achieve middle-class status, they need to open up a lot of business to compete in the market.
This result in a lot of waste excreted to the environment during the production process which cause a lot of environmental impact in that country.
Answer:
B. Words stored in echoic memory will last for 3 to 4 seconds, so you can still recall her words.
Explanation:
We have different types of memory, one of those types of memory is echoic memory.
This memory is a type of sensory memory that register sounds, when we first hear something, the sound is stored in this memory so it can be processed. The stimuli last about 3 to 4 seconds in the echoic memory (that's why sometimes we can hear something after it was said even if we're not paying attention)
In this example, your mom is lecturing you and you lose concentration, when she asks you if you're listening and you are able to repeat the last few things she said. We can see that this is an effect of the echoic memory, that <u>has stored the last 3-4 seconds of your mom's lecture and you can repeat this even if you were not paying attention. </u>

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.
