Answer:
(B) can also be interpreted as shifts of their respective marginal cost curves.
Explanation:
Marginal Cost represents the total cost increase that occurs when the quantity of goods produced is increased by one unit (or the total cost reduction after the reduction by one unit in the quantity produced). By the Law of Decreasing Marginal Income, Marginal Costs are increasing as more units of good are produced because, from a certain point, to get one more unit produced it is necessary to add more and more units of the productive factor.
With this, we can conclude that the resulting changes in supply curves for coal miners and electricity producers in relation to increased demand for these goods can also be interpreted as changes in their respective marginal cost curves.
Answer:B) naturalistic observation
Explanation:
Naturalistic observation occurs when a researcher observes the participants in their natural environment without manipulating the experiment. This is done when doing a laboratory experiments will be unreasonable for the research question. Participants may not behave normal when they are in a constrained environment where they know they are being watched , they may even alter their behaviour to suit what is expected.
In their natural environment people behaves normal especially when they know they are not being watched , Which will give Lilly a perfect presentation of how students normally behave in class during a test.
