Randolf is walking down the street of his hometown, after being away for several years, when he smells the scent of freshly baked pie coming from a local baker. He suddenly has vivid memories of walking down this street as a child, holding both of his parents' hands, and swinging between them, feeling relaxed and happy. This is because the sense of smell projects directly to the memories. which is responsible for Which of the following is not a disadvantage of PET scanning? A) An alternative diagnostic tool is fMRI. B) It is unable to pinpoint events in time. C) There is a low level of detail. D) There is radiation exposure.

Limbic System ; Emotion A)

Explanation:

Ok so aparently there seem to be two questions in this statement,

The answer to the first question is that the sense of smell projects directly to the limbic system. The limbic system is a set of structures that are located in the brain and handle everything that relates with emotion and memories. Which is why the smell made Randolf have that memory which then caused an emotional response.

The answer to the second question is that the answer that is not a disadvantage of PET scanning is that an alternative diagnostic tool is fMRI. Mainly because alternatives are always a good thing since they provide validity.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
