According to Peter Singer's theory, we (the affluent) ought to give to the needy until we reach the level of marginal utility-which means that in giving the appropriate amount, we would reduce ourselves to very near the material circumstances of:

a. a middle-class American.
b. a Bengali refugee.
c. an immigrant from working-class Britain.
d. the average citizen of the United Arab Emirates.

b. a Bengali refugee

Explanation:

Peter Albert David Singer AC was a popular Australian moral philosopher. He was well known for his works in Bioethics.

He proposed a theory which states that:

‘We(the affluent) ought to give to the needy until we reach the level of marginal utility-which means that in giving the appropriate amount, we would reduce ourselves to very near the material circumstances of a Bengali refugee’. This simply tells us that we ought to save the lives of strangers when we can do so at relatively little cost to ourselves.

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.
