Betsy and Tina, both third-graders in the same classroom, are assigned by their teacher to different groups that will compete in a spelling bee. Betsy and Tina each believe that their own group is composed of the better spellers.
The girls' beliefs best illustrate:

A) the just-world phenomenon.
B) ingroup bias.
C) the fundamental attribution error.
D) authoritarianism.

B) ingroup bias.

Explanation:

In psychology, the term ingroup bias refers to the tendency we have to favor the group we belong to or to think our group is better than the group other people belong to (the outgroup).

In this example, Betsy and Tina are assigned to different groups that will compete in a spelling bee. Both Betsy and Tina believe that their own group is composed of the better spellers. We can see that they are favoring the group they belong (or the ingroup). Therefore, their beliefs best illustrate the ingroup bias.

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.

if im not mistaken its a. collective emotional arousal
