Elizabeth has invited Professor Valdez and her boss, Mr. Sapienza, to coffee on a couple of occasions, but both have turned down her invitation. Elizabeth would really like to have these two people as friends, but cannot seem to make that happen. Which characteristic of friendships does Elizabeth apparently not understand

Friends are mostly peer or per group

Explanation:

Peer group or peer is the group of people that contain the individual who have almost same age as the person along with similar interest,background, work social status. These members of peer group can influence and impact behavior of each other .

According to the question,Elizabeth does not understand the concept of friend are mostly peer as they have similar age and interest. Thus, boss and professor did not accept invitation for coffee of  Elizabeth as they are not her peer. They do not belong to same age group and social background.  

answer; /// (c) i do believe that the correct answer is ; an unstated guarantee that goods will be to the consumer's liking;

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.
