answers:
a.
egocentrism
b.
conservation
c.
object permanence
d.
transformation
c

c) Object permanence

Explanation:

Jean Piaget developed a theory about cognitive development according to which people go through different stages on learning since the day they are born and until adulthood.

Piaget's states that cognitive development goes through different stages and in each one of them the brain acquires new abilities and capacities.

Object permanence refers to the ability to understand that objects still exist even if they are no longer visible. At first, little kids don't understand this and they think that when an object is out of sight it doesn't exist anymore (and also that's why they love to play peek-a-boo for example), however, as they grow older they understand that objects continue existing even when they are not in sight.

In this example, Jonathan is eight-months-old and he is left by his mother at the baby-sitter's place. The minute he could not see her, he started to cry. Because of Jonathan's age and his reaction we can say that he hasn't developed the concept of "object permanence" yet and he's crying because he thinks his mom just disappeared.

Thus, the concept that would explain Jonathan's behavior would be "object permanence"

depends.

explanation:

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.
