Humans often use language, the most powerful symbol, to take part in cultural  transmission —that is, to share what they know, think, and experience.

Explanation:

Language is one of the most important aspects of human life and experience. It can be expressed in many forms, orally, written, signally, tactile, etc. and it always uses a set of various symbols in different forms.

Language is one of the main qualities of humans as intelligent species, and its sharing, transmission, and development are in charge of developing civilizations. Thanks to the language, people could finally share and develop their ideas, values, and knowledge. With this, they became more intelligent and progressed, managing to increase the improvement of the society.

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.
