Cities and towns grew rapidly between 1000 and 1300. one reason for their rapid growth was that improved agricultural practices (the agricultural revolution) made more food available. according to your text, a major cause for urban (city) population growth was .

major cause of increase population in the town is short and long distance trade

Explanation:

major cause of increase population in the town is short and long distance trade

Around 1000 to 1300, there s tremendous increase in cities and towns population. One primary reason for this sudden growth was availability of more food through enhanced farming practices . According to text, long and short distance trade was indeed a leading cause of urban population expansion.

industry had made the u.s. the richest nation in the world at this time. the second industrial revolution caused growth in industry and transportation, which allowed increased trade between nations.

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.
