Explanation:

The prince of Portugal, preferably known as Infante D. Henry, was not only a prince, but also the patron of Portuguese explorers. Prince Henry has sent numerous trips to the west coast of Africa, which should create maps of the area needed to defeat Muslims, facilitate the spread of Christianity, and establish maritime trade routes. Portuguese ships were able to sail to Madeira and were the first to sail to the Gambia River because of their sponsorship. Portugal's influence in the Great Age of Discovery was also attributed to him.

He is known as Prince Henry the Navigator; for he was a monarch who had many interests in navigation. This interest has accompanied him since his youth and influenced him to start a school for sailors in Portugal.

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.
