Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. The Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Copernican heliocentrism is often regarded[by whom?] as the launching point to modern astronomy and the Scientific Revolution.
Heliocentric model from Nicolaus Copernicus' De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres)
Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so late in his life by his pupil Rheticus. Copernicus's challenge was to present a practical alternative to the Ptolemaic model by more elegantly and accurately determining the length of a solar year while preserving the metaphysical implications of a mathematically ordered cosmos. Thus, his heliocentric model retained several of the Ptolemaic elements, causing inaccuracies such as the planets' circular orbits, epicycles, and uniform speeds,[1] while at the same time introducing such innovative ideas as:-
The Earth is one of several planets revolving around a stationary sun in a determined order.
The Earth has three motions: daily rotation, annual revolution, and annual tilting of its axis.
Retrograde motion of the planets is explained by the Earth's motion.
The distance from the Earth to the Sun is small compared to the distance from the Sun to the stars.

Explanation:
Even though global trade has fluctuated over the years, it has also rapidly increased. However, the structure and pattern of trade vary significantly by-products and regions. Undoubtedly, trade has come with both benefits and daunting challenges to countries involved, especially in African nations, where primary and intermediate merchandise formed a substantial share of exports. Because advanced and newly industrialized economies have better technology and know-how, manufacturing industries, access to finance, and market than Africa, they have a greater market proportion in the world trade. Arguably, African countries have been left in the cold as they struggle to compete with advanced economies. As presented in this chapter, Africa has been struggling to be relevant in the world market. However, its global share of merchandise trade has reduced over the decades. This is partly because the continent has concentrated on the exportation of few primary commodities (i.e., mineral fuels, iron ores, gold, cocoa beans) with volatile prices and demand in the global markets. The frequent global oil crunch other raw products are a wake-up call for a rapid industrialization and diversification for competitiveness in Africa. The World Trade Organization (WTO) has to ensure that defensive trade remedies should not be the next frontier of protectionism. Finally, for trade, growth, and development to be stimulated, African countries should urgently open their markets to expand intra-African trade.
USA intervened in Korea and Vietnam as war efforts and in Greece and Turkey as coups.
Explanation:
In Turkey the US government aided a coup by the military to overthrow the government which in turn led to a regressive government to be placed in there.
A similar thing happened in Greece when a socialist party was elected into the Country with affiliations or alleged ones with the Soviet Union.
Korea was invaded by the USA in support of the south during the Korean war so as to stop the communist North from taking over all of the Korea under the influence of USSR.
Similar thing happened in Vietnam but it was not successful and Vietnam did fall to the communist army after US departure.
