Explanation
Nicolás Copernicus (1473 - 1543) was an astronomer of Prussian origin who stands out for being the one who first formulated the heliocentric theory of the solar system. It is necessary to remember that during the medieval period (5th century BC - 15th century AD) science was stagnant due to the rise of the Christian religion in Europe. Later, with the arrival of the Renaissance and the Enlightenment, the sciences took on greater importance than religion and there were great technological, scientific, mathematical, geographical advances and in general in all areas of science. During this time the theory that had been accepted throughout the world was the Geocentric one that affirmed that the earth was the center of the solar system and that the other planets orbited around it. For his part, Nicolas Copernicus spent a long time studying to argue the Heliocentric theory, in which he rejected the claim that the planet Earth was the center of the solar system to propose that the sun was the center of the solar system and that the planets orbited around it. Copernicus's theory was unveiled the same year of his death
1543, when he published his book the Revolution of the Celestial Spheres, in which he exposed his model of the solar system and explained his theory in detail. Therefore, the correct answer is In 1543, Nicolaus Copernicus published On the Revolution of the Celestial Spheres, which said the universe was heliocentric.
By their nature and moto, the Non-aligned Movements did not support either the Democratic Party or the Communist Party during the Greek Civil War of 1949.
<h3>What is the role of Unaligned Movements?</h3>
The role of the Non-aligned Movements during the Greek Civil War of 1949 was to ensure that governments everywhere practiced policies and practices of cooperation for the mutual benefit of all those involved in the Greek conflict without supporting either party.
This non-alignment with the two dominant parties eventually led to the defeat of the communist party by the Greek Army.
Thus, the Unaligned movements believed strongly that neither the communist-dominated left-wing resistance nor the anti-communist resistance forces should receive international support during the Greek Civil War.

Considering a point of view it is fair to say that Mr. Ellsberg attacked democracy itself by disclosing the private study. From Ellsberg's view he took it upon himself to inform the public about a crucial issue namely, that the study showed, in his opinion, that the American government had been lying for years about the progress of the war The Pentagon Papers leak may have compromised national security, but only by showing the rest of the world that the US was incapable of keeping its secrets.
Extent to which government should be allowed to have secrecy:
Governmental secrecy has a peculiar quality that results from the lack of a known mechanism for limiting its exercise to specific areas on which reasonable people can agree.
The cost of secrecy extends beyond the spread of mistrust that the government is abusing the public's confidence. It also serves as a means of halting the national discourse in which citizens prepare themselves for important decisions that may require significant sacrifice. The Pentagon Papers serve as the best example of this.
