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.

Answer:
Correct answer is C. East Germany adopted a communist government while West Germany maintained Democratic influence.
Explanation:
Option C is the only correct answer as after WW2 Germany was divided into Eastern part, which was under influence of Soviet Union and Western part which was under influence of United States, Britain and France.
A therefore cannot be correct as both options are not correct. East Germany wasn't liberal, West Germany didn't had single party system.
B is not correct as there was no capitalism in East Germany and there was no state control in West Germany. It was the other way around.
D is not correct as there was no colonialism after WW2, while there was no totalitarianism, but democracy in West Germany.
To ensure a separation of powers, the U.S. Federal Government is made up of three branches: legislative, executive and judicial. To ensure the government is effective and citizens’ rights are protected, each branch has its own powers and responsibilities
