Question: What type of party system is there in the country the person who described the process of evaporation was from?

<P0-S0> The politics of the People's Republic of China takes place in a framework of a semi-presidential socialist republic run by a single party, the Communist Party of China. <P0-S1> State power within the People's Republic of China (PRC) is exercised through the Communist Party, the Central People's Government and their provincial and local representation. <P0-S2> The Communist Party of China uses Internal Reference to manage and monitor internal disagreements among the people of People's Republic of China. <P0-S3> Document Number Nine was circulated among the Chinese Communist Party in 2013 by Xi -- Li Administration to tighten control of the ideological sphere in China to ensure the supreme leadership of the Communist State will not be challenged by Western influences. <SEP> <P1-S0> Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. <P1-S1> They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. <P1-S2> They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. <P1-S3> Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds. <SEP> <P2-S0> while there is some international commonality in the way political parties are recognized, and in how they operate, there are often many differences, and some are significant. <P2-S1> many political parties have an ideological core, but some do not, and many represent very different ideologies than they did when first founded. <P2-S2> in democracies, political parties are elected by the electorate to run a government. <P2-S3> many countries have numerous powerful political parties, such as germany and india and some nations have one-party systems, such as china. <P2-S4> the united states is a two-party system, with its two most powerful parties being the democratic party and the republican party. <SEP> <P3-S0> Wang Chong (; 27 – c. 100 AD), courtesy name Zhongren (仲任), was a Chinese meteorologist, astronomer, and philosopher active during the Han Dynasty. <P3-S1> He developed a rational, secular, naturalistic and mechanistic account of the world and of human beings and gave a materialistic explanation of the origin of the universe. <P3-S2> His main work was the "Lunheng" (論衡, "Critical Essays"). <P3-S3> This book contained many theories involving early sciences of astronomy and meteorology, and Wang Chong was even the first in Chinese history to mention the use of the square-pallet chain pump, which became common in irrigation and public works in China thereafter. <P3-S4> Wang also accurately described the process of the water cycle. <SEP> <P4-S0> the national policy forum (npf) of the british labour party is part of the policy-making system of the party, set up by leader tony blair as part of the partnership in power process. <P4-S1> a provisional national policy forum had been established by blair's predecessor, john smith, in may 1993.
