Explanation:

The gauchos are the Brazilian people born in the state of Rio Grande do Sul, in the south of Brazil. Rio Grande do Sul is a Brazilian state that borders Paraguay, Argentina and Uruguay.

The fields of Rio Grande do Sul are called pampas gauchos. The biome formed by these fields, which also extend through Uruguay and Argentina, is denominated Pampa, indigenous term Quechua that means flat region. The Pampas are a region of rich biodiversity, with very fertile soil, where agricultural activities predominate in which the gauchos work.

the arab empire adopted the muslim religion as their main belief. arabs would influence the people from the territories they invaded towards islam (the muslim belief).

nevertheless, throughout the history of the arab empire, rulers brought intellectual individuals from other religions to their centers of learning. these other foreigners included jews, christians, greeks, persians, and indians.   these resulted in the adoption of important knowledge developed by these cultures by the arabic empire. for example, the works of aristotle were translated from greek to arab and indian scientists brought the numerical concept of "zero" to the arabs.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
