Over the centuries, the most effective means of "civilizing" natives to spanish culture was
(a) the encomienda system.
(b) the mission system.
(c) the distribution of mineral wealth.
(d) military occupation.

Option (B) is correct.

In past, the well-versed system of "civilizing" inhabitant to Spanish culture was "the mission system". The Spanish missionary attempts to incorporate the inhabitants to the culture were more fruitful than the terms utilized by several Spanish rulers.

Spanish missionaries in the Americas were known as the Catholic missions which were entrenched by the Spanish Empire in region starting from Mexico to ending as far as Chile.

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.
