The knowledge gap

Explanation:

The knowledge gap is based on a Hypothesis that suggests that absorption of knowledge differs with differences in socio-economic status of individuals those with high socioeconomic status seems to absorb

information faster than those at the lower status

This doesn't mean that those who have lower socioeconomic status know nothing but it just states that acquiring information and absorbing it is much faster and better for those with high socioeconomic status.

According to this hypothesis there is a belief that the higher the socioeconomic status of an individual the better are the chances to receive teh best education , with better education a person is able to acquire , comprehend and effectively use that information because they have been previously equipped on how to search for information and how to use it.

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.
