Considering how early intervention programs to improve intellectual development have some mark improvement in the iq of participants it can be inferred that the main reason children from low ses families earn lower scores on iq test is that

the parents have difficulty providing an intellectually stimulating environment for their children.

Explanation:

SES stands for socioeconomic status.

Parents form high Socioeconomic status are more likely to have money to spend for the development of their children, while parents from low Socioeconomic status barely have enough money to survive.

Because of this, children form high economic status are more likely to grow up with various toys and entertainment that can stimulate brain (such as different variety of legos, access to expensive art tools/coloring books, musical instruments to play with, etc). When they grow up the average IQ of children from high SES tend to be higher compared to children from low SES

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.

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
