Answer: Religion.
If you google the reason for the conflicts in Southwest Asia you find a variety of answers. I found this to be the most clearly written:
The conflicts are caused by people who are fighting for religion, land and natural resources. What I mean by people fighting over land is some say that god gave them that land and people are still trying to claim it. With there natural resources such as oil, gas and etc. they want it in order to make money. And to become a better military force. With religion, they fight by saying that there religion is right and the other religion is wrong. We could help by learning about each other religions and explaining it to others. With the land we could as the US let them handle it and not let them caught up in their conflict. In regard of other countries military's we need to be watchful of what they are doing and not step them unless its nessarcry. It is important to learn about their culture. Because to be better prepare in case of war and knowing who you are fighting against.
The correct answer is D. Pooling of unusually warm water in the eastern tropical Pacific.
Explanation
The Niño phenomenon is a climatic event that is related to the warming of the equatorial eastern Pacific Ocean. This phenomenon usually has great effects in the continental zone of equatorial America, because it produces abundant rains and in some areas it causes the fish to move. The irruption of these warm waters is due to the atmospheric difference between the eastern or western Pacific Ocean. So, the correct answer is D. Pooling of unusually warm water in the eastern tropical Pacific.
