What is the overall effect of the syrian civil war

there was a couple but some of the more important  ones might be that an estimated 22million people had to leave there homes and because of the war there is now one of the biggest humanitarian crisis next to Yemen

one of the main reasons of the civil war was trying to get someone else into power

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.

a is the answer i believe.
