Answer: By working together voluntarily
Explanation:
Before the current time-zones in the United States and Canada came into effect, the various towns and cities had their own times depending on the position of the sun amongst other things. This made scheduling a nightmare for the Railroad comapnies who would have to list multiple times for the same train.
Burdened by this and powerful enough to change it, the Railroad companies met and decided to work together voluntarily to divide the United States and Canada into 4 zones which were quite similar to the ones in use today. These zones went into effect in 1883 and were officially adopted by Congress in 1918.
The primary outcome of the American Revolution was the independence of fourteen formerly British colonies in North America; thirteen of which would immediately form the United States and the fourteenth, Vermont, which would accede to the United States shortly thereafter.
Some other causes:
1. The Founding of the Colonies.
2. French and Indian War.
3. Taxes, Laws, and More Taxes.
4. Protests in Boston.
5. Intolerable Acts.
6. Boston Blockade.
7. Growing Unity Among the Colonies.
8. First Continental Congress.
