Maintenance was often done by slaves. The Romans were among the first civilizations to harness the power of water.

Wallace defended segregation and this were his main arguments:
<span>-The Constitution did not require white and African American children to attend the same schools.
-Social separation of blacks and whites was a regional custom; the states should be left free to regulate their own social affairs.
-Segregation was not harmful to black people.
-Whites were making a good faith effort to equalize the two educational systems. But because black children were still living with the effects of slavery, it would take some time before they were able to compete with white children in the same classroom.
Hope this helps!! :)

The amount of territory the US currently has would have been completely different if the national government could only legislate based on what is written in the constitution.
A perfect example of this is the power to purchase land/territories from other countries. This was first done by Thomas Jefferson with the Louisiana Purchase of 1803. The US Constitution does not say that the president has the power to buy land from other countries. However, Jefferson said that this power was "implied" by the Constitution.
This idea of an implied power greatly changed the presidency/national government. Several presidents after Jefferson would follow his lead by making deals with countries for territory.
If it wasn't for this concept of implied powers, the US may not have grown to the 50 states we know it as today.
Where there any choices? This is true for a lot of countries: Basically all European countries with the exception of those that never fell to the Nazis :UK, Switzerland, Sweden, Spain, Portugal.
