Answer:The understanding of conservation
Explanation:
The law of conservation states that the amount of something is preserved even when the shape is altered or even when that thing is deformed.
For example putting the same amount of water in a short big glass and transferring it into a long thin glass doesn't change the amount of water that was initially in the first big short glass and children may not understand this at a certain age until they grow up to understand the law of conservation.
When creating legislation, a bill has to pass through both Congress and the President and can be challenged by the Judicial branch. Additionally, both Congress and the President must approve before the country goes to war.
