Hi there!
Because this question has been posted before, I'll post my previous response here.
The case of Gibbons v. Ogden was a landmark Supreme Court case decided in 1824 concerning the power of the states to regulate interstate commerce. This case involved a steamboat owner, Thomas Gibbons, who did business between New York and New Jersey and the then governor of New Jersey, Aaron Ogden. Gibbons argued that the monopoly Ogden had was a violation of the commerce clause of the Constitution and therefore not valid. This proved to be the case. In a unanimous decision, the Supreme Court decided that this law conflicted with federal law and the powers the federal government had to regulate interstate commerce. Under the Constitution, Congress has all powers necessary and proper to carry into effect the laws that it passes. This reinforced that clause.
Answer:
A loose confederation of sovereign states and a weak central government were formed by the Articles, leaving most of the power with the state governments. The need for a stronger federal government quickly became evident and finally led to the 1787 Constitutional Convention.
Explanation:
It would be the development in agricultural knowledge/technology
Development in agriculture enable hunter/gatherer society to shift their behavior. Before this, they had to keep moving from one place to another in order to seek food to live.
After the development in agricultural knowledge/technology, the society now can stay in one exact place for a long period of time and relied on agricultural product as their main source food.
After living in one same place for a long time, the needs to build things to accommodate their living start to arise. They start to built several things and repeat the process every year. In the end, large cities were developed from the initially small hunter/gatherer society.
The two discoveries that brought a revolution in early man's life are:
1) Agriculture - It helped the early man to produce its own food. this innovation made possible new flux of innovations and ideas the husbandry and domestication of all modern cattle and pets (except dogs), the formation of soldiers and wars, the money, the origin of religion, writing and all the very basis of modern life. Developing all these new outcomes would be impossible without the cooperation and organized structure of agricultural societies.
2) Language and paintings - Language helps them to communicate with each other and painting which they did at that time helped Historians today to know about their life, language, etc.
Answer: The wall was the northernmost point of the Roman empire for 20 years between the 140s and 160s AD before its forces were withdrawn from Scotland by the mid 160s. Hadrian's Wall became once again the frontier of the province until the final withdrawal of the legions from Britannia in the early 5th century AD.
