Newbold Plow - cast iron plow by Charles Newbold
The Newbold Plow
The plow evolved from the all-wood designs of antiquity, to the use of iron parts. In 1720, the first English patent for a wooden moldboard sheathed with iron was issued to Joseph Foljambe. From that the evolution to plows made with cast iron moldboards and shares occurred in Scotland in 1785 by James Small. These cast iron plows were then imported to the U.S.
Charles Newbold, born in Chesterfield, NJ (1780), spent his teenage years investigating the use of cast iron to improve on the heavy iron-clad wooden plow then available. He was issued the first US patent for a plow on 26 Jun 1797. The plow was cast as one piece—the moldboard, share, and land-side all cast together—with wooden handles and beam added.

The policy contributed most to the nuclear arms race was Mutual Assured Destruction
This means that both sides knew that any attack upon the other would be devastating to themselves, therefore restraining them from attacking the other. Each side possesses enough nuclear weapons to obliterate the other side that causes them to restrain from attacking afraid of the annihilation.

The statement is TRUE.
Old imperialism was characterized by direct occupation and dominance of a territory, and started with the arrival of the Spanish to America leaded by Columbus in 1492. Colonized territories depended on their mother country for political, economic, social and cultural issues. Apart from Spain, also other countries such as France, UK or Belgium created their own empires.
The relationships established with the colonist were mostly profitable for the mother country, specially in economic terms. Such system allowed the mother country to consume raw materials, minerals and other resources from the colonies only paying for the costs of their obtention or extraction, and to use them to produce manufactures. Subsequently, they traded the final products in the international markets, becoming powerful exporting nations. They even sold those final products back in the colonies.
