the years 1050 to 1300 have been described as europe's a. low ages c. high ages b. middle ages d. high middle ages  

The correct answer is the The High Middle Ages.

This period started in 800 and lasted until 1300.  In this period we had the development of feudal society and the increasing of spheres of power in the hand of some individuals. We had a 3 different segregated castes: Kings(With control of large portions of land), Lords (Carried out the king's will) and Peasants (who worked the land and paid tributes). Populations soared as Europe enjoyed generation after generation of agriculture success during a period known as the Medieval Warm Period.

the answer wold be b) travel among nations should be regulated by an international organization

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
