America changed drastically because shortly after the revolutionary war they established their first system of government and began electing their own leaders “ in this case the president” and over the years expanded West with the Louisiana purchase in 1803 and other territories west of the Mississippi. In 1865 civil war broke out between the north “ the union” and the south “ the confederacy” over the terms of slavery and president Lincoln created the 13th, 14th, and 15th amendment giving slaves the same right as any American.

Answer:
The last five decades comprise the period from 1970 to 2020. Three achievements are of great importance:
- Massification of personal computers: helped by Bill Gates' Microsoft and Steve Jobs' Apple, personal computers became common in offices in the late 1980s, and common in households in the early and mid 1990s, increasing productivity, and literally chaging the world.
- Internet: the internet was not invented in the last five decades but it became a mass service in the late 1990s. Without the internet, computers (and nowadays smartphones) would not be as powerful and important. The internet has changed every single aspect of our lives, from the way we communicate to the way we work.
- The end of the Cold War: this is a political and economic achievement, not a technological one like the previous two. However, it is still of great importance. Starting with the fall of the Berlin Wall in 1989, and ending with the collapse of the Soviet Union in 1991, the end of the Cold War marked the origin of the world order in which we live today, a world order where capitalism and representative democracy are considered the best alternatives for economic and social organization.
