Answer:
a) Identify ONE way in which the development of new technologies in the twentieth century changed the global economy.
The assembly line, invented by Henry Ford in the early twentieth century, changed the global economy throughout that century, because it allowed firms to standardize the production of a wide range of goods, from automobiles, to canned food, to clothing, making production more efficient and cheaper for the consumer in the process.
b) Explain ONE similarity in how the development of new medical innovations and agricultural technologies in the twentieth century affected the environment.
Both medical innovations like vaccines and agricultural technologies like the green revolution helped boost population growth, because more people could be fed, and less people died in childhood. This population growth created more pressure on the environment, and led to the climate change challenges that we face today.
c) Explain ONE major change in global culture in the late twentieth century.
In the late twentieth century, television first, and then the internet, became global means of communication that helped spread local cultures around the world. This changed local cultures, and made them more global, because now the world was more interconnected, and intercultural change became easier.
