I think the American invention that has been the most important to the United States is the invention of the internet by John Blankenbaker in 1971 and developed by the US Army. This is the most important invention because it has allowed extraordinary advances in communications and up today, every single office and home has one computer or PC with Internet. Through the internet, we can study, work, connect with other people, and do so many important activities in government, trade, e-commerce, and more.

i would say your answer is a)

sorry if im wrong

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
