In what year did the U. S. shift from a rural agricultural nation to an urban-industrial nation? Which innovation had the greatest influence on the shift? Explain your reasoning.

1910. We can see that from the 50/50 split in 1900 to a 32/68 split in 1910, the statistical displacement says that 1910 was at least the year by which our nation had become an industrial nation. This shift was most directly influenced by by the trans-country communication such as telegraphs, Morse code, the telephone, transatlantic cables, etc. This allowed corporations to communicate faster and therefore grow at more rapid rate, allowing for the need of thousands of white collar jobs and industrial employment for young, single women and, unfortunately, children.

Explanation:

If you have an AMSCO US History book, pages 327-328 will help with this question.

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
