¿cómo impactaron los avances tecnológicos el crecimiento poblacional y la
urbanización en estados unidos?

the technological advances improved communication and transportation, which
facilitated urbanization and a rise in population in large cities.

there was an increase of migration from urban areas to rural areas due to expanded
access to various types of transportation.

the technological advances had little impact until the invention of the airplane, which
led the way for domestic flights to occur between larger cities.

there was an increase of migration from rural areas to urban areas due to the expanded
access of higher education and business training.

Explanation:

Technological advances like railroads, telegraphs, and later automobiles improved communication and transportation networks. This made it easier for people and goods to move, drew workers to urban industrial centers, and supported population growth in large cities. The other options are incorrect: migration was rural to urban (not urban to rural), technological advances (like rail) impacted urbanization long before airplanes, and the primary driver was job access from industrial tech, not just education/training.

Answer:

The technological advances improved communication and transportation, which facilitated urbanization and a rise in population in large cities.
