What are two reasons that H. G. Wells decided to include information about the establishment of the United States through the river steamboat and the railway in this passage?
to show how the steamboat and railway increased production and trade
to show how the United States population has stayed uniform despite its growth
to show how the 18th century was based in liberal ideas and thinking
to show how the country was missing a census and could not account for the country's population
to show how new transportation inventions were the leading cause in the rapid population growth
