Question:

Early American industry was given a boost by:

A) war

B) transportation and communication improvements

C) new power sources

D) mass production methods

E) monopolies

The right choice is D) mass production methods.

Explanation:

The early technological and industrial development in the United States was ignited by a unique combination of geographical, social, and economic factors.

The lack of workers in the United States made wages rates higher on a very frequent basis than the rates in the British and European markets.

This provided an incentive to mechanize some tasks which in turn became a great advantage to the advancement of its industry.
