Question

the second industrial revolution in the united states resulted in the rapid growth of
o government.
o unions.
o taxes.
o cities.

Explanation:

The Second Industrial Revolution (late 19th - early 20th century) in the US brought about technological advancements (e.g., electricity, steel production). This led to the growth of industries. People migrated from rural areas to urban centers (cities) in search of jobs in these new - age industries. Unions had existed before the Second Industrial Revolution (e.g., early labor movements), and while they became more prominent during this period, the growth of cities was a more direct and rapid outcome. The growth of government and taxes was not as directly and rapidly tied to the Second Industrial Revolution as the growth of cities.

Answer:

cities.
