(11.5) why did the year 1860 represent a turning point in u.s history?
o the united states became the worlds wealthiest country.
o the united states gained new territories and became an imperial power.
o the united states became the worlds largest country in the area.
o the united states ended all foreign trade and focused on internal issues only.

Explanation:

In 1898, events like the Spanish - American War led to the US acquiring territories (e.g., Puerto Rico, Guam, Philippines) and emerging as an imperial power, marking a shift from its previous non - imperial stance, thus making 1898 a turning point. The other options: the US was already wealthy, was not the “first largest” in the area, and didn't end all foreign trade/focus on internal issues.

Answer:

The United States gained new territories and became an imperial power.
