The accurate summary of the United States' involvement in World War I is:

The U.S. was initially politically neutral and involved only economically. However, once they entered the war in 1917, their military involvement helped force an armistice and eventually led to Germany's surrender.

To arrive at this answer, we need to analyze each option and determine its accuracy based on historical facts.

Option 1 states that the U.S. was involved economically, providing critical resources for both Allied and Central powers, which led to a German armistice. This is not entirely accurate because while the U.S. did provide economic support to the Allied forces, it did not directly contribute to a German armistice.

Option 2 suggests that the U.S. joined the Allied forces in 1914 but only sent troops in 1917, leading to Germany's surrender. This is incorrect because the U.S. did not officially become part of the war until 1917.

Option 3 accurately describes the U.S. initially being politically neutral and involved solely economically. However, it later entered the war and played a key military role, which contributed to the armistice and Germany's eventual surrender.

Option 4 is completely inaccurate, as the U.S. never joined the Central powers during World War I.

The first option accurately summarizes the involvement of the United States in World War I. The U.S. initially remained politically neutral but was involved economically, providing critical resources for both the Allied forces and the Central powers. However, once the U.S. entered the war in 1917, its military involvement helped force an armistice, ultimately leading to Germany's surrender.
