Question

read the excerpt.
the united states is the worlds best hope, but if you fetter (tie) her in the interests and quarrels of other nations, if you tangle her in the intrigues of europe, you will destroy her power for good and endanger her very existence. -senator henry cabot lodge, 1919
based on the excerpt, why did many united states senators reject the treaty of versailles?
they believed the treaty punished germany too harshly.
they feared the treaty would force the country into global conflicts.
they supported wilsons fourteen points over the treaty.
they predicted the treaty would lead to domestic conflicts.

Explanation:

Senator Lodge's statement implies that involving the US in European affairs (as the Treaty of Versailles would do) could be dangerous. The idea of "fettering" and "tangling" in other nations' interests and quarrels suggests a concern about being drawn into global conflicts. The other options are less supported: there's no indication of support for Wilson's Fourteen Points (opposite, as they rejected the treaty which was related to post - WWI peace including Wilson's ideas), no mention of predicting domestic conflicts, and the treaty's punishment of Germany is not the main focus of Lodge's concern (his focus is on US involvement in Europe).

Answer:

They feared the treaty would force the country into global conflicts.
