Question

read the quotation by president woodrow wilson.
we enter this war only where we are clearly forced into it because there are no other means of defending our rights.
according to this quotation, wilson argues that the united states entered world war i because it
wanted to pursue a peaceful resolution to the war.
feared further aggression by the central powers.
sought to protect the central powers from defeat.
worried that the economy would collapse.

Explanation:

Wilson's statement "We enter this war only where we are clearly forced into it because there are no other means of defending our rights" implies a defensive stance. Fear of further aggression (by the Central Powers) would be a reason to defend rights as aggression could threaten those rights. Pursuing a peaceful resolution (first option) contradicts entering the war. Protecting Central Powers (third option) is opposite of US role in WWI (they fought against Central Powers). Worrying about economy (fourth option) isn't mentioned in the quote about defending rights.

Answer:

feared further aggression by the Central Powers.
