(mc)which factor explains the rise of isolationist sentiment in the united states during the decade after world war i? president wilson’s pledge to return to a policy of neutrality the desire to avoid entanglement in foreign conflicts the spread of a european economic crisis to the united states the failure of congress to give financial support to war veterans

The correct answer is "the desire to avoid entanglement in foreign conflicts."

After World War I, President Woodrow Wilson wanted to create a League of Nations (which shows that statement 1 is incorrect). This League of Nations was supposed to be an international organization that countries joined in order to maintain world peace.

 However, Congress did not pass the law necessary to become part of this league. This was the United State's way of telling Wilson that we no longer wanted to get ourselves involved in the affairs of other countries.
