Explanation:
The correct answer is B) encouraging the United States to avoid political entanglements in Europe.
Unfortunately, you forgot to include the excerpt, Without it, we had to do some deep research to find information about it.
We found that the excerpt is referring to the famous "Quarantine Speech" delivered by United States President, Franklin D. Roosevelt.
The ideas expressed in the excerpt differed from the prevailing United States approach to foreign policy issues primarily in that Roosevelt was encouraging the United States to avoid political entanglements in Europe.
We are talking about the conflictive and turmoil years previous the beginning of World War II. The situation in Europe was complicated and tensions grew as Adolph Hitler and the Nazi party increased the tome of its foreign policy and aspirations.
On October 5, 1937, United States President Franklin D. Roosevelt delivered the Quarantine Speech in the city of Chicago, Illinois. He had decided to maintain the foreign policy of neutrality before the tensions in Europe.
In the speech, he talked about some lawless nations that did not want to maintain peace in the region. He never mentioned any names but it was obvious he was talking about Germany, Italy, and Japan.
Correct answer: Russia's withdrawal from the war (World War I).
Russia withdrew from The Great War (which we now call World War I) after the Bolshevik Revolution brought Vladimir Lenin and the communists to power. Revolutionary activity broke out in Russia in February, 1917 -- during the time of World War I. Germany and Russia were on opposite sides in that war, and the German authorities helped Lenin, in exile, return to Russia in order to foment further revolution there and hurt the Russian government's ability to wage war in Europe. The major revolution in Russia, known as the Bolshevik Revolution, occurred in the fall of 1917. In March 1918, the new Soviet Russia government under Lenin ended its participation in the war, signing the Treaty of Brest-Litovsk.
I don't know fully so I'll narrow it down to two answers.
