What was established in 1854 in an attempt to assist with the voting process in kansas?

None of the above. I think it is the Kansas-Nebraska Act.

The correct answer is A.

The speech delivered by Winston Churchill, when he used for the first time the expression "iron curtain" clearly established a border and an attitude of confrontation between the two blocs that have aroused in the European continent after WWII. On the Eastern side, the Soviet Union together with the states under its communist sphere and, on the other sid,e the Western powers that had won the war (France and UK) that were allies of the United States together with all the Western countries under their capitalist influence.

These were the two blocs that would be subsequently confronted during the Cold War.
