Explanation:

You might be tempted to choose the first answer, about the Soviet detonation of its first atomic bomb.  However, the Western Allies formed the military alliance known as NATO in April 1949, and the Soviets did not detonate their first atomic bomb till August of 1949.

The communist coup in Czechoslovakia was a main cause of concern that led to the formation of the North Atlantic Treaty Organization (NATO).

The Office of the Historian of the United States lists these events of 1947-48 as strong influences that led to the formation of NATO:

The Office of the Historian reports:  "These events caused U.S. officials to grow increasingly wary of the possibility that the countries of Western Europe might deal with their security concerns by negotiating with the Soviets. To counter this possible turn of events, the Truman Administration considered the possibility of forming a European-American alliance that would commit the United States to bolstering the security of Western Europe."

interdependence is when all participating groups and individuals depend on each other. if you depend on one anothers goods, you end up trading in order to get the items you're looking for. (for ex: if i have food and you have water, we trade in order to depend on each other to live)
