The picture above depicts the berlin wall, which divided berlin in half from the 1960s to 1989. which type of boundary was the berlin wall?
a. an iron curtain
b. a physical barrier
c. a trade agreement
d. an artistic piece

The second alternative is correct (B).

The Berlin Wall was a physical barrier separating Germany from two nations: West Germany and East Germany.

After the end of World War II, a dispute arose between two economic systems, capitalism and socialism, represented respectively by the United States and the USSR, which disputed world hegemony. This period became known as the Cold War.

The Berlin Wall divided Germany between one country as Soviet influence, East Germany, and the other about American capitalist influence, West Germany.

The fall of the Berlin Wall in 1989 represented the end of the Cold War and the assumption of capitalism as a hegemonic regime.

hello!

according to the passage the most suitable options are two. the first one is "by leading the aef to victory in several key battles" like the battle of saint- mihiel and the battle of cantigny mentioned in the passage you copied here. the second one is "by the aef and allied forces defeat germany" since the passage says that his army destroy the german resistance in the meuse- argonne offensive. and also, "by insisting that the aef operate as an independent force".

hope this

i believe it is the second one.   if correct plz mark brainliest.
