Question

in what way did the political situation in vietnam resemble that of korea in the 1950s?
both vietnam and korea were allied with the united states but then shifted allegiance to the soviet union.
both vietnam and korea were unified, communist countries who then voted to become democracies.
both vietnam and korea were divided and suffered when the south invaded the north.
both vietnam and korea were divided into a communist north and a non - communist south.

Explanation:

In the 1950s, both Vietnam (after the 1954 Geneva Accords) and Korea (after the 1950-1953 Korean War) were split along ideological lines: a Communist-led northern half and a non-Communist, U.S.-aligned southern half. The other options are factually incorrect: neither shifted allegiance from the U.S. to the USSR, neither was a unified Communist state that became democratic, and in both cases, the North invaded the South, not the reverse.

Answer:

D. Both Vietnam and Korea were divided into a Communist North and a non-Communist South.
