\the partition of korea into two zones dominates the political and economic life of the peninsular. the division of korea at the 38th parallel has turned into a hard and fast boundary which cuts off all intercourse between the northern and southern halves of the country, except for the exchange of mail and the transfer of surplus electric power from north to south korea.\
–the situation in korea, 1947 report
the passage says that the partition of korea
○ divided the land but left the korean economy running well.
○ encouraged communications between the two parts of the country.
○ divided the country, both in its political and economic life.
○ discouraged communism from spreading into korea from china.

Explanation:

The passage states "The partition of Korea into two zones dominates the political and economic life of the peninsular" and notes the boundary cuts off most intercourse between the two halves. This matches the third option, while the other options contradict the text: the first claims the economy runs well (not stated), the second says communications are encouraged (the passage says most are cut off), and the fourth mentions discouraging Communism (not referenced in the passage).

Answer:

divided the country, both in its political and economic life.
