Answer:
When we look at a map of the modern Korean peninsula, we can see that North Korea and South Korea are divided by the 38th parallel.
Step-by-step explanation:
North Korea, which is a communist country, is to the north of the parallel, and South Korea, a market economy, is to the south of the parallel.
The Korean peninsula was divided after the Korean War ended in 1953. There are two main reasons why the north of the peninsula became a communist country: it had more industry at the time, and was closer to the Soviet Union and Communist China.
The South became a capitalist economy thanks to the support of the United States. It was the poorest of the two at first, but in the last decades, South Korea has seen a lot more economic development than North Korea.
Nowadays, South Korea is an developed country like Japan, while North Korea is a very poor nation.
