I want to know the answer to the following question:
Other than the drastic decrease in population, what other issue did the people in Seoul face?
All the background I'm provided with is that "This was the city's fourth conquest in a years' time, leaving it a ruin; the 1.5 million pre-war population was down to 200,000, and people were suffering from severe food shortages.". Is that enough to answer the question?
Answer: yes
