Homework 6 Possible answer 1 Problems: Many young people want to leave the countryside because they want to find jobs in the city. Opinions and reasons: This is a big problem for the countryside and city. More and more young people crowd into cities, so there are few people working in the countryside. But meanwhile, there are so many people in the cities that somebody may not find a job.
