Step 1 : Introduction to the question "Which are the two landlocked countries in South America?"
...Paraguay and Bolivia are the two landlocked countries in South America. There are five countries bordering Bolivia and three countries that surround Paraguay. The landlocked status means these countries face geographic challenges related to trade. The lack of a sea coast means there's no port for exporting and importing cargo. Both countries depend on trucks and freight trains to move products instead of boats. Source: Reference.com
