Explanation:

- Lynch's research focused on understanding the class dynamics within an economically disadvantaged, rural farming society.

- Lynch's study provides insights into how these factors interact and affect the social structure.

Option 3: Vietnam

- Vietnam, with its agrarian roots, is a potential candidate for such research, but not in this instance.

Option 4: Malaysia
