Placing the earliest first, arrange the following countries in the chronological order in which they granted universal adult franchise: 1. USA 2. Sri Lanka 3. Japan 4. India

The USA granted universal adult franchise (with the 19th Amendment giving women the right to vote) in 1920, though full voting rights for all races were secured by the Voting Rights Act of 1965. Sri Lanka (then Ceylon) granted universal adult franchise in 1931, making it one of the earliest in Asia. Japan extended universal adult franchise in 1945 after World War II. India granted universal adult franchise with the adoption of its Constitution in 1950. However, considering the standard chronological order accepted in textbooks: USA (1920), Sri Lanka (1931), Japan (1945), India (1950), the correct sequence is 1, 2, 3, 4.
