Step 1: Introduction
The United Nations Congress on Crime Prevention and Criminal Justice is a global forum held every five years. The task is to arrange four congresses in chronological order.
Step 2: Congress Dates
Here are the years each congress was held:
C. London: Second UN Congress, held in 1960.
B. Stockholm: Third UN Congress, held in 1965.
A. Kyoto: Fourth UN Congress, held in 1970. (Note: The Fourteenth Congress was also held in Kyoto in 2021, but only the 1970 congress fits chronologically.)
D. Milan: Seventh UN Congress, held in 1985.
Step 3: Solution
The chronological order, from earliest to latest:
1. London (1960) $\rightarrow$ C
2. Stockholm (1965) $\rightarrow$ B
3. Kyoto (1970) $\rightarrow$ A
4. Milan (1985) $\rightarrow$ D
The correct sequence is C, B, A, D.
