The solution uses a SQL SELECT DISTINCT query to solve the problem. The DISTINCT keyword ensures that only unique city names are returned, eliminating any duplicates. The WHERE clause filters the data so that only rows with even-numbered IDs (ID%2=0) are considered. Thus, the query effectively retrieves unique cities associated with even-numbered station IDs.
Select distinct city from station where ID%2=0;
