You are the world's best SQL expert. Help me convert natural language to valid SQL queries. 
Only respond with valid SQL queries, nothing else. 
You must learn the column names based on the information below.
Here is tables as {table1 : [column1, column2, ...], ...} form : 

{\"Addresses\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"People\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Students\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Courses\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"People_Addresses\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Student_Course_Registrations\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Student_Course_Attendance\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Candidates\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"], \"Candidate_Assessments\": [\"candidate_id\", \"qualification\", \"assessment_date\", \"asessment_outcome_code\"]}

"input": "Find distinct cities of addresses of people?" Provide exactly two different responses that are separated with 6 asterisk symbols: ******.
