Question: Provide the competitors' names who joined the 2000 Summer.
Evidence: the competitors' names refer to full_name; the 2000 Summer refers to games_name = '2000 Summer';

SQL:
SELECT T3.full_name FROM games AS T1 INNER JOIN games_competitor AS T2 ON T1.id = T2.games_id INNER JOIN person AS T3 ON T2.person_id = T3.id WHERE T1.games_name = '2000 Summer'
