Question: What is the post ID and the comments commented in the post titled by "Group differences on a five point Likert item"?
Evidence: Title = 'Group differences on a five point Likert item';

SQL:
SELECT T2.Id, T1.Text FROM comments AS T1 INNER JOIN posts AS T2 ON T1.PostId = T2.Id WHERE T2.Title = 'Group differences on a five point Likert item'
