Hello. You have not shown which text this question is referring to, which makes it impossible for this question to be answered.
However, I can advise you to find the answer by helping you to recognize how an author of a text can give credence to Freudian theory.
Freudian theory basically refers to the power of the unconscious in our lives, shaping our personality, explaining who we are and even instigating the actions we do.
An article that wishes to give credibility, that is, to confirm that this theory is real, is exhibiting events, situations and actions that individuals provoked and that can only be explained through points of their unconscious. In other words, the author of the article must show evidence to prove Freudian theory. This evidence can be displayed through scientific experiments with scientific evidence and even articles by other authors being cited as research sources.
