Explanation:
Hello. You did not say what text you are referring to, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
A clue that a character has changed his mind occurs when he begins to abandon positions he had previously established. In addition, this character can begin to support something that he did not support, or to adopt behaviors that he criticized, but that saw that they are not wrong or harmful.
Primary sources, for example, are witnesses. If there was a witness to a murder, they would be considered a primary source because they can give the police a first hand view of what happened. Published research, newspaper articles, and other media would be secondary sources as they are not at the event but just commentating and/or making observation from what they can tell from videos and gossip. Let me know if you have any more questions.
