Final answer:
The question lacks specific context about the character Perry and the text in question. Generally, characters altering statements to police do so out of self-preservation or guilt, revealing aspects of their personalities such as cunning or worry.
Step-by-step explanation:
The student's question likely pertains to a character named Perry from a literary text, but the text is not specified in the question. In general, when a character in literature seeks to make changes to their initial statement to police, it usually suggests a concern with how they are perceived or a fear of legal repercussions. The character may realize the potential consequences of their original statement and want to alter details to protect themselves. This might suggest that the character is either cunning, feeling guilty, or worried about the implications of the truth.
Without the specific context of the novel or text in consideration, we cannot accurately ascertain Perry's reasons or what these say about his character. However, if one were to analyze such a scenario, they would typically look into the motivations behind the character's desire to change their statement and how those motivations align with the character's overall personality and development throughout the story.
