Final answer:
Teresa suggests using a coding system to explain how the Maze might be a "code". This system allows for the identification and interpretation of patterns within the Maze, similar to deciphering a code.
Step-by-step explanation:
Teresa suggests that the Maze might be a "code" by considering a coding system for cross-referencing different features of the text. She mentions that some students use colors or numbers to indicate different elements of the text, such as nature imagery or plot and character. This coding system allows for the identification and interpretation of patterns and relationships within the Maze, similar to how a code is deciphered and understood.
