What could be the end goal of decoding the notes?

The end goal of decoding the notes is to access obscured information. This process typically involves translating or interpreting a message that has been written in a way that is not immediately understandable, such as through code or shorthand. By decoding the notes, one aims to uncover hidden meanings or retrieve important details that may be essential for understanding the content fully. This is often important in various contexts, such as security, intelligence, or even personal communication, where clarity and comprehension are critical for further actions.

The other options, while related to communication, do not capture the primary intent behind decoding. Creating a new message implies generating information rather than revealing existing content. Rewriting the notes clearly suggests an editing process rather than the act of uncovering information that has been deliberately obscured. Sharing them with a larger audience aligns more with dissemination rather than the initial step of decoding aimed at understanding the original message itself.
