Final answer:
Gloria's strategy in borrowing notes from Richard is an appeal to commitment, aligning with the social exchange practice of balanced reciprocity, which is common among friends and acquaintances.
Step-by-step explanation:
Gloria is appealing to commitment when she asks to borrow Richard's notes.
She proposes a plan to copy the notes when Richard is not using them and reassures him that she will return them later the same day.
This strategy facilitates the process by minimizing the inconvenience to Richard and making the transaction feel secure, showing a clear understanding of the nature of the favor and the expectations involved.
Such an exchange reflects balanced reciprocity where a favor is done with the anticipation that it will be returned in the future, as generally found in exchanges among friends and acquaintances.
