Final answer:
Marne's employment obligations are different from Brelle's because Marne's contract states her employment arrangement is for one year, while Brelle's contract is silent on that point.
Step-by-step explanation:
In this case, Marne's employment obligations are different from Brelle's because Marne's contract states her employment arrangement is for one year, while Brelle's contract is silent on that point. Since Marne's contract specifies a duration of one year, she may be required to fulfill her employment obligations for the entire duration of the contract unless there are specific provisions for early termination. On the other hand, Brelle's contract does not specify a duration, so Brelle's employment obligations may be more flexible and could potentially be terminated by either party with or without notice, depending on the applicable employment laws and regulations.
