Final answer:
All group members share responsibility for ensuring their submitted work is free of plagiarism, but the person who plagiarised is most at fault. It's essential to talk to the instructor and be candid about the situation. Proper time management and adherence to academic integrity are crucial lessons to learn from such incidents.
Step-by-step explanation:
When faced with a situation where work was completed at the last minute and subsequently found to be plagiarised, it's important to consider academic integrity. All group members share some responsibility for the collective work, but it also depends on the expectations set by the instructor and the college's policies. If someone knowingly plagiarises and submits it as part of the group's work, that individual holds a significant portion of the fault. However, every member of the group is responsible for making sure the work is original and properly cited. In this case, approaching your instructor and discussing the situation is a critical first step, being honest about the group's oversight. Additionally, everyone in the group can learn from this incident about the importance of time management and collaboration to avoid last-minute work that can lead to issues like plagiarism.
