Hi there hope this helps you and is enough!
I believe the answer is: Maintenance role
In an organization, people who held the maintenance role would played a crucial role in maintaining a certain level of performance/productivity among other members. This could be done by doing things such as, providing emotional support, relieving working tension, giving counseling for troubled members, etc.
The correct answer is present progressive. The present progressive is used for an event that continues to occur at the present moment in time. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
