Final answer:
The technique called Mining involves a team member identifying and bringing to light buried disagreements within the team.
Step-by-step explanation:
The technique that requires one team member to assume the role of extracting buried disagreements within the team and shedding light on them is known as Mining. Mining is a process used in team discussions and conflict resolution where a team member, often a facilitator, actively searches for buried or unspoken issues, brings them to the surface, and helps the team address them constructively. It's important for the success of the process that the team member doing the mining stays neutral and helps the team to understand different perspectives without taking sides.
