Answer:
the leader
Explanation:
A group will usually be only as good as the leader of the group.
The leader of a group is the person that coordinates and controls the activities of the group. The skills of the leader and the experience he/she has will determine how well-coordinated, or otherwise, the group would be.
Hence, the quality of a leader of a group always rubs off on the general outlook of the group. That is why it is said that a group will usually be only as good as the leader of that group.
