What are the two leadership tasks and how is inclusiveness critical to their accomplishing those tasks successfully?

The two fundamental tasks of the leader are deciding what is to be done and how to go about doing it. After the leader has determined what should be done, it is crucial for them to communicate their vision of the work to others. When the group understands and agrees with the vision, the work will go more smoothly. Likewise, including group members in the plans to the extent possible increases both their understanding of and their commitment to the tasks that the leader has outlined.
