Explain the factors that motivate the hybrid scheduling approach of the ‘scheduler activations’ design (instead of pure user-level or kernel-level scheduling).

Efficient, custom scheduling takes place inside processes, but the allocation of a multiprocessor’s processors to processes can be globally controlled.
