Question: What is the major advantage of the adaptive immune system?

Answer:

The distinct advantage of the adaptive immune system is its ability to select B cells and T cells that have high-affinity receptors for new antigens and to stimulate them to replicate and provide a specific, fine-tuned response to foreign invaders.
