How does intuition fit into the larger discussion of cognition?

Intuition is an immediate understanding, knowledge, derived neither from perception nor from reasoning. It’s an automatic, effortless feeling that often quickly motivates you to act. It helps in making a mental grouping of similar objects, events, ideas or people .

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
