Why is it important to study organizational culture?

It allows us to understand how organizations adapt and integrate the shared assumptions and values of the people working in the organization.

It allows us to anticipate potential dysfunctions that impede adaptive functioning.

It allows us to understand and address obstacles that hinder diversity management.

It is not important.

It allows us to create an organizational identity and leverage diversity to create core competences.

All the answers, EXCEPT, the obviously erroneous one that infers that you would be required to study theory that had NO value to your capability as an organizational manager.
