Answer:
The correct words, that fill the gaps are: visible artifacts; underlying values
Explanation:
The most visible level of a culture is that of its productions and creations, which is given by its physical and social environment. All explicit manifestations of culture can be considered artifacts of an organization. From formal conventions such as strategy, structure, or information transmission systems, to informal manifestations, rumors, legends, or stories that are passed down from generation to generation.
The underlying values, those assumptions, beliefs, attitudes, feelings and thought processes that constitute the real culture. If compared with the iceberg, its depth would be studied, that is, what is not distinguished by being at sea level. In reality it is the underlying values that make up the culture of an organization. Managers and administrators must observe, analyze and use visible behaviors to shape the real values of the organization and strengthen the organizational culture.
