___ assimilation occurs when a minority group enters the secondary sector of the larger society and participates in the same public institutions as the dominant group (such as churches, clubs, schools and workplaces).

This is known as structural assimilation.

Explanation:

Structural assimilation occurs when a minority group incorporates into a larger, dominant group's structure.

As the example states, the minority group enters the secondary sector of the large society and therefore participates in the same public institutions as this dominant group because the minority has been incorporated into it.

This includes churches, clubs, schools and workplaces.
