macrosystem

Explanation:

The question above is related to "Bronfenbrenner's Ecological Systems Theory," which talks about the different structures of environment that could affect the development of a child. The systems are the following: Macrosystem, Microsystem, Exosystem and Chronosystem.

The "Macrosystem" is considered the outermost layer. It includes the customs, laws and cultural values. For example, if a society believes that education is very important for children, then they'd most likely prioritize building schools and providing educational assistance. This has a cascading effect towards the other systems, especially the microsystem.
