Answer:
Mesosystem
Explanation:
Dr Adams is observing how interactions between parents and teachers develop, therefore this sphere is named "MEsosystem" for it is immediately after the microsystem where children have direct interactions at home.
This means that relationships in this sphere will have a positive or negative impact on development: they involve the links for home and school, between peers and family, and between family and community-
The mesosystem forms a basic chain in Bronfenbrenner’s theory of development, where further systems are at stake.
