Pauline and leo call their grandchildren every week and drive the 300 miles to visit several times a year. they even text message their grandchildren on their cell phones occasionally, just for fun. social scientists would say that pauline and leo have what type of relationship with their grandchildren

The correct answer is a companionate relationship.

A companionate relationship between grandparents and their grandchildren is characterized by grandparents who are regularly in contact with or interactive with their grandchildren. Companionate grandparents are more friendly, supportive and relaxed in their bond with their grandchildren. Rather than focusing on disciplining their grandchildren, companionate grandparents serve as companions or "pals" to their grandchildren.
