Final answer:
Lloyds' new family structure, which includes multiple generations living together, would be termed an extended family.
Step-by-step explanation:
When Lloyds invites his mother to live with him, his wife, and two sons, the new family structure would be termed an extended family. An extended family includes two or more family units functioning as a single integrated family and may involve two or more generations. This is different from a nuclear family, which typically consists of parents and their immediate offspring. Extended families can provide economic and social support, and this arrangement is becoming more common in the United States due to factors such as economic need or housing challenges.
