Final answer:
The option 'spending money and education' is not considered a separate family function out of the choices provided, as education is included in the four main family functions, and spending money falls within the economic function of the family.
Step-by-step explanation:
The four main family functions identified by Sociologist George Murdock in his survey of 250 societies are sexual, reproductive, educational, and economic. These functions include regulating sexual relations, ensuring reproduction, teaching, and education within the family, and providing economic support.
Out of the options provided, 'spending money and education' is not considered a separate family function because education is already included as one of the four main family functions, and spending money is a part of the broader economic function of a family. In contrast, 'food and shelter', 'affection and love', and 'patterns and routines' are functions that can relate to the economic and educational roles, as well as the provision of emotional support within the family.
