Final answer:
After securing shelter and safety needs, according to Maslow's hierarchy of needs, the next level a single parent would seek to fulfill is love and belonging.
Step-by-step explanation:
According to Maslow's hierarchy of needs theory, once physiological and safety needs have been met, the next level of need a person would seek to fulfill is love and belonging. Since the social worker at the clinic has already arranged for a safe and secure apartment, which addresses the physiological need for shelter and the safety needs of the young, single parent and her children, the next level of need they would aspire to meet is love and belonging. This includes forming friendships, social connections, and family bonds. After love and belonging needs are met, individuals then strive for higher-level needs such as esteem and self-actualization.
