Traditional family structures in many cultures often involved extended families living together, with multiple generations under one roof. Grandparents, aunts, uncles, and cousins played active roles in daily life, childcare, and decision-making. In contrast, 21st-century Western societies often emphasize nuclear families (parents and children) living independently. While this offers greater personal autonomy, it can sometimes lead to less direct family support and a greater reliance on external institutions for services like childcare or elder care. However, modern technology also allows nuclear families to maintain strong connections with extended family members who live far away. Which statement best summarizes a key difference and a mitigating factor regarding family structures between the past and the 21st century, as presented in the text?
A) Past families were smaller and more independent, while modern families are larger and more communal.
