Read the text and answer the question. In many cultures of the past, extended families often lived together in the same household or very close by, sharing responsibilities and resources. Children were typically raised with the constant presence of grandparents, aunts, uncles, and cousins. Meals were large, communal affairs. In contrast, 21st-century lifestyles in many parts of the world often emphasize nuclear families (parents and children) living independently. While technology allows for easy communication, daily interactions with extended family members might be less frequent, and individual privacy is often highly valued. What is a clear difference in family living arrangements between the past and the 21st century, according to the text?
A) Past families had more privacy than modern families.
