Read the given passage and answer the following questions carefully -
Child rearing has evolved significantly over the past few decades, shaped by changes in societal norms, technological advancements, and shifting parental roles. In the past, child rearing often adhered to rigid, authoritative models where children were expected to follow strict rules set by their parents. This approach emphasized obedience and discipline, with limited room for dialogue or emotional expression. Today, modern child rearing practices have become more flexible and child-centric. Emphasis is placed on nurturing a child's individuality and emotional well-being. Parents are now more likely to adopt authoritative parenting styles that balance guidance and structure with warmth and responsiveness. This shift has been influenced by research highlighting the long-term benefits of positive reinforcement, open communication, and emotional intelligence. Technological advancements have also significantly impacted child rearing. While parents in previous generations had to rely on books and advice from family or friends, today's parents have access to a wealth of information through the internet, allowing them to make informed decisions about parenting strategies. However, this also means that modern parents face challenges such as managing screen time and ensuring their children’s online safety. Moreover, the roles of mothers and fathers have become more fluid, with both parents often sharing responsibilities equally. This shift has been driven by increased awareness of gender equality and the rise of dual-income households. In essence, child rearing today is more nuanced, reflecting a deeper understanding of child psychology and a greater emphasis on fostering a supportive and communicative family environment.
