Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

          Happiness is a universal goal, yet its ingredients differ across societies and cultures. For some, safety and security are paramount, as demonstrated by Singapore. Known for its strict laws and highly regulated environment, Singapore provides a clean, orderly, and safe place for its citizens. The government ensures access to basic necessities such as housing and healthcare, significantly reducing poverty and promoting equality. While personal freedoms may be limited, many Singaporeans find satisfaction in the stability and quality of life their country offers, showing that happiness can stem from collective security.

        In contrast, Mexico highlights the importance of social connections in achieving happiness. Despite challenges like poverty and limited access to essential resources, Mexicans often prioritize relationships with family, friends, and neighbors. Simple acts like sharing meals or gathering in the community foster a sense of belonging and emotional well-being. Psychologists have long noted that feeling part of a larger social group can be a powerful source of happiness, even when material wealth is scarce. For them, the joy derived from relationships often outweighs material concerns.

       The role of money in happiness, however, is often debated. In Mexico, many individuals live in similar financial conditions, reducing the pressure of economic competition. When neighbors lack expensive possessions, individuals are less likely to feel dissatisfied with their own circumstances. This suggests that relative wealth and equality may have a stronger influence on happiness than absolute income.

       Ultimately, there is no universal recipe for happiness. Factors like security, freedom, social bonds, and financial equality all play a role, but their importance varies depending on individual and cultural values. Happiness, therefore, remains a deeply personal and multifaceted pursuit, shaped by our unique perspectives and circumstances.

Read the following passage about lifelong learning and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

[I] Lifelong learning is the ongoing, voluntary, and self-motivated pursuit of knowledge for personal or professional development (Knowles, 2020). [II] This concept emphasizes that learning does not stop after formal education, but rather continues throughout an individual's life, adapting to changing circumstances and needs. [III] In today’s fast-paced world, where technology and job markets evolve rapidly, lifelong learning has become increasingly essential. [IV]

One of the primary benefits of lifelong learning is its ability to enhance employability. Individuals who engage in continuous education are more likely to keep their skills relevant and competitive in the job market. According to a report by the World Economic Forum (2021), over 50% of employees will need reskilling due to technological advancements in the coming years. Lifelong learners are better equipped to adapt to these changes, making them more attractive candidates for employers.

Moreover, lifelong learning contributes to personal fulfillment and mental well-being. Engaging in new learning experiences can stimulate the brain, foster creativity, and improve cognitive function. Research indicates that individuals who pursue learning opportunities throughout their lives tend to report higher levels of happiness and life satisfaction (Smith & Johnson, 2019). Whether it is taking a course, learning a new language, or picking up a new hobby, the process of acquiring knowledge can be enriching and enjoyable.

In addition, lifelong learning promotes social engagement and community involvement. Participating in educational programs or community workshops can foster connections with others who share similar interests. This social aspect of learning can enhance one's sense of belonging and support networks, which are crucial for mental health (Jones, 2022).

Overall, lifelong learning is not just an individual responsibility; it requires support from educational institutions, employers, and communities to create an environment conducive to continuous education. By fostering a culture of learning, society can better prepare individuals for the challenges of the future and ensure that everyone has the opportunity to thrive.

(Adapted from The Importance of Lifelong Learning by Knowles, Smith, Johnson, and others)
