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.                                                                   

Which of the following is TRUE about happiness according to the passage?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer.

Global Issues: Gender Equality and Women’s Empowerment

Gender equality means that men and women have equal power and equal opportunities for financial independence, education, and personal development. Women's empowerment is a critical aspect of achieving gender equality. It includes increasing a woman's sense of self-worth, her decision-making power, her access to opportunities and resources, her power and control over her own life inside and outside the home, and her ability to effect change. Yet gender issues are not focused on women alone, but on the relationship between men and women in society. The actions and attitudes of men and boys play an essential role in achieving gender equality.

Education is a key area of focus. Although the world is making progress in achieving gender parity in education, girls still make up a higher percentage of out-of-school children than boys. Approximately one quarter of girls in the developing world do not attend school. Typically, families with limited means who cannot afford costs such as school fees, uniforms, and supplies for all of their children will prioritize education for their sons. Families may also rely on girls' labor for household chores, carrying water, and childcare, leaving limited time for schooling. But prioritizing girls' education provides perhaps the single highest return on investment in the developing world. An educated girl is more likely to postpone marriage, raise a smaller family, have healthier children, and send her own children to school. She has more opportunities to earn an income and to participate in political processes, and she is less likely to become infected with HIV.

Women's health and safety is another important area. HIV/AIDS is becoming an increasingly impactful issue for women. This can be related to women having fewer opportunities for health education, unequal power in sexual partnership, or as a result of gender-based violence. Maternal health is also an issue of specific concern. In many countries, women have limited access to prenatal and infant care, and are more likely to experience complications during pregnancy and childbirth. This is a critical concern in countries where girls marry and have children before they are ready; often well before the age of 18. Quality maternal health care can provide an important entry point for information and services that empower mothers as informed decision-makers concerning their own health and the health of their children.

A final area of focus in attaining gender equality is women's economic and political empowerment. Though women comprise more than 50% of the world's population, they only own 1% of the world's wealth. Throughout the world, women and girls perform long hours of unpaid domestic work. In some places, women still lack rights to own land or to inherit property, obtain access to credit, earn income, or to move up in their workplace, free from job discrimination. At all levels, including at home and in the public arena, women are widely underrepresented as decision-makers. In legislatures around the world, women are outnumbered 4 to 1, yet women's political participation is crucial for achieving gender equality and genuine democracy.

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

     [I] As the world grapples with the finite nature of fossil fuel reserves and the detrimental impact of climate change, the future of energy undeniably lies in renewable sources. [II] Scientists and engineers are making substantial advancements in the development of technologies that more efficiently harness solar, wind, hydro, and geothermal energy. [III] Although the transition to these renewable sources presents significant challenges, it is also regarded as a pivotal step towards establishing a sustainable and resilient energy system. [IV]

     One of the most promising advancements in renewable energy is the enhancement of solar panel efficiency. Progress in photovoltaic technology has led to the creation of panels that convert a higher proportion of sunlight into electricity. Likewise, wind turbines are becoming more and more efficient. They are capable of generating power even under low-wind conditions. These innovations are essential for making renewable energy more feasible and accessible to a broader population.

     However, the transition to renewable energy is fraught with obstacles. The intermittent nature of sources like solar and wind necessitates reliable storage solutions to ensure a consistent power supply. Although battery technology has seen significant improvements, further advancements are imperative to meet growing demand. Moreover, new infrastructure for distributing renewable energy requires expansion and upgrading to accommodate these new power sources.

     The economic impact of transitioning to renewable energy is another critical consideration. While the initial investment in renewable energy infrastructure can be substantial, the long-term benefits include reduced energy costs and job creation in the green energy sector. Governments and private enterprises are increasingly acknowledging the necessity of investing in renewable energy projects, which is crucial for fostering innovation and diminishing reliance on fossil fuels.

     Ultimately, the future of energy hinges on our capacity to innovate and adapt. By continuing to invest in research and development, improving infrastructure, and addressing economic and technical challenges, we can transition towards a more sustainable and environmentally friendly energy system.

Where in paragraph 1 does the following sentence best fit?
The shift towards renewable energy is seen as a necessary response to the global energy crisis.
