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 33 to 40.

Air pollution is a significant environmental issue that affects millions of people worldwide. It results from various sources, including industrial emissions, vehicle exhaust, and the burning of fossil fuels. [I] Among the most harmful pollutants are fine particulate matter (PM2.5), carbon monoxide, sulfur dioxide, and nitrogen oxides. These pollutants not only degrade air quality but also have serious health consequences, such as respiratory diseases, cardiovascular problems, and even premature death. [II]

In major cities, traffic congestion plays a critical role in worsening air pollution. The high concentration of vehicles, particularly those running on diesel fuel, releases large amounts of pollutants into the atmosphere. [III] Additionally, industrial activities in urban areas contribute to the problem by emitting harmful gases and chemicals. [IV]

Governments and environmental organizations have been implementing various measures to combat air pollution. These include promoting the use of renewable energy, encouraging public transportation, and imposing stricter emission regulations on industries. Moreover, advancements in technology have led to the development of electric vehicles and air purification systems, which help reduce pollution levels. However, despite these efforts, achieving clean air remains a global challenge that requires cooperation from all sectors of society.

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.                                                                   

In which paragraph does the author discuss the importance of social bonds in achieving happiness?

Read the following passage about the Reimagining International Cooperation 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.

Global environmental governance is changing how countries work together. Nations now understand that pollution, climate change, and resource problems cross borders. Traditional agreements between countries are not enough anymore. New approaches include businesses, local communities, and citizen groups working with governments. This all-hands-on-deck approach helps create better solutions for our planet. Many successful projects show that when different groups cooperate, they can solve difficult environmental problems that single countries cannot fix alone.

Environmental governance faces many challenges today. [I] Political differences between nations often slow down important decisions. [II] Some countries worry that strict environmental rules might hurt their economic growth. Despite these obstacles, new technologies are helping countries monitor environmental changes better. [III] Satellite data and computer models allow scientists to track forest loss, ocean pollution, and climate patterns. [IV] This information helps leaders make smarter decisions about protecting natural resources.

The future of environmental governance depends on innovation. Digital platforms now connect environmental experts around the world instantly. Young people are bringing fresh ideas through social media campaigns and protest movements. Indigenous communities contribute valuable traditional knowledge about sustainable living practices. Financial institutions are creating new ways to fund green projects in developing countries. These combined efforts are creating a more flexible and responsive system of global cooperation that can adapt to changing environmental conditions more quickly than old-fashioned diplomatic channels.

Effective environmental governance requires balance between global standards and local solutions. While international agreements provide important frameworks, communities need freedom to implement approaches that fit their unique situations. Successful governance models respect cultural differences while maintaining scientific standards. Education plays a crucial role in building public support for environmental policies. When citizens understand environmental issues, they make better choices and hold their leaders accountable. The most promising path forward combines strong international institutions with energetic local action to create lasting environmental solutions.

The word “instantly” in paragraph 3 is OPPOSITE in meaning to _________.
