Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 29 to 33.

International Women’s Day, celebrated on March 8th, is a time to honor women’s progress and advocate for real change towards gender equality. This day, rooted in a 1908 demonstration where 15,000 women in New York City stood united for equal rights, better pay, shorter hours, and voting rights, has grown into a worldwide movement. Clara Zetkin, at a meeting in 1910, suggested a special day each year to focus on women’s rights, leading to the first International Women’s Day in 1911.

Despite some beliefs that women have equal chances as men, the reality often tells a different story. Girls worldwide face more household duties than boys and are more likely to miss out on school. In many countries, equal education for both genders is not guaranteed, and many girls are married off young, which can force them to end school early, lead to early pregnancy together with other health issues, and increase the chance of domestic violence.

On International Women’s Day, people participate in activities that raise awareness and call for gender equality. Wearing purple, a color of women’s rights history, is common. It is also a day when women are celebrated with gifts and social recognition in some places.

The journey towards full gender equality continues to face challenges. Yet, women’s groups across the globe remain strong and active, with younger women and teenagers adding their voices and energy to the cause. They are organizing, speaking out, and urging a shift in how we view and act towards each other regarding gender roles.

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.
