Read the following passage about green living 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

          Green living refers to a lifestyle that promotes sustainability and environmental consciousness. This way of life encourages individuals to make choices that reduce their carbon footprint and conserve natural resources. Practices such as recycling, using renewable energy sources, and reducing waste are fundamental aspects of green living. By adopting these practices, individuals can contribute to the preservation of the environment and promote a healthier planet for future generations.

          One significant component of green living is the use of renewable energy sources. Solar, wind, and hydroelectric power are examples of renewable energy that can replace fossil fuels. Using renewable energy reduces greenhouse gas emissions and dependence on non-renewable resources. Additionally, renewable energy sources are often more sustainable and have less impact on the environment.

          Another important aspect of green living is sustainable consumption. This involves choosing products that are environmentally friendly and responsibly sourced. For example, buying locally produced food reduces the carbon footprint associated with transportation. Moreover, opting for products made from recycled materials helps conserve resources and reduce waste.

          Green living also emphasizes the importance of conserving water and energy. Simple actions such as turning off lights when not in use, fixing leaks, and using energy-efficient appliances can significantly reduce energy and water consumption. These practices not only benefit the environment but also save money on utility bills.

          Education and awareness play a crucial role in promoting green living. By educating individuals about the benefits of sustainable practices and how to implement them, communities can foster a culture of environmental responsibility. Awareness campaigns, workshops, and educational programs are effective ways to encourage people to adopt green living practices.

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.
