VI. Read the passage and then answer the questions by choosing the best option A, B, C or D.

Living environments have undergone significant changes over the past century. In the past, people often lived in rural areas or small towns, where they were closely connected to nature. Their homes were typically made of locally sourced materials like wood and stone, and many households grew their own food. The air was cleaner, and there was less noise pollution compared to today's urban environments.

Today, a large proportion of the population lives in cities. Urban living offers numerous advantages, such as access to better healthcare, education, and job opportunities. However, it also comes with challenges. City dwellers often face issues like air and noise pollution, overcrowded public transportation, and a lack of green spaces.

Nowadays, many people spend most of their time indoors, working at desks or using electronic devices for entertainment. This shift has led to concerns about physical and mental health, as a sedentary lifestyle can contribute to various health issues.

Despite the benefits of modern urban living, there is a growing movement towards creating sustainable and green living environments. This includes building eco-friendly homes, creating more parks and green spaces, and encouraging people to adopt a more active lifestyle. By combining the conveniences of modern life with the simplicity and sustainability of the past, we can create healthier and more enjoyable living environments for everyone.

Keeping our environment clean is essential for ensuring a healthy and sustainable future. One of the most effective ways to achieve this is by reducing waste. This can be done through practices such as recycling and composting. Recycling helps to convert waste materials into new products, reducing the need for raw materials and minimizing the amount of waste that ends up in landfills. Composting organic waste like food scraps and yard waste can create nutrient-rich soil for gardening. Another important practice is reducing the use of plastic. Opting for reusable bags, bottles, and containers can significantly cut down on plastic pollution. Additionally, conserving water and energy in our daily lives can contribute to a cleaner environment. Simple actions like fixing leaks, taking shorter showers, and turning off lights when not in use can make a big difference. Planting trees and maintaining green spaces are also crucial, as they help to improve air quality and provide habitats for wildlife. Lastly, educating others about the importance of environmental conservation and encouraging community clean-up efforts can amplify these efforts. By adopting these habits, we can collectively make a significant impact on keeping our environment clean and healthy for future generations.
