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:

            For many people who live in cities, parks are an important part of the landscape. They provide a place for people to relax and play sports, as well as a refuge from the often harsh environment of a city. What people often overlook is that parks also provide considerable environmental benefits.

            One benefit of parks is that plants absorb carbon dioxide - a key pollutant - and emit oxygen, which humans need to breathe. According to one study, an acre of trees can absorb the same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parks also make cities cooler. Scientists have long noted what is called the Urban Heat Island Effect: building materials such as metal, concrete, and asphalt absorb much more of the sun’s heat and release it much more quickly than organic surfaces like trees and grass. Because city landscapes contain so much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to mitigate the Urban Heat Island Effect.

            Unfortunately, many cities cannot easily create more parks because most land is already being used for buildings, roads, parking lots, and other essential parts of the urban environment. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are very complex and require complicated engineering, but others are simple container gardens that anyone can create with the investment of a few hundred dollars and a few hours of work.

            Rooftop gardens provide many of the same benefits as other urban park and garden spaces, but without taking up the much-needed land. Like parks, rooftop gardens help to replace carbon dioxide in the air with nourishing oxygen. They also help to lessen the Urban Heat Island Effect, which can save people money.

            In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help hold in the heat that materials like brick and concrete radiate so quickly, leading to savings on heating bills. Rooftop vegetable and herb gardens can also provide fresh food for city dwellers, saving them money and making their diets healthier. Rooftop gardens are not only something everyone can enjoy, they are also a smart environmental investment.

Question 40: According to the author, one advantage that rooftop gardens have over parks is that they______.

Thông thường để xử lý, khử khuẩn nước hồ bơi, người ta sử dụng thiết bị lọc và hóa chất xử lý nước như chlorine. Đây là phương pháp phổ biến, dễ thực hiện và khá hiệu quả. Song nhược điểm của nó là nếu sử dụng quá lượng chlorine cho phép sẽ gây nên các phản ứng ngược, ảnh hưởng đến chất lượng nước và sức khỏe người bơi.

Các nhà khoa học đã nghiên cứu và ứng dụng thành công, ứng dụng phương pháp điện phân muối ăn để tạo ra nguồn khí clo để xử lý nước bể bơi. Đây là phương pháp được đánh giá là hiệu quả vượt trội và thân thiện với môi trường so với các phương pháp xử lý nước bằng hóa chất truyền thống. Quá trình xử lý nước bể bởi bằng điện phân muối ăn là một chu trình hoàn toàn khép kín. Quá trình thực hiện: Hòa tan muối bể bơi vào nước bể bơi rồi để tan sau một ngày. Khởi động hệ thống lọc nước như sau: Bơm nước cần xử lý qua máy điện phân. Tại đây dung dịch nước muối đã trải qua trình điện phân để tạo ra khí clo, khí hiđro và xút. Những sản phẩm không cần thiết cho quá trình làm sạch sẽ được đưa ra ngoài, chỉ có dung dịch nước đã qua xử lý và khí clo được bơm ngược trở lại bể bơi.

Nhận định nào dưới đây sai khi nói về quá trình xử lý nước bể bơi bằng phương pháp điện phân dung dịch nước muối?

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.
