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 39: The author claims all of the following to be the benefits of rooftop gardens except______.

Read the following passage about endangered languages and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questionsfrom 23 to 30.

The Koromi trend has taken social media by storm, influencing fashion, lifestyle, and online communities worldwide. Originating in Japan, Koromi is characterized by a unique blend of gothic aesthetics, cute elements, and bold self-expression. Unlike mainstream kawaii culture, which emphasizes bright colors and cheerful themes, Koromi embraces darker shades, punk influences, and a rebellious attitude. This fusion of edginess and playfulness has resonated with many young people looking for an alternative form of self-representation.

Social media platforms like TikTok and Instagram have played a crucial role in popularizing the trend, as influencers and fashion enthusiasts share their interpretations of the Koromi style. The trend's rise is also linked to a growing appreciation for individuality and alternative fashion in contemporary youth culture.

Beyond fashion, the Koromi trend has influenced makeup styles, accessories, and even music preferences. Many followers of this aesthetic incorporate dark eyeliner, edgy clothing, and playful accessories to create a distinctive look. As more people adopt the Koromi lifestyle, brands have started releasing special collections inspired by the trend. However, some critics argue that the commercial adoption of Koromi dilutes its original meaning and turns it into a passing fad rather than a genuine subculture.

While Koromi's popularity continues to grow, it remains a niche trend compared to mainstream fashion movements. Its impact, however, is undeniable, as it encourages self-expression and challenges conventional beauty standards. Whether it will evolve into a long-lasting cultural phenomenon or fade away as another internet-driven craze remains to be seen.

In which paragraph does the writer discuss the impact of the Koromi trend on beauty standards?

Read the following passage about world festivals and mark the best answer to the questions from 11 to 18. 

     World festivals have a big impact on young people today. Festivals such as Christmas, Diwali, Halloween, and Chinese New Year are celebrated across the globe, bringing people together. Young people especially enjoy these events because they offer a chance to have fun, learn about different cultures, and develop a global mindset.

     Festivals help young people appreciate diversity. Attending a festival from another culture teaches them new traditions, food, music, and art. For example, attending the Rio Carnival or the Holi Festival of Colors can give young people an exciting experience of new cultures. They learn to respect and understand people from different backgrounds, which is important in today’s world.

     Another impact is that festivals allow young people to express themselves creatively. Many festivals include costumes, dances, and music that encourage self-expression. For instance, during Halloween or a music festival like Coachella, young people often wear creative outfits or costumes that reflect their personalities. This makes them feel confident and allows them to experiment with new styles.

    Festivals also offer opportunities for young people to connect with others. Meeting people at festivals, whether in person or online, helps them build friendships and networks. Social media plays a big role in this, as many young people post about their experiences, spreading awareness of the festivals they attend.

     Overall, world festivals provide many learning and social experiences for young people, helping them grow into more open-minded and creative individuals.
