Read the following passage about urbanisation and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions.

URBANISATION: A GROWING PHENOMENON

     Urbanisation is the process through which cities grow, and higher populations begin to inhabit urban areas. This phenomenon has accelerated significantly over the past few decades due to various factors. One of the primary drivers is the search for better employment opportunities. In rural areas, job prospects are often limited to agriculture and small-scale industries, which might not provide sufficient income. Consequently, people migrate to cities seeking better livelihoods and living standards.

     Additionally, urban areas offer more advanced educational facilities and healthcare services compared to rural regions. Many families move to cities to provide their children with higher-quality education and greater future opportunities. Access to hospitals and specialized medical services also attracts people to urban centers, especially in countries where rural healthcare is underdeveloped.

     However, rapid urbanisation brings about several challenges. Overcrowding in cities can lead to inadequate housing, strained infrastructure, and increased pollution. The expansion of urban areas often results in the loss of green spaces and agricultural land, impacting food production and the environment. Governments and city planners must address these issues to ensure sustainable urban growth.

     Despite these challenges, urbanisation has several positive aspects. Cities are often cultural melting pots, where diverse groups of people interact, leading to vibrant communities and innovation. The concentration of resources and talents in urban areas can drive economic growth and technological advancements.

Read the following passage about Preserving Today's Soundscapes for Future Generations 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.

Sonic time capsules save today's sounds for future people. Scientists capture everyday sounds like streets, birds, and children playing in parks around the world. These recordings help us remember our world before changes. Cities are losing unique sounds as life becomes similar everywhere. Old machines, music, and natural sounds might disappear if not saved. Many important cultural sounds are already lost forever because nobody thought to record them when they still existed.

Sound collectors use microphones to record in different places. They visit forests, oceans, cities, and villages to capture soundscapes throughout different seasons and times of day. They store sounds in digital libraries for years. Museums have rooms for listening to past sounds. These experiences help people understand history in ways books cannot. Some researchers travel to remote locations to record indigenous languages and traditional ceremonies before they vanish from our collective memory.

Climate change is changing world sounds. Melting glaciers, endangered animals, and disappearing languages need saving before they're gone. Researchers believe future people will want to know how our world sounded. These capsules will be important records, like photographs. Scientists study how sounds affect human health. The sounds of nature can reduce stress and improve mental health, which makes preserving natural soundscapes even more important for future generations who may live in highly urbanized environments.

Community projects invite people to record daily sounds. Children learn to listen carefully to the world around them and identify sounds that matter to their community. Old people share recordings from their childhood. People feel emotions when listening to these collections. Artists create music using everyday recordings. These projects help communities protect special sounds for the future. Some cities now have sound preservation policies that protect unique acoustic environments just as they would protect historic buildings or natural landscapes from development.

In which paragraph does the writer mention why researchers are collecting sounds affected by climate change?
