Read the following passage about urbanization 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.
[I] Urbanization refers to the increasing population shift from rural to urban areas, resulting in the growth of cities and metropolitan regions (Hall, 2014). [II] This phenomenon is driven by various factors, including economic opportunities, improved living standards, and social amenities available in urban centers. [III] As a result, urbanization significantly impacts both individuals and communities, leading to a range of benefits and challenges (Davis, 2016). [IV]
One of the primary advantages of urbanization is the economic growth it fosters. Cities often provide a plethora of job opportunities, attracting individuals seeking better employment and higher incomes. In urban areas, businesses flourish due to increased demand for goods and services, leading to enhanced economic productivity. Moreover, urbanization encourages innovation and technological advancements, as a dense concentration of people often fosters creativity and collaboration (Florida, 2017).
However, urbanization also presents significant challenges. Rapid population growth in cities can lead to overcrowding, straining public services such as transportation, healthcare, and education. Many urban areas struggle to provide adequate housing, resulting in the proliferation of informal settlements and slums. According to the United Nations (2018), nearly one billion people live in slums, lacking access to basic services. They also face adverse living conditions. This situation exacerbates social inequality and can lead to increased crime rates and health issues.
To address the challenges of urbanization, sustainable urban planning is essential. Governments and urban planners must prioritize creating inclusive, well-connected cities that provide access to essential services for all residents. Strategies such as developing affordable housing, enhancing public transport systems, and promoting green spaces can help improve the quality of life in urban areas while mitigating the negative impacts of urbanization (World Bank, 2019).

Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.
The explosion in mobile phone use around the world has made some health professionals worrieSome doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.
On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.
What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.
As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.
