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).
