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).

Read the passage 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 7 to 14.
The concept of project farming, where farmers come together to collaborate on large-scale agricultural projects, has gained significant traction, and modern technology keeps this collaboration on track. Advanced technologies such as GPS, sensors, drones, and data analytics are used to optimise agricultural practices. Additionally, the collected real- time data on soil conditions, weather patterns, and plant growth enables farmers to accelerate the decision-making process that maximises productivity while minimising resource wastage.
GPS technology allows farmers to precisely map out their fields and create customised planting plans. This ensures that seeds are sown at optimal locations based on soil characteristics and previous yield data. By avoiding areas with poor fertility, farmers can increase their overall crop yield. Camera traps provide advance warnings of insects, so farmers do not have to treat the whole field. This, therefore, helps curb chemical runoff and save money for every party involved in the project.
Technology also plays a vital role in optimising irrigation practices for sustainable agriculture. Specialised equipment reports dryness hour by hour, and weather apps forecast rain for the week ahead. Automated valves give each zone exactly the water it needs and pause when clouds are approaching. This cuts pumping costs and protects groundwater while keeping the crop healthy. On dry continents, such savings keep projects economically viable.
The digital trail does not stop at the farm gate. Cloud platforms let project farmers, processors, and truck drivers input harvest weights, storage temperatures, and delivery times the moment they change, while blockchain records freeze each entry so customers can trust it. Analytic tools combine seasons of records to forecast demand, spot price opportunities, and mark weak points in the workflow. This allows project farmers to anticipate market demand, exploit resource allocation, and plan for potential challenges.
