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 following passage about the Koromi trend 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]. If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. [II]. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. [III]. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand-the last thing you want to do is offend someone with any ignorant, boorish behavior. [IV]. Here’s how to be polite in different countries.
When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.
In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.
Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.

Read the following passage about generation gap 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] The generation gap refers to the differences in attitudes, values, and beliefs between older and younger generations. [II] With rapid advancements in technology and shifting societal norms, the generation gap has become more apparent. [III] As younger generations grow up with modern technology and global connectivity, they frequently experience a world vastly different from that of their parents and grandparents. [IV]
One of the key reasons behind the generation gap is the rapid pace of technological change. Older generations, who grew up in a world without the internet, smartphones, or social media, often find it difficult to relate to the digital lifestyles of younger people. On the other hand, younger generations have been exposed to technology from a young age, shaping their values and communication styles. Additionally, differences in social values, such as views on work, family, and personal freedom, also contribute to the gap. These differing experiences create misunderstandings and a lack of common ground between generations.
The consequences of the generation gap can be significant, especially in family dynamics and workplaces. In families, the divide can lead to conflicts between parents and children, as each generation struggles to understand the other’s worldview. In the workplace, generational differences may affect teamwork, communication, and productivity. Younger employees may prioritize flexibility and innovation, while older generations may value stability and traditional work ethics. These differences can lead to friction, decreased collaboration, and a sense of alienation among coworkers.
To bridge the generation gap, open communication and mutual understanding are essential. Both older and younger generations need to be open to learning from each other and appreciating different perspectives. For instance, older generations can offer wisdom and experience, while younger generations can share their knowledge of technology and new trends. Encouraging intergenerational dialogue through family discussions, mentoring programs, or team-building activities in the workplace can help foster respect and collaboration. By recognizing and embracing their differences, both generations can work together to create a more harmonious society.
