Read the following passage about The Elderly in Multicultural Societies: Challenges and Opportunities 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.

In multicultural societies, elderly individuals face unique challenges and important opportunities. As communities diversify rapidly, traditional support systems are constantly evolving. Seniors often navigate unfamiliar cultural environments while facing significant language barriers that lead to social isolation. These persistent obstacles frequently prevent full access to essential healthcare services or meaningful community participation. Fortunately, innovative local organizations address these critical issues by offering comprehensive translation services and culturally sensitive care options.

Technology presents both remarkable benefits and considerable difficulties for elderly individuals from various cultural backgrounds. Digital tools effectively connect seniors with distant family members globally, yet many older adults struggle substantially with these new communication methods. Recent research shows approximately 65% of elderly immigrants experience digital exclusion compared to native-born seniors. In response, numerous community centers have successfully established specialized technology workshops for older adults from diverse backgrounds, helping them maintain vital connections with overseas relatives and friends.

Cultural differences significantly impact elderly care approaches across communities. In collectivist cultures, elderly family members traditionally live with their children, while Western societies typically emphasize personal independence. This fundamental divergence creates tension when immigrant families attempt to adapt to new societal norms. However, vibrant multicultural environments provide valuable opportunities for exchanging diverse perspectives on aging. Many communities benefit tremendously from adopting hybrid approaches blending traditional cultural practices with modern care techniques, creating more comprehensive support systems.

Economic aspects of aging in multicultural contexts matter significantly for overall wellbeing. Elderly immigrants frequently face severe financial hardships due to limited retirement savings and persistent employment discrimination throughout their lives. Some progressive governments implement supportive policies addressing these vulnerable individuals' unique needs. Certain forward-thinking regions offer specialized employment programs for seniors with diverse cultural backgrounds, recognizing their valuable skills and extensive life experiences. Additionally, creative intergenerational initiatives connecting elderly immigrants with younger community members effectively foster mutual understanding and practical support, successfully transforming demographic challenges into meaningful community enrichment opportunities.

In which paragraph does the writer mention economic challenges and supportive initiatives for elderly immigrants?

Read the following 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 31 to 40.

A New Capital

When Pakistan was established as a new state in 1947, Karachi initially served as its capital. However, maintaining Karachi as the capital proved to be a challenge due to several disadvantages, such as its climate and the condition of the existing infrastructure. Rather than attempting to improve these issues, the government opted to create a completely new capital city. In 1959, a commission was formed to explore potential locations for this new capital. Dr. Doxiadis, a renowned architect and city planner, was appointed as the chief advisor to the commission.

Dr. Doxiadis and his team explored several possible sites for the new capital, considering both geographical and environmental factors. After a thorough evaluation, they narrowed the options down to two locations: one just outside Karachi and the other located north of Rawalpindi. Both sites had their own sets of advantages and drawbacks, making the decision a complex one.

The final choice was made after carefully considering a range of factors such as transportation, water availability, economic implications, and national interests. Ultimately, the area north of Rawalpindi was selected. On February 24, 1960, the new capital city was named Islamabad, and a comprehensive master plan for its development was created. The plan divided the area into three distinct sections: Islamabad itself, neighboring Rawalpindi, and a national park.

Each section was designed to serve a specific purpose. (I) Islamabad would function as the country’s political and cultural center, meeting the administrative needs of the nation. (II) Rawalpindi, located nearby, would continue as the regional hub for industry and commerce. (III) The national park area was intended to provide space for education, recreation, and agriculture, enhancing the quality of life for residents. (IV)

Today, Islamabad is a vibrant city with a population of around 1 million people. Known for its clean and healthy environment, it offers a pollution-free atmosphere, abundant water resources, and ample green spaces. Tree-lined streets, elegant public buildings, and well-planned shopping centers make the city a model of successful urban planning. With its efficient design and flourishing urban life, Islamabad stands as a prime example of well-executed city planning and growth.

Which of the following is NOT a factor considered when choosing the new capital city?
