Read the following passage about Unconventional Teachers Who Changed Lives 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.

Traditional education focuses on textbooks, but some teachers go beyond these limitations. Mrs. Rodriguez transformed her classroom into a living laboratory. Her students conducted experiments with plants and simple machines. She believed hands-on learning creates deeper understanding than reading alone. When asked why she taught differently, she replied, "I want students to fall in love with discovery." Her methods helped struggling students improve and develop passion for science.

Mr. Jackson abandoned lectures for storytelling and role-playing. His students experienced history by acting out important moments. This approach made history come alive and helped them remember key information. One student said, "Before Mr. Jackson's class, I thought history was boring, but he showed us it's fascinating." He took classes to historical sites and invited veterans to share experiences. These connections helped students understand how past shapes our present.

In a remote village, Ms. Chen taught English without proper textbooks. She created materials using newspapers and song lyrics. Despite limited resources, her students achieved remarkable results through her dedication. "Learning should be joyful, not painful," she told questioning parents. Ms. Chen organized conversation clubs and pen pal exchanges. These activities gave students practical language skills and confidence to use English in real situations.

Coach Williams was a life mentor who taught valuable lessons through sports. He focused on teamwork and fair play rather than winning. Students who struggled academically often excelled in his class. "The playing field is where children learn who they truly are," he explained. He created inclusive activities for all students regardless of athletic ability. Many former students credit him with teaching life skills like resilience and cooperation that helped them succeed after graduation.

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.

Which of the following is NOT mentioned as a challenge faced by elderly immigrants?

Read the following passage about urbanisation and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions.

URBANISATION: A GROWING PHENOMENON

     Urbanisation is the process through which cities grow, and higher populations begin to inhabit urban areas. This phenomenon has accelerated significantly over the past few decades due to various factors. One of the primary drivers is the search for better employment opportunities. In rural areas, job prospects are often limited to agriculture and small-scale industries, which might not provide sufficient income. Consequently, people migrate to cities seeking better livelihoods and living standards.

     Additionally, urban areas offer more advanced educational facilities and healthcare services compared to rural regions. Many families move to cities to provide their children with higher-quality education and greater future opportunities. Access to hospitals and specialized medical services also attracts people to urban centers, especially in countries where rural healthcare is underdeveloped.

     However, rapid urbanisation brings about several challenges. Overcrowding in cities can lead to inadequate housing, strained infrastructure, and increased pollution. The expansion of urban areas often results in the loss of green spaces and agricultural land, impacting food production and the environment. Governments and city planners must address these issues to ensure sustainable urban growth.

     Despite these challenges, urbanisation has several positive aspects. Cities are often cultural melting pots, where diverse groups of people interact, leading to vibrant communities and innovation. The concentration of resources and talents in urban areas can drive economic growth and technological advancements.
