Read the following passage about the A Vision of a Harmonious Multicultural Society 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.

By 2050, our world will have undergone remarkable transformations in how different cultures coexist. The walls that once divided nations are vanishing into thin air as global citizens embrace diversity like never before. Technology will serve as the great equalizer, with translation devices making language barriers a thing of the past. In urban centers worldwide, neighborhoods will showcase architectural influences from multiple cultures, creating spaces where everyone feels at home regardless of their background. Public spaces will feature gardens with plants from different continents, symbolic of how various cultures can thrive together in one environment.

[I] Education systems will prioritize cultural literacy alongside traditional subjects. [II] Schools will teach world history from multiple perspectives rather than through a single cultural lens. [III] Students will routinely participate in virtual exchange programs, allowing them to form friendships with peers around the world without leaving their classrooms. [IV] Government policies will recognize that a harmonious multicultural society requires institutional support, with resources allocated to community centers where cultural exchange happens organically through shared meals, festivals, and collaborative art projects.

Economic systems will evolve to value diverse approaches to business and innovation. Companies will actively seek employees from varied backgrounds, recognizing that diverse teams create more innovative solutions. Traditional knowledge from indigenous communities will be respected and incorporated into sustainable development practices. The entertainment industry will produce content that authentically represents multiple cultures, moving beyond stereotypes to show the complexity within each tradition. Digital platforms will help preserve endangered languages and cultural practices through accessible archives and learning tools.

The greatest achievement of this harmonious world will be a new understanding of human identity. People will identify with multiple cultural traditions simultaneously without feeling conflicted about their loyalties. Holidays from various traditions will be celebrated collectively, creating new hybrid celebrations that honor multiple heritages. The concept of "us versus them" will gradually fade as people recognize shared values across different traditions. While challenges will remain, the dominant attitude will be one of curiosity rather than fear when encountering differences.

Which of the following is NOT mentioned as a feature of the world in 2050?

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question

Vietnam’s population is ageing quickly. In 2017, more than 10 per cent of the population will be 60 and older, and in 15-20 years the elderly will account for one third of the total population. This raises concerns about healthcare, welfare and pensions for the elderly at a time when Vietnam is focusing on economic integration and requires a large labor force. So far two solutions have been proposed: to loosen the two-child policy and to increase the retirement age to 58 for women and 62 for men. By ending the two-child policy the government expects to make up for the ageing population within the next 20 years. But its effect could be creating an uncontrollable boom in the Vietnamese population. When the government loosened the two-child policy in 2015 in a trial period, in the first 6 months of 2016 the third child birth rate increased remarkably by 7.5 per cent

Raising the retirement age has been proposed by the Ministry of Labor pending parliamentary evaluation in May 2017. While the policy is beneficial in utilizing the work experience of the elderly while creating savings in the pension budget, it also means fewer job prospects and promotion opportunities for younger generations. It is also not in the interest of all the elderly, especially the 70 per cent of Vietnam's labor force working in manual labor-intensive sectors such as agriculture, manufacturing and construction where working above the age of 50 can be dangerous and unproductive. Despite these drawbacks, raising the retirement age is still considered by policymakers as one of the key solutions to the ageing population problem in Vietnam. However, these are only temporary solutions.
