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.

The word “complexity” in paragraph 3 is OPPOSITE in meaning to _________.
