TOPIC: Should governments impose stricter regulations on the development and use of artificial intelligence?

📝 模範解答（Agree）— 約220語

The rapid advancement of artificial intelligence has transformed industries worldwide, raising critical questions about its regulation. I firmly believe that governments should impose stricter regulations on AI development for three key reasons: job displacement, privacy concerns, and ethical risks.

Firstly, AI-driven automation poses a significant threat to employment. As machines become capable of performing tasks previously done by humans, millions of workers face the prospect of losing their livelihoods. Without proper regulation, this transition could lead to widespread economic inequality.

Secondly, the use of AI in data collection raises serious privacy concerns. Many AI systems rely on vast amounts of personal data, and without strict oversight, this information could be misused by corporations or governments for surveillance purposes.

Finally, the ethical implications of AI decision-making cannot be overlooked. Algorithmic bias in areas such as criminal justice and hiring has been well documented. Stricter regulations would ensure that AI systems are transparent and accountable.

In conclusion, given the potential for job losses, privacy violations, and ethical failures, it is essential that governments take a proactive approach to regulating artificial intelligence before these risks become unmanageable.

TOPIC: Should Japan adopt more open immigration policies to address its declining population?

📝 模範解答（Agree）— 約225語

Japan is facing an unprecedented demographic crisis, with its population declining rapidly and its workforce shrinking. I believe that Japan should adopt more open immigration policies for three compelling reasons: economic sustainability, labor shortages, and cultural enrichment.

Firstly, immigration is essential for maintaining economic growth. As the working-age population decreases, tax revenues decline while social security costs continue to rise. Welcoming skilled foreign workers would help sustain the economy and support the pension system.

Secondly, Japan is already experiencing severe labor shortages in critical sectors such as healthcare, agriculture, and construction. Without an influx of foreign workers, these industries may struggle to function, directly affecting the quality of life for Japanese citizens.

Finally, greater cultural diversity can foster innovation and creativity. Countries that embrace multiculturalism, such as Canada, have demonstrated that diverse perspectives lead to stronger problem-solving capabilities and more dynamic societies.

In conclusion, given the urgent need to sustain the economy, address workforce shortages, and promote innovation, Japan should embrace more open immigration policies while implementing integration programs to ensure a harmonious multicultural society.

TOPIC: Agree or disagree: Governments should invest more in space exploration

📝 模範解答（Agree）— 約218語

Space exploration has long been a subject of debate, with critics arguing that funds should be directed toward pressing earthly problems. However, I strongly agree that governments should invest more in this endeavor for three reasons: technological innovation, resource acquisition, and international cooperation.

Firstly, space research drives technological breakthroughs that benefit everyday life. Technologies such as GPS, water purification systems, and medical imaging were originally developed for space missions. Increased investment would accelerate the pace of such innovations.

Secondly, as Earth’s natural resources become increasingly scarce, space offers potential solutions. Asteroid mining and lunar resource extraction could provide essential minerals, reducing the environmental damage caused by terrestrial mining operations.

Finally, space exploration promotes peaceful international collaboration. Programs like the International Space Station demonstrate that nations can work together toward common scientific goals, fostering diplomatic relationships that may extend to other areas of global governance.

In conclusion, the benefits of space exploration in terms of technological progress, resource sustainability, and international diplomacy far outweigh the costs. Governments should therefore increase their commitment to this vital field of research.

TOPIC: Is social media a threat to democracy?

TOPIC: Should governments provide a universal basic income to all citizens?

📝 模範解答（Agree）— 約230語

As automation and AI continue to reshape the global economy, the concept of universal basic income has gained significant attention. I believe that governments should implement such a policy for three reasons: poverty reduction, economic stimulation, and adaptation to technological change.

Firstly, a universal basic income would serve as a safety net that effectively eliminates extreme poverty. Unlike existing welfare programs, which often fail to reach those most in need due to bureaucratic complexity, UBI ensures that every citizen has a minimum standard of living.

Secondly, providing citizens with guaranteed income would stimulate consumer spending. When people have more disposable income, they tend to spend it on goods and services, thereby boosting local businesses and driving overall economic growth.

Finally, as AI and automation increasingly displace workers across various industries, UBI would provide a crucial buffer during the transition period. Workers who lose their jobs to machines would have the financial stability needed to retrain and acquire new skills for emerging industries.

In conclusion, given its potential to alleviate poverty, stimulate economic activity, and support workers through technological transitions, universal basic income represents a forward-thinking policy that governments should seriously consider implementing.
