Read the following passage about Artificial Intelligence 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.

Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are designed to think, learn, and adapt. AI is applied in various fields, including healthcare, education, transportation, and entertainment. Technologies such as machine learning, natural language processing, and robotics enable AI systems to perform tasks like diagnosing diseases, personalizing education, and even driving autonomous vehicles.

One significant benefit of AI is its ability to enhance efficiency and accuracy. For example, AI-powered systems can analyze vast amounts of data faster than humans, identifying patterns and trends that might otherwise go unnoticed. In healthcare, this means earlier diagnosis and improved treatment plans. In transportation, AI contributes to safer roads with the development of self-driving cars.

Despite these advantages, AI poses several challenges. Concerns include ethical issues, such as bias in algorithms, and the potential loss of jobs due to automation. Cybersecurity risks are also heightened as AI systems become more integrated into critical infrastructure. Addressing these challenges requires transparency, regulation, and collaboration among stakeholders.

To maximize its benefits, society must approach AI development responsibly. Governments, private organizations, and researchers are working together to create ethical guidelines and ensure that AI serves humanity’s best interests. As AI continues to evolve, it holds the promise of transforming the way we live and work.

In which paragraph does the writer discuss the challenges posed by AI?

Read the following passage about the Reimagining International Cooperation 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.

Global environmental governance is changing how countries work together. Nations now understand that pollution, climate change, and resource problems cross borders. Traditional agreements between countries are not enough anymore. New approaches include businesses, local communities, and citizen groups working with governments. This all-hands-on-deck approach helps create better solutions for our planet. Many successful projects show that when different groups cooperate, they can solve difficult environmental problems that single countries cannot fix alone.

Environmental governance faces many challenges today. [I] Political differences between nations often slow down important decisions. [II] Some countries worry that strict environmental rules might hurt their economic growth. Despite these obstacles, new technologies are helping countries monitor environmental changes better. [III] Satellite data and computer models allow scientists to track forest loss, ocean pollution, and climate patterns. [IV] This information helps leaders make smarter decisions about protecting natural resources.

The future of environmental governance depends on innovation. Digital platforms now connect environmental experts around the world instantly. Young people are bringing fresh ideas through social media campaigns and protest movements. Indigenous communities contribute valuable traditional knowledge about sustainable living practices. Financial institutions are creating new ways to fund green projects in developing countries. These combined efforts are creating a more flexible and responsive system of global cooperation that can adapt to changing environmental conditions more quickly than old-fashioned diplomatic channels.

Effective environmental governance requires balance between global standards and local solutions. While international agreements provide important frameworks, communities need freedom to implement approaches that fit their unique situations. Successful governance models respect cultural differences while maintaining scientific standards. Education plays a crucial role in building public support for environmental policies. When citizens understand environmental issues, they make better choices and hold their leaders accountable. The most promising path forward combines strong international institutions with energetic local action to create lasting environmental solutions.
