Directions: Read the following passage and answer the given question. China's Gross Domestic Product (GDP) is one of the largest in the world, reflecting its position as a global economic powerhouse. Currently, China has the second-largest GDP, valued at over $17 trillion, trailing only the United States. This growth has been driven by industrial development, strong exports, and increasing technological innovation. For many years, China's economy was centered on manufacturing, earning it the title "the factory of the world." However, recent trends show a shift towards services and domestic consumption, with e-commerce and technology playing key roles in driving growth. Companies like Alibaba and Huawei highlight this transition. Despite its rapid expansion, China faces challenges such as an ageing population, environmental concerns, and trade tensions with other nations. To address these issues, the government is focusing on green energy, innovation, and infrastructure development. China's GDP growth remains steady, ensuring its influence on the global economy continues to grow. What is a likely reason for China's focus on green energy and innovation?

### Concept & Logic This is a direct factual retrieval question from the reading comprehension passage. We must locate the keywords ("green energy and innovation") to identify their cause-and-effect relationship in the text. ### Step-by-Step Solution * **Scan for Keywords**: Look for the exact phrase "green energy" in the passage. * **Locate the Context**: We find this in paragraph 3: "Despite its rapid expansion, China faces challenges such as an ageing population, environmental concerns... To address these issues, the government is focusing on green energy, innovation, and infrastructure development." * **Match the Option**: The text explicitly states that focusing on green energy and innovation is a direct response "To address these issues" (which include environmental concerns). * **Eliminate Alternatives**: None of the other options (agriculture, foreign investments, decreasing GDP, reducing domestic consumption) are mentioned as reasons for adopting green energy. ### Exam Strategy & Shortcut For "reason" or "cause" based questions, always find the specific keyword in the text and read the sentence immediately preceding it. The answer is almost always explicitly stated right there. ### Common Pitfall A common pitfall is overthinking the question and relying on outside general knowledge rather than strictly answering based on the provided text. ### Final Answer Therefore, the correct answer is **To address challenges like environmental concerns and slowing growth.**
