Explanation:

- Statement 1: The service sector is indeed a significant driver of economic development across various nations. It contributes substantially to GDP and employment in many countries, often more than the agriculture and industrial sectors.

- Statement 2: China's growth is primarily fueled by the manufacturing sector, which is a global powerhouse. However, in recent years, the service sector has also been growing and contributing significantly to China's GDP.

- Option 1: Both statements are correct. The service sector is a development driver globally, and China's growth includes contributions from both manufacturing and services.

- Option 2: Both statements are incorrect. This option doesn't hold as both statements have elements of truth.

- Option 3: This suggests the global service sector is key, but not in China. It misses the mark as China's service sector is growing in importance.

- Option 4: This implies the opposite of the provided facts, as both sectors contribute to development.
