Consider the following pairs regarding Satellite-Based Communication ...
1. Geostationary Earth orbit (GEO) - Correctly matched. Satellites in this orbit remain fixed relative to a specific point on Earth, providing consistent communication with that region.
2. Medium Earth orbit (MEO) - Incorrectly matched. Satellites in MEO do not necessarily provide higher bandwidth compared to GEO satellites. They typically offer a balance between coverage area and latency, often used for GPS and some communications.
3. Highly elliptical orbit (HEO) - Correctly matched. Satellites in this orbit are used for high-latitude regions and experience varying altitudes, making them suitable for covering polar areas.
4. Artificial Intelligence Preparedness Index (AIPI) - Incorrectly matched. The AIPI evaluates countries based on their digital infrastructure, human capital, labor policies, innovation, integration, and regulation, not on natural resources and economic policies.
Pairs 1 and 3 are correctly matched. Thus, the correct answer is Option B: Only two pairs.
