Verified step by step guidance

1. Step 1: Understand the concept of an externality. An externality occurs when a decision causes costs or benefits to third parties who are not involved in the decision-making process.
2. Step 2: Identify whether the externality is positive or negative. A positive externality provides benefits to others, while a negative externality imposes costs or harms on others.
3. Step 3: Analyze each option to determine if it represents a positive or negative externality related to satellite usage.
4. Step 4: Recognize that improved global communication networks, enhanced weather forecasting accuracy, and greater access to educational resources are positive externalities because they benefit society.
5. Step 5: Identify that increased space debris leading to higher collision risks is a negative externality because it creates potential harm and costs for others, such as damage to satellites and space operations.
