Answer: Colin's evidence is not relevant to his claim because it is about flying drones being a sport, not about privacy issues.
Step-by-step explanation: Colin's evidence is not related to his main claim, that is to say the assertion that drones do not invade people's privacy. Instead of focusing on providing evidence that supports the idea that drones do not affect people's privacy negatively, Colin offers evidence related to the thought that flying drones is a sport by stating that coordination and technical skills are necessary to fly drones. Therefore, it can be said that his argument lacks strength because it has not been properly supported.
