What quality involves keen observation of things and events in the surroundings?

The quality that involves keen observation of things and events in the surroundings is curiosity. Curiosity drives individuals to explore and investigate their environment, prompting them to ask questions and seek understanding about the world around them. This intrinsic motivation to learn and discover enhances one's ability to notice details and recognize patterns in various situations.

While attention plays a crucial role in focusing on specific stimuli, curiosity is broader and encompasses a desire to learn and engage with diverse experiences. Intuition involves gut feelings or instincts rather than a methodical observation of surroundings. Inquisitiveness closely relates to curiosity but may imply a more systematic questioning approach rather than the spontaneous exploration that curiosity embodies. Therefore, curiosity is the primary quality associated with keen observation.
