Final answer:
The term "unsupervised learning" in the passage means "independent learning" because the excerpt mentions that working with others in a group is a form of peer-to-peer learning where each member's strengths and weaknesses are utilized. However, individuals are still required to complete their work independently.
Step-by-step explanation:
The context clue that helps determine that the term "unsupervised learning" in the excerpt means "independent learning" is the phrase "peer-to-peer learning".
The passage states that working with others in a group helps in solving exercises, but the answers and work must be done individually. This implies that the learning is independent and not supervised by an instructor or authority figure.
