AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Indentured labour was a system where labourers were hired under contracts (bonds) to work for an employer. Workers were promised return travel to India after completing five years on their employer's plantation.

The question has two parts in one: (1) define the system, (2) state what was promised. Both must be addressed in one line. The key promise from the passage is "return travel to India after five years" — mention this explicitly. Do not confuse with false promises made by agents; the question asks about the contract promise.
