Answer:
The pharaoh required farmers to contribute their labor when crops were not in season.
Step-by-step explanation:
When there is not a season for cultivation of crops due to unavailability of water for irrigation, the farmers work for the pharaoh as a labour to make pyramids and tools in order to earn food and money for their families. But when the flooding occurs, the cultivation period started and the farmers again started working in the fields to grow different crops for food.
