Answer 2

Answer:

There is heavy competition for work among the farm labourers because labour is one of the necessary factor for production. Only the large farmers hire them and for limited days like harvesting seasons. They have to regularly look for work to live. So, whenever there is work available the labourers agree to do work for lower wages.
