PLEASE IT'S URGENT!!

Answer 1

because they both have so many work to do but their is less amount of workers to so do they demand for services

Answer 2

When there will be development in primary and secondary sector, landlord, capitalists etc will demand more labor to enforce more manpower in that specific work in order to get more and more profits in future. So all these circumstances will increase the demand of service
