Answer:The supply of plumbers in country A is greater than the supply of plumbers in country B.
Explanation:
The state of demand and supply of labour has a great effect on wages of workers. If the supply of plumbers is grater than the number s of households demanding plumbering services the wages for the plumbers will fall because more plumbers are available for the few works available and this is the situation why plumbers in country A earn less than B though the demand in both countries are the same but they do not vary in the same proportion with their demands.
The supply of plumbers in B is not greater than A and this why B earn more.
