The right answers are: D competition was intense for economic control and A Countries paid taxes to each other.
Explanation:
Economic competition can affect the other country because of its supply of goods. Since the colonies trafficked supplies in routes, this dealing will be broken through the obligation of higher taxes. For example, the product of a country produces cars while the other produces carpets. If a competition between the two countries exists, the tendency is that the carpet country will have to increase tax imposition with regards to their products and the cars country will find it very expensive to buy carpets from it hence losing much money. The car country may stop the trade of cars while the other will also experience damages by looking for another country supplier of cars. If the substitute they will get could not meet the same standard as the cars they will suffer damages and growth of prices because the demand for the car country which they cannot import any longer will increase.
