Answer:
Navigation Acts
Step-by-step explanation:
Navigation Acts prevented the colonies from shipping any goods anywhere without first stopping in an English port to have their cargoes loaded and unloaded; resulting in providing work for English dockworkers, stevedores, and longshoremen; and also an opportunity to regulate and tax, what was being shipped.
The Navigation Acts only benefited England. The Acts added costs to all the items that the colonies had wanted to import. Instead of the prices being controlled by competition with other importers English merchants could charge what ever the market could support.
