Non-IMPORTED agreements were a series of commercial restrictions adopted by American colonists to protest British revenue policies prior to the American Revolution.
Neutrality. (Assuming that's one of your options)
If there is a higher tariff on British goods, then people would not want to buy their goods because the tax if too high. If they can get something else for a lower cost, such as good from American business then they would go and buy from those business. This protects them because again people like to get the most for their buck and this lessens competition from British business.
