Answer:
Congress could not regulate interstate trade is the correct answer.
Step-by-step explanation:
The articles of confederation was the first constitution of United States and was prepared when US needed a kind of organization for holding states together and help them to make stronger economy. The articles set up continental congress at federal level and there was no provision for executive and judicial branches. the states were given more rights. The strength of Articles was that it gave made congress the highest power in the nation to declare war, making treaties and operate post offices. All the issues between states and territories were to be dealt by the congress. The major weakness of the congress was that it didn't give much power to congress. It allowed the congress to pass the laws but the power to enforce laws was not provided, without a court system or executive leader it was not possible to enforce laws. and unanimous decision for amending the articles was also its weakness. It also couldn't control the interstate trade.
