How can supranationalism challenge sovereignty?

Supranationalism in my view (not a scholar) is a superior category in the international relations system. Supranationalism takes simple inter country relations between countries and applies them to various countries in an unified manner. Should one country decide it is not in their interest to develop a relationship with another entity, it will not develop it. In the same way, should a country decide it is in their interest to enter in a series of treaties, the country can decide to enter and follow all the rules the treaties enforce.

Explanation:

the correct answers are: 1) lay and collect taxes and duties; 2) pay debts; 5) borrow money;   6) regulate commerce with foreign nations.

article 1, section 8. refers to the powers of congress. according to the united states constitution: “the congress shall have the power to lay and collect taxes, duties, imposts, and excises, to pay the debts and provide for the common defense and general welfare of the united states.”

the answer would be cities along the east coast.
