How you believe the yellow fever epidemic started?

I believe the epidemic of yellow fever started because lack of sanitation and poor medical care. People did not know correct sanitation issues and they had not yet discovered germs and how they spread. The doctors were not so great (don't get me wrong sometimes they helped). Doctors did not have right tools and medicine to cure patients.

Hope this will help someone! ;)

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.”
