hi there,
I can't find the complete question you have posted here but i would answer the bit i can see to the best of my knowledge.
Answer:
Sweden is a member of the European Union.
Explanation:
Sweden belongs to the European Union but the Euro currency isn't a medium of exchange there as a result of the country not meeting the requirements needed to be able to use the Euro currency.
According to a 1994 Treaty of Accession, Sweden was able to join the eurozone once the states meet the conditions set. Owing to this treaty, Sweden refused to enter into a certain membership criteria which it must have had for 2 years at least before being able to use the euro as a medium of exchange. The refusal of sweden to agree to the ERM II membership has also helped the swedish krona stay at an exchange value that is not more than ±2.5% of the Euro
Cheers.
