There would be no separation between one country’s economy and another’s if the entire world

the world has different currency because we all have different forms of money , US has $ , mexico has pesos , so the answer would be A:shared the same currency .

The correct answer is: there would be no separation between one country's economy and another's if the entire world shared the same currency. This would make the economic world system a more united one, since all of the countries would have the same currency, and therefore the same currency risk in the international trade. It would certainly level all of the different countries' economies together, because different countries would not be able to use their currency exchange as a way to sell their goods for a higher or lower price in the global market. It would create a sense of community within the different economies around the world, in the same way that the euro joined the different European economies.

world war i had a devastating effect on german-americans and their cultural heritage. up until that point   german-americans, as a group, had been spared much of the discrimination, abuse, rejection, collective mistrust experienced by so many different racial and ethnic groups in the history of the united states. indeed, over the years, they had been viewed as a well integrated and esteemed part of american society. all of this change with the outbreak of war.
