Answer:
3) reconciliation after the war to heal the nation's wounds
Explanation:
With the country divided over slavery, the only way to move foward as a union would be to maintain neutral relations within the country. America needed to heal after the great loss of many lives in the Civil War. Rather than remain divided, the country needed to work together and heal as one.
Such parties would create regionalism in the country and sacrifice the unity of the country.
Explanation:
Washington understood that in a federation like Us there was an importance of political unity to keep the federation and its different states to stick together.
Regional parties could take care of the needs of their own specific region but it would also mean that the parties would not care for others and might sacrifice their interests.
This would result in discord and even could lead to the partition of the country which Washington did not want so he was against the idea of regional parties.
