Answer:
American Woman Suffrage Association Association supports the 15th amendment because it believed in the importance that the black vote would have for the country. The National Woman Suffrage Association did not support the 15th amendment because it only cited the legalization of the vote of black people, but it did not allow the vote of women.
Step-by-step explanation:
The 15th amendment allowed voting rights for black people who were or were not slaves before. This was a major step in US civil rights, which understood that the vote of the black population was important, in addition to treating them as citizens and establishing social equality in the population regardless of the color of its members. The American Woman Suffrage Association saw this amendment as beneficial, showing that the government was evolving in its concepts and leaving society equal, so it decided to support the amendment. The National Woman Suffrage Association, on the other hand, criticized the government for allowing black people to vote, but did not include permission to vote for women, claiming that the government, with this amendment, allowed a gender-unequal society.
