The right answer is:
Grant's approach allowed for black rights to be respected and it encouraged participation in the reconstruction by granting voting rights to African Americans.
Johnson's approach didn't allow for black's participation in the reconstruction.
Step-by-step explanation:
After the civil war ended the U.S. had to reintegrate both a previously enslaved population and a formerly rebellious population back into the country, however Abraham Lincoln was assassinated and Andrew Johnson became acting President. Johnson believed that the South never had a chance to secede in the first place.
He also believed African Americans should not have any role in the reconstruction of the country.
He called to establish new, all-white governments and they looked very much like the old Confederate governments they replaced. However blacks now had access to education and many primary and secondary schools as well as Black Universities were now a reality.
On the other hand Grant made sure that thee reconstruction laws and amendments that were passed granted former slaves political freedom and rights especially to vote expanding black participation in the reconstruction o the country.
