Answer:
U.S supreme court
Explanation:
Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), was a landmark decision of the U.S. Supreme Court in which the Court held that the Constitution of the United States was not meant to include American citizenship for black people, regardless of whether they were enslaved or free, and therefore the rights and privileges it confers upon American citizens could not apply to them.
A. it explains how the executive branch is set up.
Yes, this is true. In brown vs board of education of Topeka, the case got a legal victory due to the fact that it wasn't separate but equal, as the girl had to walk 20 blocks - a few miles - to get to her school, as she attends a black school. white people were able to get to schools near them, which is totally unfair. so the supreme court said 'separate but equal' is unconstitutional.
