Adolf Hitler lead the Holocaust so the answer would be the same for both questions. The answer to those is between five and six million Jews died during the Holocaust. It is impossible to know how many Jews died exactly though.
The correct answer is C) A slave was not a citizen but rather the property of an owner.
The Dred Scott vs. Sandford case revolved around the claims of Dred Scott, a black man who was a slave. This man argued that he should be free, as his owner brought him into the Illnois territory were slavery was prohibited. Essentially, Scott argued that his living in this territory should make him free.
However, the Supreme Court ruled against Scott. The majority opinion discussed how slaves are property and that they have no rights in which white men need to respect. This controversial case caused a huge division in American society.
