Which excerpt from the passage “Equal Justice Under Law: Thurgood Marshall” most effectively illustrates Marshall’s view that segregation was unconstitutional? "He wanted to persuade the court that segregation was itself wrong, that the whole idea of “separate but equal” was fundamentally unjust."

“In 1896, in the case of Plessy v. Ferguson, the Court had ruled that segregation was allowed under the Constitution: the facilities for black Americans, the Court said, simply had to be as good as those for whites—'separate but equal.’”

Marshall repeated the argument he had made in South Carolina. Segregation hurt black children. There was no reason for it, other than to keep one race up and the other down."

“…while Marshall earned high grades in college, the all-white law school of the University of Maryland refused to admit him. (Maryland had no law school for African Americans.)”
