Answer:
Logical evidence, because Warren is drawing a reasonable conclusion that segregating children is psychologically harmful.
Step-by-step explanation:
Logical evidence is when someone presents a reasonable sound argument on his claim. This conclusion is a result of serious research, taking facts into account, and even providing ample evidence to support the claim made.
In the given passage from the court ruling of Brown vs. Board of Education, Justice Warren provides logical evidence to support the claim that segregation of students based on their race not only leads to the assumption that blacks are inferior but also led to a detrimental effect on the students by making them think they are inferior. Justice Warren opines that "To separate them from others of similar age and qualifications solely because of their race generates a feeling of inferiority as to their status in the community that may affect their hearts and minds in a way unlikely ever to be undone", supporting the claim that segregation of students is more harmful than effective for everyone involved.
Thus, the correct answer is logical evidence.
