How did learning to read affect douglass's feelings about being a slave and why

reading angered him in a way because many of the books he read showed how his people became slaves. for example, they were taken out of their homes and brought to america to become slaves. (I forgot what book it was, but i'm sure you can figure it out)

a. theta waves. this is because the person is in a light sleep which means the brain waves would show these kind of waves.

i beleive that d is the right answer
