Read the following excerpt from Narrative of the Life of Fredrick Douglass, by Fredrick Douglass and answer the question that follows.

The plan which I adopted, and the one by which I was most successful, was that of making friends of all the little white boys whom I met in the street. As many of these as I could, I converted into teachers. With their kindly aid, obtained at different times and in different places, I finally succeeded in learning to read. When I was sent of errands, I always took my book with me, and by doing one part of my errand quickly, I found time to get a lesson before my return. I used also to carry bread with me, enough of which was always in the house, and to which I was always welcome; for I was much better off in this regard than many of the poor white children in our neighborhood. This bread I used to bestow upon the hungry little urchins, who, in return, would give me that more valuable bread of knowledge. I am strongly tempted to give the names of two or three of those little boys, as a testimonial of the gratitude and affection I bear them; but prudence forbids;—not that it would injure me, but it might embarrass them; for it is almost an unpardonable offence to teach slaves to read in this Christian country.

Which of the following best summarizes the passages?
The white boys in his neighborhood taught him to read in exchange for pieces of bread.
It was against the rules to teach slaves to read in white Christian country.
Frederick Douglass was wealthy while the white boys were poor.
Frederick Douglass couldn’t go to school because he had too many errands to do.
