You can check out books from home, you can research on the way to school or from school, but these are really two big assumptions, that one, you have access at home, and two, that you have access to a mobile phone, and in Philadelphia, many kids do not.
Možete gledati knjige od kuće, možete istraživati na putu  do škole ili od škole, ali tu su zapravo dvije velike pretpostavke, kako jedan, imate pristup od kuće, te dva, kako imate pristup mobitelu, a u Philadelphiji, brojna djeca nemaju.
