premise: well i guess i don't know specifically except that uh for the paper that they want to recycle they do not want any newspaper um and things like candy wrappers or uh that type of thing let's see i have a list here um they don't want lunch sacks or brown envelopes uh phone books so there are you know a lot of kinds of things that they don't want but then any kind of computer paper letters uh booklets they'll even take things that are bound
hypothesis: It is hard for them to separate the good paper from the junk.
