It is well known that many homeless people frequent public libraries as a kind of sanctuary. now, several dozen public libraries across the country have made their facilities more useful to homeless people by offering free job training programs, for adults and free activities for homeless children. while the administrators of these libraries mean well, the homeless do not pay property taxes to support the library, so these people are getting something for nothing, a dangerous practice for all concerned.

which of the following is assumed by the author of this argument?

a)none of the sales tax paid by homeless people who use the free services is used by the libraries.
b) property taxes are used predominantly to support public libraries.
