Question

Primary sources __________. interpret and analyze other primary sources analyze computer and Internet sources provide firsthand testimony or direct evidence can only be found in public and university libraries

Answer 1

Primary sources "provide firsthand testimony or direct evidence". In contrast, secondary sources interpret and analyze other primary sources by providing some kind of comment on them. Many primary sources can be found in public and university libraries, but these are not the only locations - for example, some may be owned by private owners.
