The bachelor of arts degree provides a traditional liberal arts experience through a balanced course of study in the arts , humanities , foreign language , social and natural sciences . The system also provides access to reference and citation information , links to on-line data , electronic journal articles , and other on-line information . This provides a way for two parties to establish a shared secret key that only those two parties know - even though they are communicating over an insecure channel . TAFI also provides the queuing of reports , enabling a repair attendant to work on several customer troubles simultaneously , and it also provides on line reference tools . In its oversight role , the U.S. General Accounting Office ( GAO ) , a part of the legislative branch , provides Congress with objective reviews of agency programs , together with recommendations for strategic intervention .
