Which of the following is part of the Basis and Purpose of the Amateur Radio Service?

The Federal Communications Commission (FCC) defines the "Basis and Purpose" of the Amateur Radio Service in Part 97.1 of their rules. One of the primary pillars of this service is advancing the public's skills in both the technical and communication phases of the radio art. Providing personal radio communications for as many citizens as possible is the purpose of services like Citizens Band (CB) or Family Radio Service (FRS), not Amateur Radio. Furthermore, amateur radio is strictly non-commercial and not dedicated to serving specific organizations, which rules out providing communications specifically for international non-profits.
