Commentator: In academic scholarship, sources are always cited, and methodology and theoretical assumptions are set out, so as to allow critical study, replication, and expansion of scholarship. In open-source software, the code in which the program is written can be viewed and modified by individual users for their purposes without getting permission from the producer or paying a fee. In contrast, the code of proprietary software is kept secret, and modifications can be made only by the producer, for a fee. This shows that open-source software better matches the values embodied in academic scholarship, and since scholarship is central to the mission of universities, universities should use only open-source software. The commentator's reasoning most closely conforms to which one of the following principles? ['Universities should use the type of software technology that is least expensive, as long as that type of software technology is adequate for the purposes of academic scholarship.', 'A university should not pursue any activity that would block the achievement of the goals of academic scholarship at that university.', 'The form of software technology that best matches the values embodied in the activities that are central to the mission of universities is the form of software technology that is most efficient for universities to use.', 'Universities should choose the type of software technology that best matches the values embodied in the activities that are central to the mission of universities.']
