The primary task of a university is to educate. But to teach well, professors must be informed about new developments in their disciplines, and that requires research. Yet many universities cannot afford to support faculty research adequately. So a lack of funds for research adversely affects the degree to which a university can fulfill its central mission. Which one of the following most accurately expresses the conclusion of the argument? ['Lack of financial support for faculty research is the root of ineffective teaching at universities.', 'In order to be able to teach well, university professors must conduct research.', 'Effective teaching is the primary mission of a university.', 'Lack of funds for research reduces the quality of education a university provides.']
