Professor: Unfortunately, pharmaceutical companies and other profit-driven institutions provide nearly all of the funding for the chemistry department' s research. Moreover, unless we can secure more funding for basic science research, it is highly unlikely that any significant advances in basic research will come out of the department. Thus, without increased funding from sources other than profit-driven institutions, the chemistry department is unlikely to gain the prestige that only achievements in basic science research confer. Which one of the following is an assumption on which the professor's argument relies? ["If the chemistry department's prestige increases substantially, then it is highly likely that the department's funding from sources other than profit-driven institutions will subsequently increase.", "The chemistry department's funding for basic science research is not likely to increase if its funding from sources other than profit-driven institutions does not increase.", 'Members of the chemistry department are unlikely to make significant advances in basic science research if the department does not forego the funding it currently receives from profit-driven institutions.', "The profit-driven institutions that currently provide almost all of the chemistry department's funding are not likely to benefit from basic scientific research."]
