In recent years American society has become increasingly dependent on its universities to find solutions to its major problems. It is the universities that have been charged with the principal responsibility for developing the expertise to place men on the moon; for dealing with our urban problems, and with our deteriorating environment; for developing the means to feed the world’s rapidly increasing population. The effort involved in meeting these demands presents its own problems. In addition, this concentration on the creation of new knowledge significantly impinges on the universities’ efforts to perform their other principal functions, the transmission and interpretation of knowledge -- the imparting of the heritage of the past and the preparing of the next generation to carry it forward.
With regard to this, perhaps their most traditionally sanctioned task, colleges and universities today find themselves in a serious bind generally.
A. the government has stopped giving public institutions as much financial support as it used to
B. America has always been encouraging young people to go to college
C. many public institutions have replaced private ones
D. the government only finances such researches as that or placing man on the moon
