Question ID:PT33 S1 Q19 Passage:Historian:  The spread of literacy informs more people of injustices and, in the right circumstances, leads to increased capacity to distinguish true reformers from mere opportunists. However, widespread literacy invariably emerges before any comprehensive system of general education; thus, in the interim, the populace is vulnerable to clever demagogues calling for change. Consequently, some relatively benign regimes may ironically be toppled by their own "enlightened" move to increase literacy.  Stem:Which one of the following is an assumption on which the historian's argument depends? Correct Answer Choice:DChoice A:A demagogue can never enlist the public support necessary to topple an existing regime unless a comprehensive system of general education is in place. Choice B:Without literacy there can be no general awareness of the injustice in a society. Choice C:Any comprehensive system of general education will tend to preserve the authority of benign regimes. Choice D:A lack of general education affects the ability to differentiate between legitimate and illegitimate calls for reform. Choice E:Any benign regime that fails to provide comprehensive general education will be toppled by a clever demagogue.
