Walter: For the economically privileged in a society to tolerate an injustice perpetrated against one of society' s disadvantaged is not just morally wrong but also shortsighted: a system that inflicts an injustice on a disadvantaged person today can equally well inflict that same injustice on a well-to-do person tomorrow. Larissa: In our society, the wealthy as well as the well-educated can protect themselves against all sorts of injustices suffered by the less well-off. Allowing such injustices to persist is bad policy not because it places everyone at equal risk of injustice but because it is a potent source of social unrest. Larissa responds to Walter by doing which one of the following?
A: charging Walter with stopping short of recognizing the full implications of his position
B: questioning Walter's authority to address matters of social policy
C: drawing implausible consequences from Walter's assumptions
D: providing an alternative reason for accepting the truth of Walter's conclusion
