Hence,RI is the reason and RII is irrelevant. Choice (1)58. RI is certainly the fact which violates human rights and even corrupts the youth.So, it could be the reason. Human rightsgroup and the rise in charges of the MMSare in no way related. So, RII cannot bethe reason. Choice (1)59. RI is not the reason.
