Since man has done so much【C10】________, it is【C11】________to man to try to put matters right—if it is not already too【C12】________.If there is to be any remedy for our ills, that remedy ultimately lies in the hands of the【C13】________, and the sooner they start doing something about it, the【C14】________.
