Statement 3 opens the idea by saying that we need to learn how to deal with legitimate criticism. By fixing the position of 1, we can arrange the sentences in the right order. 1 says 'we will all live under mob rule until then...' To what does this then refer? It must refer to some specific time or event. It refers to the time till we have new norm (read statement 4). A new norm will arise... we will have to live under a mob rule until then... Thus 4 and 1 form a pair. 2 cannot come after 1, nor does it open the para. The best place for 2 is after 3 . Thus the right sequence is 3241 .
