Part R begins with "and consciously develop a new", which naturally flows from "urgently". So, R comes first.Part R ends with the adjective "new", which needs a noun to modify. Part P begins with the noun "ethics". Hence, P follows R.Part P ends with "respects, and responds", and part Q continues with the adverb "humanely to, the strangers in our cities", completing the verbal phrase "responds humanely to". Thus, Q follows P.The correct arrangement is RPQ.
