Read the passage given below and answer the questions that follow: (1) A sense of humour is what separates man from other living beings. Man knows how to laugh at others and even at himself. We, human beings cannot do without humour. We cannot enjoy our conversations, our dialogues if we cannot add humour to them to make others smile or laugh. We don't know how to spend our time when we are alone or sad. We need company of others and humour lightens our day and we share common interests with others. When we know what to say and when to say it helps us to build healthy relationships. Sometimes humour tends to lead us into difficult situations when we exaggerate our point and thus tease others.
