Directions : Read the passage given below carefully and answer the question by selecting the correct/most appropriate options. There is something we all want to do, although few of us readily admit it : Get rid of guests. For nine months in the year, only my closest friends come to see me. Then, when temperatures start soaring in the plains, long-lost acquaintances suddenly remember that I exist, and people whom I am barely able to recognize appear at the front door, willing to have me put them up for periods ranging from six days to six weeks. Occasionally, I am the master of the situation I inform them that the cottage is already bursting, that people are sleeping on the floor. If the hopefuls start looking around for signs of these uncomfortable guests, I remark that they have all gone out for a picnic. The other day I received visitors who proved to be more thick-skinned than most. The man was a friend of a friend of an acquaintance of mine. I had never seen him before. But on the strength of this distant relationship, he had brought his family along. I tried the usual ploy but it didn't work. The man and his family were perfectly willing to share the floor with any others who might be staying with me. So I made my next move. 'I must warn you about the scorpions', I said. The scorpion-scare is effective with most people. But I was dealing with professionals. The man set his son rolling up the carpet. 'Sometimes centipedes fall from the ceiling', I said desperately. We were now interrupted by someone knocking on the front door. It was the postman with a rejected manuscript, his arrival inspired me to greater inventiveness. 'I'm terribly sorry', I said, staring hard at a rejection slip. 'I'm afraid I have to leave immediately. A paper wants me to interview the Maharishi. I hope you won't mind. Would you like the name of a good hotel ?' 'Oh, don't worry about us', said the woman expansively. 'We'll look after the house while you are away.'
