28.	The peddler comes out as a person with subtle sense of humour. How does this serve in lightening the seriousness of the theme of the story and also endear him to the reader?
Answer» The peddler is one of the most interesting characters in this story. His theory of rattrap is an excellent example of humour in the story. The very idea of comparing a man’s greed for money and wealth to a rat which hungrily looks around for food and finally gets in the trap, evokes humour. Moreover, the tramp himself committed the same error by stealing the crofter’s money is so ironical. The peddler’s attempt not to undeceive the ironmaster, despite being afraid to accept the invitation, is very comical. Some of the other funny scenes are when he displayed his smartness after he was recognised by the ironmaster. The display of his anger and frustration at the point when the ironmaster threatened to call the police is also very humorous. In spite of all the things that he did, he came out to be a very lovable character and endears us when he confessed his guilt and left the house in an honourable manner leaving the stolen money, a note and a Christmas gift for Edla.

29.	The Rattrap’ focuses on human loneliness and the need to bond with others. Comment.
Answer» No doubt the story focuses on human loneliness and the need to bond with others. The protagonist of the story, i.e. the peddler, was a vagabond who had no family and led a lonely life. As he had no companion to talk to, he was left to his own meditations. The crofter was also a lonely man with no wife or children. When he saw the peddler, he was happy to get someone to talk to. That is why he treated him with good food and tobacco. Moreover, the ironmaster and his daughter Edla too were leading a lonely life. The ironmaster’s wife died long ago, and his sons lived abroad. They had no family and friends to celebrate Christmas. Thus, the story deals with the loneliness of human beings in different situations and their struggle to cope with loneliness.

32.	The reader’s sympathy is with the peddler right from the beginning of the story. Is the sympathy justified?
Answer» ‘The Rattrap’ is written in the backdrop of industrial revolution in Sweden in the second half of the nineteenth century. Many families were displaced by the growing industry and some people were reduced to a life of extreme poverty. The peddler in the story was a victim of such an economic change. He managed his life by begging and stealing. The pitiable state in which he was living evokes the sympathy of the reader. Even when he stole the money of the crofter, we don’t consider him to be a criminal. It was taken as a normal reaction of a poor man when he saw so much money easily available to him. Thus, the peddler’s extreme poverty and the circumstances in which he lived, justifiably make the reader sympathetic to him from the beginning of the story.

35.	Choose the incorrect statement among the following :1. The Hausa are a primarily pastoral tribe of Nigeria for whom cattle is a symbol of wealth.2. The Bindibu of Australia are primitive hunters and prefer to stay near the source of water.1. Only 12. Only 23. Both 1 and 24. Neither 1 nor 2
Answer» Correct Answer - Option 1 : Only 1 The correct answer is Only 1. Hausa People They are the largest ethnic group in Africa and the second largest language after Arabic in the Afroasiatic family of languages. These tribes is spread in many African continent countries. The Hausas specialized in blacksmithing, fishing, hunting, agriculture, and salt-mining. They are not a pastoral tribe. Hence statement 1 is not correct. The Fulani are the primary pastoral group in Nigeria with a population of approximately 15.3 million. Bindibu People They are natives of western Australia. They are lean and dark but healthy. They are skilled trackers and some of them use wooden throwing sticks or boomerangs and spears. They also domesticate the dingo, a wild dog that assists them in tracking down kangaroos, rabbits and birds. The women gather grass, roots, seeds, berries, moles and insects, to supplement their diet. Like the wandering Bushmen, the Bindibu move in family groups in search of fresh hunting grounds. Hence statement 2 is correct.
