1. Read the passage and answer the questions that follow:-

Fiction originally meant anything made up or shaped. As we understand the world now, it refers to prose stories, short or long-a meaning it has retained its first recorded use in this sense.Fiction is distinguished from the works it imitates such as historical accounts, reports,biographies, autobiographies , letters, personal memoirs and meditations. While fiction often resembles these forms, it has a separate identity because it originates not in historical facts but in the imaginative and creative of powers the author. Writers of fiction may include historically accurate details, but their primary goal is to tell a story and say something significant about life.

The essence of fiction, as opposed to drama, is narration, the recounting or telling of a sequence of events or actions. The earliest works of fiction relied almost exclusively on narration , with speeches or dialogue being reported rather or quoted directly.Much recent fiction includes extended passages of dialogue, thereby becoming more dramatic even though narration is still the primary mode.

Fiction is rooted in ancient legends and myths. Local priests narrated stories about their gods and heroes, as shown in some of the narratives of ancient Egypt. In the course of history, travelling story tellers would appear in a court or village to entertain listeners with tales of adventure in faraway countries.Although many of these were fictionalized accounts of events and people who may not even have existed, they were largely accepted as fact or history. An especially long tale, an epic, was recited over a period of days. To aid their memories and to impress and entertain their listeners, the storytellers chanted their tales in poetry often accompanying themselves on a stringled instrument.

Indeed, fiction is strong because it is so real and personal. Most characters have both first and last names; the countries and cities in which they live are modeled on real places; and their actions and interactions are like those which readers themselves have experienced, could experience, or could easily imagine themselves experiencing.

Along with attention to character, fiction is concerned with the place of individuals in their environments. In the simplest sense, environment is a backdrop or setting within which characters speak, move and act. But more broadly, environment comprises the social, economic, and political conditions that affect the outcomes of people’s lives. Fiction is usually about the interaction among people. Indeed, in typical work of fiction there are always many forces, both small and large , that influence the ways in which characters meet and deal with their problems.

The first true works of fiction in Europe, however were less concerned with society or politics than adventure. These were the lengthy Spanish and French romances of the sixteeth and seventeethcenturies . In English the word novel was borrowed from French and Italian to describe these works and to distinguish them from medieval and classical romances as something that was new.

Once great numbers of people could read for themselves, the paying audience for literature expanded. A writer could write a novel and receive money for it from a publisher, who could then profit from a wide sale.

1

Reading a novel could even be a social event , for people would reach to each other as a means of sharing the experience. With this wider audience , authors could make a career out of writing. Fiction had arrived as a major genre of literature.

3. Read the oral narrative below and answer the questions that follow;-Along time ago there was old man whose name was Ramogi. This old man had two sons.

These two sons called Labon’go and Gipir had wives. Labon’go was the elder of these two. When Ramogi died, Labon’go became the chief of the homestead. He was to look after his father’s property, including the family’s sacred spear.

There was a lot of forest land and elephants were in plenty. The elephants used to come and destroy crops. One day, when Labon’go was out hunting, an elephant came near the homestead and destroyed some of the crops. Gipir, who was still at home, was so furious that he quickly, without thinking, picked up the family spear and threw it at the elephant. The spear stuck into the elephant’s side and the elephantescape. The elephant ran with the spear until it reached the forest. When Labon’go came back from hunting ,his wife told him about the loss of his spear. She explained to him how an elephant had damaged the crops and how Gipir had bravely driven it away losing the sacred spear in the process. On hearing this Labong’o angrily went straight to his brother’s house and and demanded the spear , saying, Gipir, see that you return the family sacred spear and make sure it is that particular one that you threw at the elephant”Gipir tried to appease his brother by making beautiful spear but Labon’go refused to accept them.

One day Gipir told his wife, “ Please prepare for me a lot of food. I have a long journey to make.” The wife prepared for him a lot of food and Labon’go set out. After a long, dangerous journey, in which his life was threatened by wild animals and huge poisonous snakes, he reached a forest called gondliech, the home of elephants. In the forest he met an old woman. This old woman asked him, “What have you come to do here in the forest?”.Gipir told her what had happened. He told her how he had pierced an elephant with the sacred family spear, and that the elephant had run with it into the forest.

The woman became angry and said “so it is you who is killing my elephants?” Gipir replied politely and said that all the he wanted was the sacred spear of the family , if she could kindly help him to find it. The old woman then showed him where she kept spears. He searched among them and found the spear that Labon’go wanted. The old woman then gaveGipirsome beads to take to his wife.

When Gipir reached home he immediately took the spear to Labon’go. Labon’go was very happy and he thanked him.

Next morning Gipir spread out the beads he had been given by the old woman, in preparation for his wife to string them. Everyone in the homestead came out to see the beautiful beads .Labon’go’s child was playing where the beads were being strung. Without being noticed, he took one and swallowed it. Gipir knew that his time for revenge had come. until the child excreted. The excrement was searched thoroughly, but no bead was found . This action was repeated several days of trying and failing. Labon’go asked Gipir to cut the child open and take his bead. Gipir realized that this was a trap and he refused. He knew that if he killed the child and took out the bead Labon’go would certainly say that he wanted Gipir’s child.

3

Meanwhile Labon’go grew tied of the continual reminder from Gipir that he wanted his bead back, just as the demand for the sacred spear had tired Gipir.

When Labon’go killed and cut up the child, the bead was found hidden in the linings of the stomach. The child was buried. When this happened Gipir was forced to shift from his homestead to another land.

Labon’go also moved and they never saw one another again.“I hope I grew and attain the height of the tree at my uncle’s place.
