- Read the following narrative and answer the questions that follow.(Solved)
Read the following narrative and answer the questions that follow.
Once upon a time, Warthog and Hare were best friends and they lived together. They shared duties according to each one’s abilities. Hare had speed, therefore, duties involving fetching or delivering items fast were left to him, while Warthog, who was gifted in cooking, handled kitchen duties. However, Warthog had his shortcomings. He lost his temper easily and was ready to fight at the slightest provocation. Hare tolerated him all the same.
Things were not always good in the kitchen. The two always quarrelled over missing food. Warthog was always on the defence, denying any wrong doing. One day, Hare bought five tilapia fish but warthog only served two. When he was asked what happened to the other three fish, as usual, Warthog insisted that he knew nothing about the missing fish. Hare was aware that arguing or fighting would not bring back the lost fish. He also knew that he was smaller and could never win a physical fight against warthog.
Not long after the missing fish incident, Hare and Warthog went hunting. They chanced upon a young gazelle too weak to run. They took the gazelle home and slaughtered it. Warthog as usual was the chef. Hare left him and went for a stroll as he waited for the meat to cook. When he returned, warthog, was sleeping under a shady tree, pretending to be very tired, after cooking. Hare opened the lid and Lo! There were only few pieces of meat left.
Hare was really angry and he threatened to beat Warthog up if he failed to account for the missing pieces. Under faked annoyance, Warthog pounced on hare mid-sentence and beat him up thoroughly. Hare promised to get even. That evening, hare went to see Mr. Squirrel who was the best known magician in the whole region. Squirrel gave him a pot of honey to take to Warthog. When he went back home, Hare feigned forgiveness and invited warthog to taste the honey.
Warthog approached him cautiously, he knew that Hare was quite tricky at times. He thought the pot might contain a snake.
So he started apologizing to Hare from a distance for beating him but Hare laughed it off, reminding him that the differences between them were history and they should both start anew. Warthog, who loved honey, approached hare and scooped some which he ate greedily. However, what he did not know was that it had passed through the hands of Squirrel who had laced it with poisonous herbs that would affect Warthog and his descendants.
After eating half the pot’s contents, Warthog felt dizzy and sleepy. When he woke up, he could not remember anything, his brain had been affected by the poisonous herbs. He forgot about his friendship and quarrel with Hare. He did not even remember eating the honey. He was so confused that he ran off into the bush. Warthog’s brain has never recovered. Till now he is always confused and forgetful.

b) Identify and illustrate three features of style in the narrative.
c) What makes Warthog and Hare best friends?
d) What are the economic activities in the community where the story is taken from?
e) How has Hare been portrayed in the story?
