Correct Answer: C) perennating organs

Explanation

Grasses are plants that grow in savannas, and they are known to recover quickly from bush fires. This is because they have perennating organs. Perennating organs are structures in plants that enable them to survive adverse conditions such as fires, drought, and cold temperatures. In this case, the perennating organs in grasses are the parts of the plant that remain alive after the fire, such as the roots and rhizomes. Option A suggests that grasses recover quickly because of their fibrous roots. While it is true that grasses have fibrous roots, they are not the main reason why grasses recover quickly after bush fires. Option B suggests that grasses recover quickly because of their succulent stems. However, this option is incorrect because grasses do not have succulent stems. Option D suggests that grasses recover quickly because of their rapid growth rate. While it is true that grasses grow quickly, this is not the reason why they recover quickly after bush fires. Therefore, the correct answer is option C, perennating organs. Grasses have perennating organs that enable them to regrow quickly after bush fires. It is important to note that not all plants have perennating organs, and different types of perennating organs exist in different plants. Overall, grasses have perennating organs that allow them to quickly recover from bush fires in savannas.

Correct Answer: D. inter-personal relations

Explanation

Emecheta uses the third person (omniscient) narrative technique. The story is told by a narrator who is not within the story, but the novelist is able to bridge the gap between the narrator and the reader which sometimes occurs ir these circumstances.

She does this by allowing the story to flow almost from the consciousness of her characters. The reader is thus able to empathize with the main character Nnu Ego, understand the motives for her actions and see the story from he perspective. Her aims and aspirations, her frustrations at her inability to bear a child, and her disappointment at thE treatment she receives from her male children are vividly captured through this narrative style. Nnu Ego's story does not begin in Lagos; nor is it a story that begins in child-bearing for Nnu Ego. Her initial painful experiences in life are not to do with her losing a child; rather she has been a childless woman.

Buchi Emecheta adopt: the style 'in media res', that is, she starts the story from a point later in time according to the chronology of events. This technique of narration has the effect of surprising the reader when the earlier events begin to unfold. It also gives thE narrator room to shuttle between later and earlier events and roam in time. In starting the narrative from a certain point inside the order of the story, the narrator does not cut the story short The earlier events will be recalled and integrated in the course by means of flashback. In The Joys of Motherhood Emecheta uses flashback very successfully.

The novelist tells the earlier experiences of Nnu Ego in Ibuza in late chapters after opening the novel in Lagos. Indeed, Nnu Ego is not even born until towards the end of the second chapter which largely narrates her parentage. The real events that culminate in the Lagos episode are found in Chapter Four Mama Abby's story is not told and if we were to insist on being told how her daughter came to disgrace the family, oil medium would be a flashback.

Explanation

(a) Passed : Failed = 4 : 1

\(p(Passed) = \frac{4}{5} ; p(Failed) = \frac{1}{5}\)

(i) p(at least 3 passed) = 1 - [p(0) + p(1) + p(2)]

p(0 passed) = \(^{7}C_{0} (0.8)^{0} (0.2)^{7} = 0.0000128\)

p(1 passed) = \(^{7}C_{1} (0.8)^{1} (0.2)^{6} = 0.000358\)

p(2 passed) = \(^{7}C_{2} (0.8)^{2} (0.2)^{5} = 0.0043\)

p(at least 3 passed) = \(1 - [0.0000128 + 0.000358 + 0.0043] = 0.9953\)

(ii) p(between 3 and 6 students failed) = p(4 or 5 students failed)

= \((^{7}C_{4} (0.8)^{3} (0.2)^{4}) + (^{7}C_{5} (0.8)^{2} (0.2)^{5})\)

= \(0.02867 + 0.0043008\)

= \(0.03297\)

(b) p(a six) = p = \(\frac{1}{6}\), p(not a six) = q = \(\frac{5}{6}\)

Die thrown five times;

Binomial distribution function is \((p + q)^{5} = p^{5} + 5p^{4}q + 10p^{3} q^{2} + 10p^{2} q^{3} + 5pq^{4} + q^{5}\)

p(a six three times) = \(10p^{3} q^{2}\)

= \(10(\frac{1}{6})^{3} (\frac{5}{6})^{2}\)

= \(\frac{250}{7776}\)

= 0.03215
