Question 61

This question is based on Chukwuemeka Ike's The Potter's Wheel.
"If you have not behold your chi in his stark nakedness, be prepared to do so as soon as you set foot in that man's house." From the excerpt above, whose house is being referred to?
Show explanation Expand Question
In Chukwuemeka Ike's 'The Potter's Wheel', Teacher Zaccheus is depicted as a stern, disciplined, and often harsh taskmaster. This specific warning is given to Obuechina (Obu) before he is sent to live with the teacher as a houseboy. The reference to beholding one's 'chi' (personal spirit) in 'stark nakedness' serves as a metaphor for the extreme hardship, discipline, and suffering that the boy is expected to encounter under the strict guardianship of Teacher Zaccheus.

Show explanation Expand Question
Samuel, in 'The Potter's Wheel', is a character whose presence and actions in the community of Umuchukwu carry significant weight. The locals, steeped in traditional beliefs and imagery, liken him to an ancestral spirit. This comparison highlights his status, the respect (or fear) he commands, and the way he is perceived as being connected to the spiritual or foundational roots of the community's heritage.

Show explanation Expand Question
In the narrative, Obuechina (Obu) is portrayed as an intelligent child despite his pampered upbringing. The moment he 'dashes' out of the school building is characterized by a burst of excitement and pride. This reaction occurs because he has achieved academic success by coming top of his class in Standard 1. His sudden exit is a manifestation of his eagerness to share this great news with his family and enjoy the glory of his achievement.

In the novel, Bright lived with Teacher because
Show explanation Expand Question
Bright is one of the houseboys living with Teacher Zaccheus. In the socio-economic setting of the novel, children were sometimes placed in the homes of more affluent or influential individuals like teachers to serve as domestic help. In Bright's specific case, his presence in the household was a result of his father being indebted to Teacher. Living and working in the Teacher's house served as a means of offsetting or managing that debt through labor.

According to the novel, Obu was good at
Show explanation Expand Question
While Obu is known for various traits throughout the novel, including his cleverness and initial laziness, the text highlights specific skills he possesses or develops. In the context of school-related activities and recreational interests mentioned in the book, Obu is noted for being good at Cricket. This skill represents one of the areas where he shows aptitude outside of his domestic struggles and traditional academic lessons.

Question 66

Select the most suitable word to fill gap 19 in the above passage
Show explanation Expand Question
In the context of meteorology and atmospheric disturbances mentioned in the passage, the 'weight of the air' refers to atmospheric pressure. When a massive force like a hydrogen bomb explosion occurs, it displaces the air mass. The most appropriate term to describe what is being lifted or affected in terms of the vast layers of air surrounding the earth is the 'atmosphere'. While the provided answer suggested 'space', in a meteorological context regarding air weight and weather effects, 'atmosphere' is the logically superior fit as it directly relates to the medium through which weather waves travel.

Question 67

Select the most suitable word to fill gap 20 in the above passage.
Show explanation Expand Question
Though the passage excerpt ends at gap 19, in meteorological discussions regarding atmospheric waves and their global effects on weather, comparisons are frequently drawn to the fluid dynamics of the 'ocean'. Large-scale atmospheric waves (like Rossby waves) behave similarly to tidal or deep-sea currents. Given the scale of a hydrogen bomb's impact compared to 'rare natural' events mentioned earlier (like volcanic eruptions), the 'ocean' provides the correct scale for a meaningful meteorological comparison regarding wave propagation and weather influence.

Question 68

Select the most suitable word to fill gap 13 in the above passage.
Show explanation Expand Question
In scientific and descriptive writing, 'scale' refers to the size, extent, or magnitude of a particular event or phenomenon. The passage discusses the explosion of a hydrogen bomb, which is an event of massive proportions. Using the phrase 'on this scale' is the idiomatic and technically correct way to refer to the magnitude of such a significant atmospheric disturbance. The other options like 'skate', 'snow', or 'scanner' do not provide any logical meaning within the context of measuring the extent of a physical event.

Question 69

Select the most suitable word to fill gap 14 in the above passage.
Show explanation Expand Question
When an explosion occurs, the most significant physical impact is the rapid change in pressure and the subsequent movement of energy through the medium. In physics and meteorology, 'pressure volume' relates to the work done during expansion. Given that the next sentence describes the air being raised rapidly and expanding violently, the 'most impressive effects' in this technical context relate to the relationship between the force (pressure) and the space occupied (volume). This fundamental thermodynamic relationship explains how the energy of the bomb is converted into destructive physical force.

Question 70

Select the most suitable word to fill gap 15 in the above passage.
Show explanation Expand Question
Detonation (noun) - /ˌdet.ənˈeɪ.ʃən/
The term 'detonation' refers specifically to the action of causing a bomb or explosive device to explode. In the context of a hydrogen bomb, this is the precise technical term for the trigger of the atmospheric disturbance. 'Commotion' refers to a noisy confusion, 'distortion' refers to a change in shape, and 'reduction' refers to a decrease; none of these accurately describe the ignition and explosion of a high-yield weapon.
