SECTION I
(1)
Adah Ofili is the protagonist of Buchi Emecheta’s novel “Second Class Citizen.” She is a Nigerian woman who faces numerous challenges and struggles as she navigates through life in both Nigeria and the United Kingdom. Adah’s character is portrayed as resilient, determined, and ambitious despite the cultural and societal limitations placed upon her.
In the novel, Adah is depicted as a strong-willed and intelligent woman who desires an education and a better life for herself. However, she faces numerous obstacles that impede her progress. Adah comes from a patriarchal society where women are expected to conform to traditional gender roles and are often denied educational opportunities. Despite this, she persists in her pursuit of knowledge and manages to attend school against her father’s wishes.
When Adah moves to the UK with her husband, Francis, her role as a second-class citizen becomes even more pronounced. She faces racial discrimination, poverty, and the challenges of raising a family while trying to secure a stable job. Adah’s experiences in the UK highlight the issues faced by immigrants, particularly those from non-Western countries, as they confront cultural shock and prejudice.
Throughout the novel, Adah’s role is that of a survivor. She endures multiple hardships, including an abusive marriage, financial struggles, and the loss of her children. Adah’s determination to improve her circumstances and provide a better life for her children drives her actions. She takes on various jobs, including working as a cleaner and selling wigs, to support her family and pursue her dreams.
Adah’s character and role in the novel symbolize the experiences of many women who find themselves trapped in oppressive cultural and societal structures. She becomes a symbol of resilience and the will to overcome adversity in the face of societal expectations, racial discrimination, and gender inequality.
(2)
The theme of cultural shock is indeed central in “Second Class Citizen.” Adah’s migration from Nigeria to England exposes her to a drastically different cultural environment, and she finds herself grappling with the clash between her Nigerian heritage and the expectations and norms of British society. This clash leads to a sense of disorientation, confusion, and cultural shock.
In Nigeria, Adah was raised within a patriarchal society that emphasized traditional gender roles and limited opportunities for women. She was conditioned to accept her secondary status and conform to societal expectations. However, in England, she is exposed to a more liberal and egalitarian society where women have greater opportunities for education and career advancement. Adah experiences a cultural shock as she navigates this new environment and tries to reconcile her ingrained cultural beliefs with the newfound possibilities available to her.
Adah’s cultural shock is not limited to gender roles and expectations but extends to language, customs, and social interactions. She struggles with the English language and accents, making communication difficult at times. Adah also encounters racism and discrimination, further complicating her cultural adaptation. She faces rejection and prejudice from both Nigerians and British individuals, highlighting the challenges faced by immigrants in a society that is often resistant to change and unfamiliar cultural practices.
Through Adah’s experiences, Buchi Emecheta portrays the complexities and difficulties faced by individuals who find themselves caught between two cultures. Adah’s journey reflects the broader immigrant experience, where individuals must navigate the unfamiliar terrain of a new culture while simultaneously grappling with the preservation of their own cultural identity. The theme of cultural shock underscores the novel’s exploration of identity, assimilation, and the quest for self-actualization in the face of cultural and societal barriers.

Unexpected Joy at Dawn” by Alex Agyei-Agyiri explores the theme of xenophobia through the interactions and experiences of the characters. The story is set in a rural Ghanaian village and revolves around the tensions and conflicts that arise between the local community and the Nigerian immigrants who have settled there.
The xenophobic attitudes in the text are primarily directed towards the Nigerian immigrants, particularly Mama Orojo and her family. The villagers view them with suspicion and prejudice due to their foreign origin. The author highlights the detrimental effects of xenophobia by showcasing the challenges faced by Mama Orojo and her attempts to integrate into the community.
One instance of xenophobia is evident when Mama Orojo’s son, Nic Jackie, is denied admission to the local school due to his Nigerian background. The villagers discriminate against him solely based on his nationality, reinforcing the idea that xenophobia can limit opportunities for individuals and perpetuate exclusion.
Another example of xenophobia is the hostility Mama Orojo experiences from her neighbors. She is subjected to derogatory remarks, isolation, and a general reluctance from the villagers to accept her as part of the community. This alienation and marginalization highlight the damaging impact of xenophobia, creating a sense of otherness and deepening the divide between the two groups.
(4)
Throughout the story, both Mama Orojo and Nic Jackie make several attempts to reconcile with the villagers and bridge the gap created by xenophobia. Despite facing adversity, they persistently seek acceptance and understanding.
Mama Orojo’s attempts at reconciliation are driven by her desire to live harmoniously with the villagers. She makes an effort to engage with her neighbors, participating in communal activities and showing kindness to those around her. She tries to break down the stereotypes associated with Nigerians by demonstrating her compassion, generosity, and willingness to contribute positively to the community.
Nic Jackie, on the other hand, strives to assimilate into the local culture and win the respect of his peers. He tries to make friends with the village children, involving himself in their games and activities. Despite initial rejection, Nic Jackie remains resilient and continues his attempts to connect with the other children. He demonstrates his eagerness to learn and adapt by embracing Ghanaian traditions, which eventually helps break down some barriers.
In response to their efforts, a few individuals in the village start to recognize Mama Orojo and Nic Jackie’s genuine intentions and gradually warm up to them. These individuals become the catalysts for change, influencing others to reevaluate their prejudiced beliefs.
As the story progresses, the tensions begin to dissipate, and a gradual reconciliation takes place. The villagers start acknowledging Mama Orojo’s contributions to the community, such as her agricultural expertise and her role in mediating conflicts. They realize that their initial assumptions about her were unfounded.
Similarly, Nic Jackie’s persistence and genuine efforts to befriend the village children pay off. Some of the children begin to accept him, recognizing that cultural differences should not hinder friendship. By embracing the local traditions and learning from each other, both the Nigerian immigrants and the villagers start to find common ground and build relationships based on understanding and acceptance.
In conclusion, “Unexpected Joy at Dawn” highlights the theme of xenophobia through the experiences of Mama Orojo and Nic Jackie. The story showcases the damaging effects of xenophobia on individuals and communities while emphasizing the importance of reconciliation and acceptance. Mama Orojo and Nic Jackie’s persistent attempts to bridge the divide ultimately lead to a gradual reconciliation between the Nigerian immigrants and the villagers, challenging the xenophobic attitudes prevalent in the community.
SECTION-II
(5)
The statement “To whom it may concern: keep this nigger boy running” reflects the dehumanization and subjugation that the narrator experiences throughout his life in the novel Invisible Man. The narrator is constantly being used and manipulated by those in power who see him only as a means to their own ends. From the very beginning of the novel the narrator is forced to fight in a brutal and degrading battle royal where he is pitted against other black boys and made to entertain a white audience. This event sets the tone for the rest of the novel as the narrator is constantly being “kept running” by others who use him for their own purposes.
The narrator is also subjected to the ideologies and expectations of both the white and black communities. He initially believes that if he adheres to the ideologies and expectations of the white society he will be able to succeed and gain recognition. However he soon realizes that no matter how hard he tries he will never be seen as an individual with his own agency. Instead he is seen as a representative of his race and is expected to conform to certain stereotypes and roles.
Furthermore the narrator’s experiences with the Brotherhood further emphasize his status as a “nigger boy” who is kept running. The Brotherhood uses him as a symbol to gain support and manipulate the masses using his invisibility to their advantage. They exploit his passion and desire for change but ultimately discard him once he no longer serves their purpose.
Overall the statement “To whom it may concern: keep this nigger boy running” highlights the dehumanization and exploitation that the narrator faces throughout the novel. He is used and manipulated by those in power stripped of his individuality and forced to conform to the expectations of society.
(6)
In Ralph Ellison’s novel “Invisible Man,” the theme of identity is central to the story. The protagonist, an unnamed African American man, embarks on a journey of self-discovery and wrestles with the complexities of his racial, social, and individual identity throughout the narrative. Ellison explores various aspects of identity, including racial identity, personal identity, and the struggle for self-definition in a racially divided society.
One of the primary concerns of the novel is the African American experience in a racially oppressive society. The protagonist grapples with the notion of invisibility, feeling marginalized and unseen by the dominant white culture. His invisibility is not merely physical but also symbolic, as it reflects the dehumanization and erasure of African Americans in society. This struggle for visibility becomes intertwined with his quest for identity.
The protagonist navigates through different spaces, encountering various social and political groups that attempt to define his identity for him. He confronts stereotypes, prejudice, and racial expectations that limit his self-expression and restrict his ability to forge his own identity. From the college he attends to the Brotherhood, a political organization, each group tries to mold him into a specific role based on their own agendas, highlighting the external pressures and expectations placed upon him.
Moreover, the protagonist’s personal journey of self-discovery is marked by a series of transformative experiences and encounters. He undergoes a process of shedding preconceived notions and societal expectations, gradually realizing the complexities of his own individuality. He moves from a state of naivety and idealism to a more nuanced understanding of his place in the world.
Ellison also explores the theme of identity through the motif of masks and disguises. The protagonist wears figurative masks to navigate through different social settings, concealing his true self in order to fit in or survive. However, these masks prevent him from fully embracing his own identity, reinforcing the idea that society forces marginalized individuals to conform and deny their authentic selves.
Ultimately, the novel suggests that true identity cannot be imposed or defined by external forces. The protagonist’s journey is a quest to define himself on his own terms, free from the constraints of societal expectations. Through his experiences, he comes to understand that true identity is a complex and multifaceted construct that cannot be reduced to simplistic categories or stereotypes.
In conclusion, the theme of identity in “Invisible Man” is a rich and intricate exploration of the African American experience in a racially divided society. Ralph Ellison delves into the struggles of the protagonist as he grapples with racial invisibility, societal pressures, and the quest for self-definition. The novel emphasizes the importance of recognizing and embracing one’s own authentic identity, beyond the limitations imposed by others, in order to achieve true selfhood.
(7)
In Emily Brontë’s novel “Wuthering Heights,” the consequences of actions play a significant role in shaping the lives of the characters and driving the narrative forward. The novel explores themes of love, revenge, and the destructive nature of unchecked passion. Through various examples, Brontë portrays how the consequences of characters’ actions can have far-reaching and devastating effects.
One example of the consequences of actions is the relationship between Catherine Earnshaw and Heathcliff. Catherine’s decision to marry Edgar Linton instead of Heathcliff leads to a series of tragic events. Heathcliff, consumed by his love for Catherine, becomes vengeful and bitter, seeking revenge on those he believes have wronged him. This ultimately leads to a cycle of violence and destruction that affects not only the main characters but also the next generation.
Another instance is Hindley Earnshaw’s mistreatment of Heathcliff. Hindley’s jealousy and resentment towards Heathcliff cause him to mistreat and degrade him, which fuels Heathcliff’s desire for revenge. As a result, Heathcliff manipulates and torments Hindley’s son, Hareton Earnshaw, perpetuating the cycle of abuse across generations. The consequences of Hindley’s actions have lasting impacts on both himself and those around him.
Additionally, the actions of Isabella Linton, Edgar’s sister, have significant consequences. Isabella, driven by infatuation and a desire to escape her unhappy marriage to Heathcliff, elopes with him. However, she soon realizes the harsh reality of his cruel and vindictive nature. Her actions lead to her own misery as she becomes trapped in an abusive relationship. She bears Heathcliff’s child, Linton, who becomes a pawn in Heathcliff’s revenge scheme, ultimately leading to Linton’s untimely death.
Overall, “Wuthering Heights” illustrates how the consequences of characters’ actions can reverberate throughout the novel, affecting not only the individuals involved but also future generations. Love, passion, and revenge drive the characters to make choices that result in devastating outcomes, showcasing the destructive power of unchecked emotions and the profound impact of actions on the lives of those involved.
(8)
The hostility between Heathcliff and Lockwood in Emily Brontë’s novel Wuthering Heights is evident from their first encounter and continues to escalate throughout the story. This conflict stems from their contrasting personalities backgrounds and experiences.
Lockwood a gentleman from London is introduced as an outsider when he rents Thrushcross Grange the neighboring estate of Wuthering Heights. Inquisitive and curious he is intrigued by the mysterious atmosphere of the moors and the unconventional nature of the inhabitants of Wuthering Heights. However his initial attempts to establish a friendly relationship with Heathcliff are met with indifference and even rudeness.
Heathcliff on the other hand is a brooding and enigmatic character. As an orphan brought to Wuthering Heights by Mr. Earnshaw he is often regarded as an outsider as well. However unlike Lockwood Heathcliff is deeply connected to the estate and its turbulent past. He resents Lockwood’s intrusion into his solitude and considers him an unwelcome guest.
Their hostility intensifies when Lockwood visits Wuthering Heights and intrudes upon a confrontation between Heathcliff and Catherine Earnshaw the love of Heathcliff’s life. Lockwood witnesses the emotional turmoil between the two and becomes increasingly involved in their complicated relationship. This intrusion exacerbates Heathcliff’s anger towards Lockwood as he feels his privacy has been violated.
Furthermore the stark differences in their social statuses and upbringings contribute to the animosity between them. Lockwood represents the upper-class gentry while Heathcliff is seen as a social outcast. These class distinctions exacerbate the tension between them and accentuate the power dynamics at play.
Ultimately Heathcliff’s deeply rooted resentment towards Lockwood stems from a combination of his own isolated upbringing his intense love for Catherine and his general disdain for anyone he perceives as an intruder or threat to his control over Wuthering Heights. This hostility between Heathcliff and Lockwood adds another layer of complexity to the narrative and serves to underline the themes of isolation obsession and revenge that permeate the novel.

NECO FINANCIAL ACCOUNTING OBJ
*FINANCIAL ACCOUNTING THEORY ANSWERS*
“`SECTION A; ANSWER TWO(2) QUESTIONS ONLY“`
(1a)
A bank reconciliation statement is a financial document that compares the balance of a company’s cash book (or general ledger) with the balance shown on its bank statement. This statement is used to identify and rectify any discrepancies or differences between the two balances. It helps ensure that the financial records maintained by the company accurately reflect its financial transactions and the actual bank account activity.
(1b)
(i) Outstanding Checks: These are checks that the company has issued but haven’t yet cleared the bank. Thus, they have been deducted from the company’s cash book but not from the bank statement.
(ii) Deposits in Transit: These are deposits made by the company that haven’t yet been credited to the bank account. They are recorded in the company’s cash book but are not yet reflected in the bank statement.
(iii) Bank Charges and Fees: The bank might deduct various charges and fees for services provided. These deductions might not be immediately reflected in the company’s cash book, causing a discrepancy.
(iv) Errors: Mistakes in recording transactions, such as incorrectly entering amounts, duplicating entries, or entering transactions in the wrong accounts, can lead to differences between the two balances.
(v) Interest and Dividends: The bank might credit the company’s account with interest earned or dividends received. If these credits are not recorded in the company’s cash book, a difference can arise.
========================
(2)
(i) Error of Principle:
An error of principle, also known as an error of fundamental character, occurs when a transaction is recorded in a way that violates the fundamental principles of accounting. This could involve misclassification of an expense as a revenue item or the use of an incorrect accounting treatment. For example, recording personal expenses as business expenses would be an error of principle.
(ii) Error of Compensation:
An error of compensation, also referred to as an offsetting error, happens when an incorrect entry is made, but the error is offset by another incorrect entry. Essentially, one mistake is canceled out by another mistake. This can result in the financial statements appearing correct even though there are errors in the underlying transactions.
(iii) Error of Omission:
An error of omission occurs when a transaction is completely left out or not recorded in the accounting books. This can happen accidentally or deliberately. Omissions can lead to inaccurate financial statements and misrepresentation of the financial position of a business.
(iv) Error of Commission:
An error of commission occurs when an entry is made in the accounting records, but it’s the wrong entry. This could involve using the wrong amount, account, or transaction details. For example, recording a payment to the wrong vendor would be an error of commission.
(v) Error of Complete Reversal of Entries:
This type of error involves transposing entire entries, essentially switching the debits and credits between two accounts. For example, if a debit entry of $500 and a credit entry of $300 were supposed to be recorded, but they are reversed so that the $500 is credited and the $300 is debited, this would be an error of complete reversal of entries. This can lead to significant distortions in financial records and financial statements.
========================
(3a)
(i) Donations and Grants: Nonprofits often rely on financial support from individuals, corporations, foundations, and government agencies. These contributions can be in the form of one-time donations, recurring donations, or grants specifically awarded for projects or initiatives that align with the organization’s mission.
(ii) Membership Fees: Many nonprofit organizations offer membership programs where individuals or entities can become members by paying a fee. In return, members might receive certain benefits such as exclusive content, event access, or the satisfaction of supporting a cause they believe in.
(iii) Fundraising Events: Nonprofits organize various fundraising events like charity galas, auctions, marathons, and community fairs. These events not only generate income through ticket sales or participation fees but also offer opportunities to engage with supporters and spread awareness about the organization’s mission.
(3b)
(i) Lack of Detail: Payment and receipt accounts provide a summarized view of financial transactions, which can lack the detailed information needed for comprehensive financial analysis.
(ii) Limited Analysis: These accounts often focus on cash flows, making it challenging to analyze non-cash items or assets that are not directly related to payments and receipts.
(iii) Timing Differences: Transactions might be recorded based on the timing of payments or receipts, leading to a mismatch between when an expense or income is recognized and when it actually occurred.
(iv) Exclusion of Accruals: Payment and receipt accounts don’t typically include accruals, which means that some expenses and incomes might not be accurately represented, potentially distorting the organization’s financial position.
(v) Lack of Future Projection: These accounts are historical in nature and don’t provide insights into future financial trends or projections, limiting their usefulness for strategic financial planning.
(3c)
(i) Taxation: One of the primary sources of revenue for the federal government is through taxation. This includes income taxes, corporate taxes, sales taxes, excise taxes, and other forms of levies imposed on individuals, businesses, and goods/services.
(ii) Borrowing: Governments often borrow money by issuing bonds and securities. Investors, including individuals, institutions, and foreign governments, purchase these bonds, providing the government with immediate funds. The government agrees to repay the borrowed amount with interest over a specified period.
========================
(4a)
(i) Source Documents:
Source documents are original records that provide evidence of a transaction or an event in accounting. These documents serve as the foundation for financial transactions and are essential for maintaining accurate and reliable financial records. Examples of source documents include invoices, receipts, purchase orders, bank statements, contracts, and payroll records. They offer a trail of evidence that supports the entries made in the accounting system, ensuring transparency and traceability of financial transactions.
(ii) Debit Note:
A debit note is a document used in accounting to inform a customer that they owe additional payment to a business. It is issued by a seller to their customer when there is an increase in the amount owed, usually due to goods being returned, pricing discrepancies, or other adjustments. The debit note serves as a formal request for the customer to pay the outstanding amount, and it often includes details about the reason for the increased charge.
(iii) Prime Entry:
Prime entry, also known as “original entry,” refers to the practice of recording financial transactions directly into the accounting system as they occur. This involves entering transaction details into the appropriate accounts in the general ledger or subsidiary ledgers without the need for intermediate steps like journal entries. Prime entry reduces the risk of errors and enhances the accuracy of financial data.
(4b)
(i) Purpose: The purpose of government accounting is to track and report on the financial activities and performance of government organizations including the allocation and utilization of public funds While Private sector accounting on the other hand focuses on providing financial information to stakeholders like investors shareholders and creditors with the aim of facilitating business decision-making profit maximization and assessing the organization’s financial health.
(ii) Accountability: Government accounting is primarily focused on ensuring transparency and accountability in the use of public funds with a greater emphasis on compliance with legal and regulatory requirements. In contrast private sector accounting is more oriented towards providing reliable and relevant financial information for internal and external stakeholders with a focus on generating profits and increasing the value of the organization.
(4c)
(i) Budgeting and Financial Analysis
(ii) Auditing and Assurance

(i) Classifying the alkanols:
– Butan-2-ol: secondary alkanol
– 2-methylpropanol: secondary alkanol
– 2-methylpropan-2-ol: tertiary alkanol
(ii) Two methods to prepare ethanol commercially:
– Fermentation: Ethanol can be produced by the fermentation of sugars using yeast. This is commonly used to produce alcoholic beverages and biofuels.
– Hydration of ethene: Ethanol can be produced by the hydration of ethene (ethylene) in the presence of a catalyst, such as phosphoric acid.
(iii) To calculate the relative molecular mass of Z, we need to compare the rates of effusion or diffusion of Z and hydrogen. The rate of effusion/diffusion is inversely proportional to the square root of the molar mass. Since hydrogen diffuses 6 times as fast, the molar mass of Z is 6 times larger than the molar mass of hydrogen. Therefore, the relative molecular mass of Z is 6 * 2 = 12.
(bi) The electronic configuration of oxygen using s, p, d, f notation is 1s2 2s2 2p4.
(ii) Three physical properties of oxygen:
(i) Oxygen is a colorless and odorless gas.
(ii) It is slightly soluble in water.
(iii) Oxygen supports combustion and is necessary for respiration.
(iii) Two rules for naming alkenes:
1. Alkenes must have the ending “-ene” in their name.
2. The longest continuous carbon chain containing the double bond is used as the base name, and the position of the double bond is indicated by the lowest possible number.
(iv) Equation for the oxidation reaction of ethene:
Ethene + Oxygen → Carbon Dioxide + Water
C2H4 + O2 → CO2 + H2O
(ci) Endothermic reaction: A reaction that absorbs heat (energy) from the surroundings, resulting in a decrease in temperature.
(ii) Equation for the laboratory preparation of hydrogen using dilute tetraoxosulphate(VI) acid and Zinc:
Zn + H2SO4 → ZnSO4 + H2
(iii) The type of reaction involved in (cii) is a displacement reaction, where zinc displaces hydrogen from the acid to form hydrogen gas.
(iv) Three uses of hydrogen:
(i) Hydrogen is used as a fuel for combustion engines and fuel cells.
(ii) It is used in the production of ammonia for fertilizer and other chemicals.
(iii) Hydrogen is used in the hydrogenation of oils and fats in the food industry.
_ALL ANSWERS TO NUMBER 5
(ai)
a base is a substance that can accept protons or donate pairs of electrons. Bases typically have a pH greater than 7 and can neutralize acids.
(ii) Examples of basic oxides include calcium oxide (CaO) and sodium oxide (Na2O).
(iii) Two uses of iodine are:
(i)Iodine is used as an antiseptic to disinfect wounds and prevent infections.
(ii) Iodine is also used in the production of X-ray contrast agents, which helps in visualizing organs and tissues during medical imaging.
(iv) One difference between an aliphatic and aromatic hydrocarbon is the structure. Aliphatic hydrocarbons are linear or branched chains of carbon and hydrogen atoms, while aromatic hydrocarbons contain a ring structure with alternating double bonds.
(v)To calculate the vapour density of XCl3, we need to know the molar mass of X. Without additional information on the element X, we cannot calculate the vapour density.
(bi)Three factors that affect the rate of a chemical reaction are:
(i)Concentration: Increasing the concentration of reactants generally increases the rate of reaction.
(ii)Temperature: Higher temperatures usually increase the rate of reaction as particles have more energy and move faster.
(iii) Catalysts: Catalysts are substances that can speed up a reaction by providing an alternative reaction pathway with a lower activation energy.
(ii)The law of conservation of energy states that energy cannot be created or destroyed in an isolated system; it can only be transferred or transformed from one form to another.
(iii) Two examples of chemical change are:
(i)Combustion, where a substance reacts with oxygen and releases heat and light.
(ii)Rusting of iron, where iron reacts with oxygen in the presence of water and forms iron oxide.

*GIVEN:*
D=1960cm
R=D/2=1960/2cm
=>The area of the farmland is A = πr²/4 = π(1960cm/2)²/4 = 3,018,306.92 cm²
(5aii) The number of mounds on the farmland is N = A/2m² = 1,509,153.46 mounds
(5aiii) The total number of setts needed is S = N * 5000 sett/ha = (N * 5000 sett/ha) * (10,000 m²/ha) = 75,457,673,000 setts

(i) Weeds help in checking soil erosion.
(ii) Some weeds ate useful as food for humans.
(iii) Some weeds serve as feed for livestock.
(iv) Certain weeds have medicinal properties.
(6d) Farmland calculations:
(i) Area of the farmland:
Length = 60m
Width = 30m
Area = Length × Width
Area = 60m × 30m
Area = 1800m²
(ii) Plant population in the farmland:
Spacing = 30cm by 30cm
To calculate the number of plants, we need to convert the spacing to meters:
30cm = 30/100 = 0.3m
Plant population = (Length in meters / Spacing in meters) × (Width in meters / Spacing in meters)
Plant population = (60m / 0.3m) × (30m / 0.3m)
Plant population = 200 × 100
Plant population = 20,000 plants
Therefore, the plant population in the farmland is 20,000.
