Question 3662Question →

In a classic federal system of government, component state governments possess coordinate authority with the central government rather than operating as legally subordinate agencies of the central government.

Show answer & explanation

Answer: True

Answer

True
The statement is correct because a fundamental defining feature of federalism is that component states and the central government exist as coordinate authorities, each sovereign within its constitutional domain.

Step-by-Step Solution

1
Examine the constitutional relationship between the central authority and regional units in a federal political structure.
Federalism establishes a division of legislative, executive, and judicial powers entrenched in a written constitution.
The source and legal status of regional authority dictate whether a system is federal or unitary.
2
Evaluate whether state units are subordinate to or coordinate with the federal government.
Neither tier of government can unilaterally strip the other of its constitutionally allocated powers, ensuring coordinate autonomy.
Coordinate status prevents the central government from treating component state governments as simple administrative extensions.

The newly appointed Inspector of Weights and Measures arrived in the district with a grand leather briefcase, declaring that every market scale would henceforth be calibrated to the millimeter. Yet, as the weeks turned into months, his days were consumed entirely by filling requisition forms for official rubber stamps to validate his inspection ledger. Meanwhile, the village butchers continued to measure beef by the palm of their hands, completely oblivious to the inspector's mountain of pending paperwork.
Nneka smoothed the stiff, imported silk of her evening gown, sitting amidst the soft clinking of wine glasses and polite laughter of the diplomatic reception. Across the room, someone mentioned the rains returning to the eastern hills, and suddenly the smell of damp red earth flooded her consciousness, making the crystal chandeliers above seem fragile and hollow. She smiled at a passing ambassador, but her heart remained anchored to a thatched kitchen half a world away.
For forty years, Pa Ezekiel had tended the quiet cocoa grove, listening to the rhythmic hum of weaverbirds at dusk. Today, the deafening roar of yellow bulldozers tore through the valley, uprooting ancient trees to lay the foundation for a steel processing plant. He held the fistful of bank notes given as compensation, feeling not the warmth of wealth, but the cold weight of a legacy traded for transient progress.
Chief Akpan boasted that no storm in the Bight of Biafra could tilt his newly constructed oil vessel, the Neptune's Crown. Ignoring the seasoned warnings of old fishermen regarding the sudden July swells, he ordered the full cargo loaded past the safety waterline. By midnight, when the gale struck, it took neither a monster wave nor a collision to sink the vessel—only the quiet, relentless seeping of water into an overladen hull.

A traditional artisan who previously forged agricultural tools exclusively for his immediate family's farming needs decides to employ specialized assistants to manufacture standardized hoe blades in bulk for sale to regional agricultural cooperatives. Which fundamental shift in the nature of production is demonstrated by this artisan's transition?

Show answer & explanation

Answer: A transition from direct production to indirect production, reliant on specialization and market exchange

Answer

The artisan underwent a transition from direct production to indirect production, reliant on specialization and market exchange.
The correct option accurately identifies the shift from direct production (producing goods solely for personal or household consumption) to indirect production (producing goods intended for exchange in the market through trade and specialization). The introduction of specialized assistants and bulk production for cooperatives highlights key elements of indirect production.

Step-by-Step Solution

1
Analyze the initial production state
The artisan forged tools exclusively for personal/family use without market exchange, which defines direct production.
Direct production satisfies immediate personal consumption needs directly from one's own efforts.
2
Analyze the restructured production state
The artisan engaged specialized workers to produce goods in bulk intended for sale to external buyers (cooperatives).
Producing goods meant for exchange and satisfying the needs of others through trade characterizes indirect production.
3
Synthesize the production transformation
The transition moves from self-sufficient direct production to market-oriented indirect production utilizing division of labor.
Indirect production relies heavily on specialization, trade, and commercial distribution channels.

A village council mandates the ritual execution of a captive boy to uphold ancestral tradition, causing irreversible emotional erosion and factional splintering among the elders.

Matches

Show answer & explanation

Answer

1. Educated protagonist's isolation matches Post-colonial hybridity, disillusionment, and double alienation.
2. Matriarch's secret collective matches Subversive female agency operating covertly within patriarchal social structures.
3. Colonial officer's report matches Cultural imperialism and the Eurocentric distortion of African history.
4. Ritual execution of captive boy matches The tragic consequences of unyielding adherence to rigid communal dogma.
Each narrative plot scenario maps precisely to its overarching thematic concern: the displaced protagonist highlights post-colonial double alienation; the matriarch's silent network represents subversive female agency under patriarchy; the colonial report exemplifies Eurocentric distortion of indigenous history; and the ritual sacrifice illustrates the destructive impact of unyielding communal dogma.

Step-by-Step Solution

1
Analyze the first scenario regarding the educated protagonist's struggle between rural tradition and urban civil service.
Identify that the conflict centers on cultural displacement and being caught between two worlds without belonging to either.
This dual estrangement directly defines post-colonial double alienation.
2

Connect outward submission paired with hidden economic independence to covert gender resistance.
It illustrates how women maneuver around male-dominated social restrictions.
3
Evaluate the third scenario where a colonial official documents indigenous rebellion as irrational violence.
Determine that the narrative motif focuses on biased historical record-keeping by colonizers.
This motif is the hallmark of Eurocentric historical distortion and cultural imperialism.
4
Assess the fourth scenario detailing the ritual killing mandated by tradition and the resulting elder guilt.
Recognize that rigid adherence to ancient custom causes psychological remorse and internal decline.
This demonstrates the destructive effect of unyielding dogma on society.

Historical analysis of financial record-keeping demonstrates a major shift during the Industrial Revolution, expanding accounting from basic custodial record-keeping into a analytical management tool. Which of the following best explains why the emergence of joint-stock companies during this era fundamentally transformed the primary scope of accounting beyond traditional bookkeeping?

Show answer & explanation

Answer: The separation of business ownership from management created a demand for independent financial reporting, stewardship accountability, and decision-oriented analysis for external investors.

Answer

The separation of business ownership from management created a demand for independent financial reporting, stewardship accountability, and decision-oriented analysis for external investors.
The correct response highlights that the emergence of joint-stock companies separated ownership from managerial control. This separation necessitated audited financial reports and analytical accounting to assure absentee investors that their capital was being managed effectively, elevating accounting beyond simple transaction recording.

Step-by-Step Solution

1
Analyze the historical evolution of accounting from antiquity to the Industrial Revolution.
Early accounting focused primarily on simple custodial bookkeeping (recording receipts and payments for merchants and estate owners).
Before large corporations existed, owners directly managed their own small businesses or farms.
2
Identify the key organizational change introduced by the Industrial Revolution and joint-stock companies.
Joint-stock corporations led to widespread separation of ownership (shareholders) and control (hired managers).
Capital requirements for large manufacturing and transport enterprises required pooling resources from numerous absentee investors.
3
Evaluate how this structural shift redefined the purpose and scope of financial records.
Accounting evolved beyond clerical bookkeeping into financial reporting, auditing, cost accounting, and managerial decision analysis.
Absentee owners needed reliable, audited financial statements to evaluate management's stewardship and make investment decisions.

Matches

Show answer & explanation

Answer

Proforma Invoice matches the document sent by the principal detailing goods dispatched; Account Sales matches the periodic statement rendered by the agent showing sales, expenses, and net balance; Del Credere Commission matches the extra remuneration for bearing bad debt risk; Consignee matches the agent receiving goods on bailment.
Each consignment term correctly pairs with its unique operational role: Proforma Invoice serves as an informational document sent by the principal; Account Sales summarizes transactions rendered by the agent; Del Credere Commission provides indemnity against bad debts; and the Consignee acts as the selling agent under bailment.

Step-by-Step Solution

1
Identify the document issued at the dispatch of goods by the principal.
Proforma Invoice accompanies the consignment to provide details of goods sent without acting as a sales invoice.
Ownership does not transfer upon dispatch, so a regular invoice is not issued.
2
Identify the financial summary document prepared by the agent.
Account Sales records total sales, expenses paid by consignee, commission earned, and net balance remitted.
It acts as the primary reporting document between consignee and consignor.
3
Identify the specific commission type related to credit sales risk.
Del Credere Commission shifts the burden of bad debts from the consignor to the consignee.
In exchange for higher commission, the agent guarantees collection of debts from buyers.
4
Define the role of the receiving party in a consignment transaction.
Consignee is the agent operating on behalf of the consignor.

Kalu offers to sell a commercial delivery van to Tunde for ₦4,500,000₦4,500,000. Tunde replies offering to buy the van for ₦4,000,000₦4,000,000, which Kalu rejects. Tunde then informs Kalu that he accepts the original price of ₦4,500,000₦4,500,000 and tenders the cash, but Kalu refuses to transfer the van. Which of the following best describes the legal position of the parties?

Show answer & explanation

Answer: No contract is formed because the buyer's counter-offer legally terminated the seller's original offer.

Answer

No contract is formed because the buyer's counter-offer legally terminated the seller's original offer.
Under the law of contract, an acceptance must be unconditional and match all terms of the offer. When the buyer proposed a lower price of ₦4,000,000₦4,000,000, this constituted a counter-offer. A counter-offer operates as a complete legal rejection of the original offer, permanently extinguishing it. Consequently, when the buyer later attempted to accept the original price of ₦4,500,000₦4,500,000, there was no longer an open offer to accept, and no binding contract came into existence.

Step-by-Step Solution

1
Analyze the initial communication
Kalu made a valid offer to sell the delivery van for ₦4,500,000₦4,500,000.
An offer must be a definite proposal made with the intention to contract on specific terms.
2
Evaluate the buyer's response of ₦4,000,000₦4,000,000
Tunde's response constitutes a counter-offer rather than an acceptance.
An acceptance must be unqualified and mirror the exact terms of the offer. Modifying the price creates a counter-offer.
3
Determine the legal effect of a counter-offer
The counter-offer rejects and permanently extinguishes the original offer of ₦4,500,000₦4,500,000.
Under the law of contract (as established in cases such as Hyde v. Wrench), a counter-offer destroys the original offer.
4
Assess the subsequent attempt to accept the original price
Tunde's statement to pay ₦4,500,000₦4,500,000 acts as a new offer to Kalu, which Kalu is free to accept or reject.
Once an offer is destroyed by a counter-offer, it cannot be revived by the offeree.

Calculate the required depreciation adjustment values for the sole trader's final accounts based on the information provided below.

Fill in the blanks below

A sole trader purchased a delivery van for ₦2,000,000\text{₦}2,000,000 on 1 July 2024. On 1 October 2025, an additional delivery van was purchased for ₦1,200,000\text{₦}1,200,000. Depreciation is charged at 20%20\% per annum using the reducing balance method, calculated on a pro-rata basis for partial months of ownership. The accounting year ends on 31 December.

The total depreciation expense debited to the Profit and Loss Account for the year ended 31 December 2025 is , and the Net Book Value of Motor Vehicles presented in the Balance Sheet as at 31 December 2025 is .
Show answer & explanation

Answer

The total depreciation expense for the year ended 31 December 2025 is ₦420,000, and the Net Book Value of Motor Vehicles in the Balance Sheet as at 31 December 2025 is ₦2,580,000.
For the year ended 31 December 2025, depreciation on the first van is calculated at 20%20\% on its opening Net Book Value of ₦1,800,000\text{₦}1,800,000 (giving ₦360,000\text{₦}360,000), while depreciation on the second van purchased on 1 October 2025 is calculated pro-rata for 3 months on its cost of ₦1,200,000\text{₦}1,200,000 (giving ₦60,000\text{₦}60,000). The total P&L charge for 2025 is ₦420,000\text{₦}420,000. The Balance Sheet Net Book Value is total cost (₦3,200,000\text{₦}3,200,000) less total accumulated depreciation (₦620,000\text{₦}620,000), resulting in ₦2,580,000\text{₦}2,580,000.

Step-by-Step Solution

1
Calculate depreciation for the first van for the financial year 2024
Depreciation for 2024 (6 months from 1 July to 31 December) = ₦2,000,000×20%×612=₦200,000\text{₦}2,000,000 \times 20\% \times \frac{6}{12} = \text{₦}200,000. Net Book Value at 31 December 2024 = ₦2,000,000−₦200,000=₦1,800,000\text{₦}2,000,000 - \text{₦}200,000 = \text{₦}1,800,000.
Pro-rata depreciation must be calculated for partial year of purchase under the reducing balance method.
2
Calculate depreciation for the first van for the financial year 2025
Depreciation for 2025 = 20%×₦1,800,000=₦360,00020\% \times \text{₦}1,800,000 = \text{₦}360,000.
Reducing balance method applies the rate to the Net Book Value at the beginning of the financial year (1 January 2025).
3
Calculate pro-rata depreciation for the second van acquired during 2025
Depreciation for 2025 (3 months from 1 October to 31 December) = ₦1,200,000×20%×312=₦60,000\text{₦}1,200,000 \times 20\% \times \frac{3}{12} = \text{₦}60,000.
The second van was owned for only 3 months in 2025, requiring pro-rata computation on its cost.
4
Determine total P&L depreciation expense for 2025 and closing Net Book Value
Total 2025 Depreciation Charge = ₦360,000+₦60,000=₦420,000\text{₦}360,000 + \text{₦}60,000 = \text{₦}420,000. Total Cost of Vehicles = ₦2,000,000+₦1,200,000=₦3,200,000\text{₦}2,000,000 + \text{₦}1,200,000 = \text{₦}3,200,000. Total Accumulated Depreciation = ₦200,000+₦420,000=₦620,000\text{₦}200,000 + \text{₦}420,000 = \text{₦}620,000. Net Book Value as at 31 December 2025 = ₦3,200,000−₦620,000=₦2,580,000\text{₦}3,200,000 - \text{₦}620,000 = \text{₦}2,580,000.
P&L expense is the sum of depreciation charges for all assets for the current year, while Net Book Value reflects total cost less total accumulated depreciation up to the Balance Sheet date.

Ada and Bisi are partners sharing profits and losses in the ratio 3:23:2. On 1st April 2026, they agree to revalue the assets and liabilities of the firm prior to admitting a new partner. The books show: Building (book value ₦200,000\text{₦}200,000) revalued at ₦250,000\text{₦}250,000; Furniture (book value ₦80,000\text{₦}80,000) revalued at ₦70,000\text{₦}70,000; a new Provision for Doubtful Debts of ₦5,000\text{₦}5,000 is to be created; and an unrecorded liability for expenses of ₦15,000\text{₦}15,000 is to be recognized. What is Bisi's share of the revaluation profit or loss?

Show answer & explanation

Answer: ₦8,000\text{₦}8,000 profit

Answer

Bisi's share of the revaluation profit is ₦8,000\text{₦}8,000 profit.
The net revaluation gain is calculated by taking the appreciation of the building (+₦50,000+\text{₦}50,000) and subtracting the depreciation of furniture (−₦10,000-\text{₦}10,000), the new provision for doubtful debts (−₦5,000-\text{₦}5,000), and the unrecorded liability (−₦15,000-\text{₦}15,000), giving a net profit of ₦20,000\text{₦}20,000. Bisi's ratio share is 25\frac{2}{5}, which equals ₦8,000\text{₦}8,000 profit.

Step-by-Step Solution

1
Calculate the revaluation gains and losses for each item
Increase in Building = ₦250,000−₦200,000=+₦50,000\text{₦}250,000 - \text{₦}200,000 = +\text{₦}50,000 (Gain); Decrease in Furniture = ���70,000−₦80,000=−₦10,000\text{���}70,000 - \text{₦}80,000 = -\text{₦}10,000 (Loss); Provision for Doubtful Debts = −₦5,000-\text{₦}5,000 (Loss); Unrecorded Liability = −₦15,000-\text{₦}15,000 (Loss).
Increases in assets are credited to the Revaluation Account as gains, whereas decreases in assets and increases in liabilities are debited as losses.
2
Determine the net revaluation profit or loss
Net Profit = ₦50,000−₦10,000−₦5,000−₦15,000=₦20,000\text{₦}50,000 - \text{₦}10,000 - \text{₦}5,000 - \text{₦}15,000 = \text{₦}20,000.
Summing up the revaluation credits and debits yields a net profit of ₦20,000\text{₦}20,000.
3
Apportion the net revaluation profit to Bisi using the old profit-sharing ratio
Bisi's share = 23+2×₦20,000=25×₦20,000=₦8,000\frac{2}{3+2} \times \text{₦}20,000 = \frac{2}{5} \times \text{₦}20,000 = \text{₦}8,000.
Revaluation gains and losses are credited/debited to existing partners in their old profit-sharing ratio.

Answer: Share Capital Account credited with ���120,000\text{���}120,000 and Share Premium Account credited with ₦30,000\text{₦}30,000

Answer

Share Capital Account credited with ₦120,000\text{₦}120,000 and Share Premium Account credited with ₦30,000\text{₦}30,000
When shares are issued at a premium (issue price higher than nominal value), double-entry principles dictate that Share Capital Account is credited with the total nominal value of shares issued (60,000×₦2.00=₦120,00060,000 \times \text{₦}2.00 = \text{₦}120,000) and the capital surplus is credited to Share Premium Account (60,000×₦0.50=₦30,00060,000 \times \text{₦}0.50 = \text{₦}30,000).

Step-by-Step Solution

1
Calculate the total nominal share capital value.
60,000 shares×₦2.00=₦120,00060,000 \text{ shares} \times \text{₦}2.00 = \text{₦}120,000
Share capital is always recorded at its face (nominal) value.
2
Calculate the premium per share and total share premium.
Premium per share = ₦2.50−₦2.00=₦0.50\text{₦}2.50 - \text{₦}2.00 = \text{₦}0.50; Total Share Premium = 60,000×₦0.50=₦30,00060,000 \times \text{₦}0.50 = \text{₦}30,000
The excess amount received over the nominal value represents share premium.

Following a national environmental audit in Nigeria, an inter-agency task force is deployed to combat two distinct ecological hazards: coastal mangrove degradation from petroleum leaks in the Niger Delta and rapid land degradation in the Sahelian northern borderlands. Which of the following correctly identifies the federal agency specifically mandated to manage the petroleum spills, alongside the primary human activity driving desertification in the Sahelian zone?

Show answer & explanation

Answer: National Oil Spill Detection and Response Agency (NOSDRA); excessive fuel-wood harvesting and overgrazing removing protective vegetal cover

Answer

National Oil Spill Detection and Response Agency (NOSDRA); excessive fuel-wood harvesting and overgrazing removing protective vegetal cover
The correct option correctly identifies NOSDRA as the specialized federal agency established to lead oil spill detection and response in Nigeria's petroleum-producing zones. It also accurately pinpoints fuel-wood harvesting and overgrazing as the major human activities stripping vegetal cover in the Sahel, directly driving desert expansion in northern Nigeria.

Step-by-Step Solution

1
Identify the primary agency responsible for oil spill detection and response in Nigeria.
NOSDRA (established in 2006) holds the specific legal mandate for oil spill monitoring and containment in Nigeria, distinguishing it from general enforcement agencies like NESREA.
Regulatory frameworks assign targeted petroleum sector hazards to specialized statutory bodies.
2
Analyze the primary human causes of desertification in northern Nigeria.
Overgrazing by livestock herds, coupled with extensive fuel-wood cutting, removes the sparse vegetation cover of the Sahelian belt, exposing topsoil to aeolian erosion and advancing desert conditions.
Anthropogenic pressure on fragile dryland ecosystems accelerates land degradation beyond natural climate variability.
3
Synthesize the agency mandate with the regional ecological hazard driver.
The correct combination pairs NOSDRA with excessive fuel-wood harvesting and overgrazing.
Cross-matching spatial hazard drivers with environmental governance structures confirms the correct option.

Since 15∘15^\circ of longitude corresponds to 1 hour of time difference, 45∘45^\circ equals 3 hours (45÷15=345 \div 15 = 3). Because City B lies further east than City A, time is ahead. Adding 3 hours to 1:00 PM yields 4:00 PM.

Step-by-Step Solution

1
Calculate the difference in longitude between the two locations
60∘E−15∘E=45∘60^\circ\text{E} - 15^\circ\text{E} = 45^\circ
Both locations are in the Eastern Hemisphere, so subtract the smaller longitude from the larger longitude.
2
Convert the angular difference into time difference
45∘÷15∘ per hour=3 hours45^\circ \div 15^\circ\text{ per hour} = 3\text{ hours}
The Earth rotates 15∘15^\circ in 1 hour (360∘360^\circ in 24 hours).
3
Adjust local time based on direction of movement
1:00 PM +3 hours=4:00 PM+ 3\text{ hours} = 4:00\text{ PM}
Eastward movement results in time gain (East-Gain, West-Loss), so add the time difference to the known time.

Answer

Hub-and-Spoke Network pairs with central traffic consolidation; Linear Corridor pairs with sequential node links along a primary axis; Grid Network pairs with high route redundancy; Point-to-Point Network pairs with direct links between origins and destinations.
In transport geography, network topologies reflect structural accessibility and flow efficiency: Hub-and-Spoke networks centralize movement through a central node; Linear Corridors arrange settlements sequentially along a main axis; Grid Networks provide high route redundancy through intersecting paths; Point-to-Point networks establish direct transit between pairs of origins and destinations.

Step-by-Step Solution

1
Examine the spatial layout and operational definition of each transport network topology.
Hub-and-Spoke systems route flows through a central junction; Linear corridors follow a single axis; Grid networks consist of intersecting multidirectional routes; Point-to-Point networks link nodes directly.
In transport geography, topological structures define how nodes are linked, affecting network accessibility and routing efficiency.
2
Pair each topology term with its corresponding characteristic description.
Hub-and-Spoke matches traffic consolidation through a central node; Linear Corridor matches sequential linkage along a main axis; Grid Network matches high route redundancy; Point-to-Point matches direct origin-destination connections.
Connecting spatial definitions to their correct network terminology demonstrates mastery of transportation connectivity principles.

Items

Contour terracing
Afforestation belts (Shelterbelts)
Crop rotation with leguminous plants
Environmental Impact Assessment (EIA)

Matches

Show answer & explanation

Answer

Contour terracing matches with mitigating water erosion on steep slopes by reducing surface runoff velocity; Afforestation belts match with checking wind erosion and desert encroachment in dry savanna and Sahel zones; Crop rotation with leguminous plants matches with biologically restoring soil nitrogen content and breaking crop pest cycles; Environmental Impact Assessment matches with systematically evaluating potential ecological consequences prior to project execution.
Each conservation technique is correctly matched to its functional classification: mechanical water erosion control (terracing on slopes), biological wind barrier control (shelterbelts in drylands), biological nutrient replenishment (leguminous rotation), and administrative/regulatory evaluation (EIA).

Step-by-Step Solution

1
Analyze mechanical soil conservation techniques on sloped topography.
Identify that contour terracing alters hill slopes into stepped platforms to decrease surface runoff speed and prevent sheet/gully wash.
Terracing specifically targets slope gradient and water velocity.
2
Examine biological and wind erosion management techniques suitable for semi-arid zones.
Connect afforestation shelterbelts to windbreak functions in northern drylands like the Sahel.
Tree barriers break the force of harmattan winds and check sand dune movement.
3
Evaluate agricultural soil conservation methods.
Link leguminous crop rotation to biological nitrogen fixation and pest management.
Rhizobium bacteria in legumes fix atmospheric nitrogen, enhancing nutrient cycling.
4
Differentiate administrative and policy management tools from physical conservation techniques.
Pair Environmental Impact Assessment with pre-project ecological impact predictions.
EIA acts as a preventative planning requirement rather than a physical soil management activity.

Question 3677Question →

In highland areas of West Africa such as the Mandara Mountains and parts of the Jos Plateau, traditional agrarian societies historically developed labor-intensive hill terracing, organic manuring, and permanent cultivation rather than bush fallowing. Which set of geographic factors best explains this local intensification of land use?

Show answer & explanation

Answer: High population density combined with defensive isolation in rugged terrain that restricted spatial expansion into lowland bush

Answer

The primary cause for intensive hill terracing and permanent land use in these West African highlands was high population density confined to rugged, defensible terrain, which restricted access to surrounding lowlands and compelled land-saving agricultural intensification.
Intensive terraced agriculture and continuous manuring are classic land-saving agricultural strategies. In historical West Africa, rugged highland refuges provided defense against external aggression but limited available arable land. When population pressure increased inside these geographically confined spaces, farmers could not practice extensive bush fallowing; instead, they were forced to invest heavy labor into slope terracing and soil conservation to maintain permanent fields.

Step-by-Step Solution

1
Analyze the spatial and environmental characteristics of West African highland agricultural systems.
Identified that hill terracing, organic manuring, and zero-fallow farming are intensive responses to severe land land boundaries and steep slopes.
Intensive land use occurs where land is scarce relative to population and cannot be expanded horizontally.
2
Evaluate the human-environment interaction drivers.
Recognized that historical refuge settlements in mountainous areas (for defense against lowland conflicts) created localized high population density.
Defensive isolation prevented farmers from practicing extensive bush fallowing across wider lowland areas.
3
Synthesize the socio-spatial factors with agricultural adaptation theory (Boserupian intensification).
Concluded that high population pressure within restricted physical boundaries necessitates labor-intensive soil conservation techniques.
Boserup's theory demonstrates that population concentration drives transitions from extensive fallow systems to intensive permanent cropping.

Question 3678Question →

In population geography, various factors compel individuals to relocate from their place of origin or attract them to a new destination. Which of the following is classified as a push factor triggering rural-to-urban migration in West Africa?

Show answer & explanation

Answer: Frequent crop failures resulting from persistent drought and severe soil degradation

Answer

Frequent crop failures resulting from persistent drought and severe soil degradation
The correct answer identifies frequent crop failures caused by drought and soil degradation as a push factor. Push factors encompass negative, adverse, or compelling circumstances at the origin area—such as environmental collapse, unemployment, or poor agricultural yield—that compel individuals to move away.

Step-by-Step Solution

1
Define push factors in population geography
Push factors are adverse or unfavorable conditions existing at a person's place of origin that compel or drive them to migrate away.
Distinguishing origin-based negative pressures (push) from destination-based positive attractions (pull) is fundamental to migration theory.
2
Evaluate the options against push factor criteria
Agricultural failure due to drought and degraded soil directly threatens rural livelihoods at the origin, forcing inhabitants to seek alternatives elsewhere.
Environmental degradation and food insecurity act as classic rural push factors driving outward movement.

Cheque drawn and issued to a supplier but not yet cleared by the bank
Customer cheque deposited into the bank but not yet credited on the bank statement

Matches

Show answer & explanation

Answer

Standing order payments are credited to the Adjusted Cash Book; direct customer deposits are debited to the Adjusted Cash Book; issued cheques not yet cleared are treated as unpresented cheques in the Bank Reconciliation Statement; and deposited cheques not yet credited are treated as uncredited deposits in the Bank Reconciliation Statement.
Standing orders represent unrecorded cash payments and are credited to the Adjusted Cash Book. Direct customer deposits represent unrecorded cash receipts and are debited to the Adjusted Cash Book. Unpresented cheques and uncredited deposits are timing differences and are placed in the Bank Reconciliation Statement.

Step-by-Step Solution

1
Identify items that require Cash Book adjustment
Standing orders and direct deposits are unrecorded bank transactions that must be entered into the Cash Book before reconciliation.
The Cash Book must reflect all actual bank transactions (charges, interest, direct debits, standing orders, and credit transfers) prior to reconciling timing differences.
2
Determine debit/credit entries for Adjusted Cash Book items
Direct customer deposits increase cash (debit entry); standing order insurance payments decrease cash (credit entry).
Cash Book follows double-entry rules where cash receipts are debited and cash payments are credited.
3
Identify timing differences for the Bank Reconciliation Statement
Unpresented cheques and uncredited deposits are placed directly into the Bank Reconciliation Statement.
Timing differences occur due to time lags in bank processing and are already recorded in the Cash Book, so they do not alter the Adjusted Cash Book balance.

Key Concept

Distinguishing between items that adjust the Cash Book (unrecorded transactions and cash book errors) and items that belong in the Bank Reconciliation Statement (timing differences such as unpresented cheques and uncredited lodgements).

Match each physical region of Nigeria listed on the left with its corresponding geological structure and drainage characteristic on the right.

Click a left item, then click its matching right item

Items

Jos Plateau
Biu Plateau
Sokoto Plains
Cross River Basin

Matches

Show answer & explanation

Answer

Jos Plateau corresponds to the high basement complex dome with radial drainage; Biu Plateau corresponds to the basaltic volcanic plateau forming a watershed for Hawal and Gongola rivers; Sokoto Plains corresponds to the sedimentary basin with cuestas drained by the Rima system; and Cross River Basin corresponds to the structural lowland trough drained from the Oban Hills and Western Cameroon highlands.
Each physical region in Nigeria possesses a unique combination of rock geology and drainage patterns: the Jos Plateau is a basement dome with radial drainage; the Biu Plateau is a volcanic basaltic upland; the Sokoto Plains consist of sedimentary cuestas drained by the Rima; and the Cross River Basin is a lowland trough fed by the Oban Hills and Cameroon highlands.

Step-by-Step Solution

1
Identify the drainage and geological features of the Jos Plateau.
Recognize that the Jos Plateau is an elevated basement complex mass from which rivers flow outwards in all directions (radial pattern) toward the Niger, Benue, and Lake Chad basins.
Topographical elevation and crystalline rock structure make it the country's primary hydrographic apex.
2
Identify the origin and drainage traits of the Biu Plateau.
Determine that unlike the basement complex plates, Biu is a basaltic volcanic plateau feeding regional tributaries like River Hawal.
Cenozoic volcanic activity created distinct basalt caprocks distinguishing it from granitic uplands.
3
Analyze the rock structure and landforms of the Sokoto Plains.
Associate the northwestern plains with Cretaceous-Tertiary sedimentary strata, cuesta ridges, and the Rima-Sokoto river network.
The Iullemmeden sedimentary basin structure dictates the low-gradient dip slopes and cuesta scarp topography.
4
Evaluate the coastal/southeastern interior relief of the Cross River Basin.
Link the Cross River depression to sedimentary infill bounded by the Oban Hills and Cameroon mountain ranges.
High rainfall and elevated source ranges feed heavily silted streams flowing into the Cross River estuary.
