Question 6201Question

Unlike private sector accounting, which primarily measures business profitability and owners' equity, what is the primary objective of public sector accounting?

Show answer & explanation

Answer: To demonstrate stewardship, public accountability, and compliance with statutory appropriations

Answer

To demonstrate stewardship, public accountability, and compliance with statutory appropriations
The fundamental goal of public sector accounting is to ensure that revenue collected and expenditure incurred are properly accounted for, providing full accountability and demonstrating compliance with parliamentary votes and statutory regulations.

Step-by-Step Solution

1
Identify the fundamental purpose of public financial administration
Public sector accounting serves public authorities, legislature, and citizens by recording the collection and spending of public funds according to approved budgets.
Unlike private enterprises, government revenue is raised through taxation and statutory allocations to fulfill public policy objectives without a profit-making motive.
2
Evaluate the key features of public sector financial reporting
Accounting systems in the public sector emphasize fund accounting, legislative budget control (vote accounting), stewardship, and legal compliance.
Public officials must account for their stewardship of public resources to prevent mismanagement and ensure spending aligns with legislative appropriations.

Question 6207Question

Urban planners in a developing nation observe that an unprecedented influx of agricultural workers into the primate city has created severe housing shortages, traffic congestion, and environmental degradation. Which planning initiative directly addresses the primary push factor responsible for this urban growth trend?

Show answer & explanation

Answer: Developing rural infrastructure, agro-processing facilities, and social amenities in agrarian communities

Answer

Developing rural infrastructure, agro-processing facilities, and social amenities in agrarian communities
Addressing rural push factors—such as lack of rural amenities, low agricultural profitability, and inadequate infrastructure—improves living standards in countryside communities, thereby reducing the driving force behind mass rural-to-urban migration and relieving urban settlement pressures.

Step-by-Step Solution

1
Identify the core problem described in the stem
The problem is rapid urbanization caused by rural-to-urban migration from agricultural regions into a central city.
Understanding the demographic mechanism helps isolate whether push factors (origin conditions) or pull factors (destination conditions) need targeting.
2
Distinguish between push and pull factors of migration
Push factors are adverse rural conditions (e.g., poor infrastructure, lack of employment, low agricultural yields), whereas pull factors are perceived urban advantages.
The question specifically asks for an initiative targeting the primary push factor driving migrants away from rural areas.
3
Evaluate the option choices against push factor mitigation
Improving rural socio-economic conditions directly eliminates rural push factors, slowing down distress-driven migration to urban centers.
Targeting origin rural communities addresses the root cause of excessive urban settlement growth.

Question 6208Question

To effectively combat severe gully erosion causing massive land degradation in the sedimentary terrain of Anambra State in South-Eastern Nigeria, environmental managers require an integrated conservation strategy. Which of the following combinations of methods offers the most sustainable long-term solution to stabilize active gully heads and prevent further catchment runoff damage?

Show answer & explanation

Answer: Construction of check dams and gabions combined with catchment afforestation and bamboo planting along gully floors

Answer

The most effective long-term conservation strategy combines structural engineering measures like check dams and gabions with biological measures such as catchment afforestation and bamboo planting along gully channels.
The correct answer combines mechanical controls (check dams and gabions) to slow water flow and trap sediment with biological controls (afforestation and deep-rooting bamboo) to permanently anchor soil particles and restore ecological balance in high-rainfall gully regions.

Step-by-Step Solution

1
Analyze the environmental hazard and geographic context
Identified severe gully erosion in high-rainfall sedimentary terrain (South-East Nigeria) requiring runoff reduction and slope stabilization.
Effective conservation requires matching physical terrain challenges with integrated mechanical and biological methods.
2
Evaluate mechanical soil and water conservation techniques
Check dams and gabions act as physical barriers that trap sediment and dissipate hydraulic energy of surface runoff.
Lowering runoff energy halts active headward gully expansion.
3
Evaluate biological re-vegetation methods
Afforestation and bamboo cultivation provide dense root networks that bind soil particles and enhance infiltration.
Vegetative cover prevents splash erosion and anchors unstable slopes permanently.

Question 6209Question

In Southeastern Nigeria, gully erosion poses a severe environmental hazard. What is the correct sequential order of the stages in the development of a gully, from initial land disturbance to catastrophic collapse?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with vegetation removal, followed by surface runoff forming micro-rills, which deepen into incised gullies, and culminates in massive sidewall collapse and severe structural land loss.
The erosion process follows a logical morpho-dynamic progression: human or natural land clearing first removes protective vegetation, allowing concentrated surface runoff to carve rills. Continuous concentrated water flow deepens these rills into gullies, which eventually undergo mass failure and sidewall slumping due to basal under-cutting and sub-surface seepage.

Step-by-Step Solution

1
Identify the primary trigger initiating soil exposure.
Land clearing and deforestation remove protective plant cover.
Without plant canopy and roots, soil aggregates break down easily under rain impact.
2
Trace the initial runoff response on bare soil slopes.
Surface runoff gathers momentum and carves small rills.
Water flows downhill along paths of least resistance, detaching topsoil particles.
3
Examine channel deepening under continuous rainfall.
Rills expand vertically and laterally into deep gullies.
Concentrated volume and velocity of water enhance hydraulic scouring along the channel floor.
4
Determine the final stage of structural collapse.
Under-cutting and seepage cause massive gully wall collapse.
Basal erosion and groundwater piping destabilize side slopes, triggering gravitational slumping.

Question 6210Question

The River Niger exhibits an unusual boomerang-shaped course, rising just 240 kilometres from the Atlantic Ocean in the Fouta Djallon highlands of Guinea, yet flowing northeastward into the arid Saharan margin before bending sharply south to discharge into the Gulf of Guinea. Which of the following geological and hydrological phenomena best explains this anomalous flow path?

Show answer & explanation

Answer: The capture of an ancient endorheic upper inland river system by a lower coastal river eroding headward from the Gulf of Guinea

Answer

The capture of an ancient endorheic upper inland river system by a lower coastal river eroding headward from the Gulf of Guinea
The unique course of the River Niger (the 'elbow of capture' near Bourem/Timbuktu) is the result of stream piracy (river capture). Historically, the Upper Niger originated in the Fouta Djallon and discharged into a landlocked inland lake (Lake Juf) in the Sahara. Meanwhile, a lower coastal stream eroding headward from the Gulf of Guinea cut through the highlands at Tosaye and captured the inland lake waters, diverting the entire upper river system southward into the Atlantic Ocean.

Step-by-Step Solution

1
Analyze the geological history of the River Niger's course.
Identified that the River Niger is composed of two distinct historical sections: the Upper Niger and the Lower Niger.
Understanding river evolution helps explain why a river rising close to the coast flows deep inland before returning south.
2
Evaluate the mechanism of River Capture (Stream Piracy) at Tosaye.
The Upper Niger used to empty into an endorheic (inland drainage) lake near Timbuktu. The Lower Niger eroded headward until it breached the sill at Tosaye, capturing the upper basin.
Headward erosion by a energetic coastal stream capturing an inland system is the established geological explanation for the River Niger's elbow of capture.

Question 6211Question

On a topographical map, a series of V-shaped contour lines point towards lower elevation values as they extend across the landscape. Which of the following relief features is represented by this contour pattern?

Show answer & explanation

Answer: Spur

Answer

Spur
V-shaped contour lines whose apexes point towards lower elevation represent a spur, which is a tongue of elevated land projecting downwards from a main hill or ridge. Conversely, when V-shapes point upstream towards higher elevation, they indicate a river valley.

Step-by-Step Solution

1
Analyze the contour line geometry described in the prompt
The contour lines form V-shapes pointing towards decreasing (lower) elevation.
Understanding the orientation of V-shaped contours relative to elevation is key to identifying linear relief features.
2
Distinguish between a spur and a valley using contour apex orientation
Apexes pointing upstream (higher elevation) represent valleys, whereas apexes pointing downstream/down-slope (lower elevation) represent spurs.
A spur is a salient tongue of high ground sloping downwards between two valleys.

Question 6213Question

Inside a Stevenson screen at a meteorological station, a dry-bulb thermometer reads 28C28^\circ\text{C} while a wet-bulb thermometer reads 22C22^\circ\text{C}, yielding a wet-bulb depression of 6C6^\circ\text{C}. Which atmospheric variable is determined using this temperature difference, and which weather instrument would be mistakenly selected if an observer attempted to measure this variable by recording atmospheric pressure instead?

Show answer & explanation

Answer: Relative humidity is determined from the temperature difference; a barometer would be mistakenly selected because it measures atmospheric pressure.

Answer

Relative humidity is derived from the depression of the wet-bulb thermometer (28C22C=6C28^\circ\text{C} - 22^\circ\text{C} = 6^\circ\text{C}) using psychrometric tables. Mistakenly using a barometer targets atmospheric pressure instead of atmospheric moisture.
Relative humidity is the ratio of actual water vapour present in the air to the maximum amount the air can hold at that temperature. It is calculated using the depression of the wet bulb (the difference between dry-bulb and wet-bulb thermometer readings). A barometer is designed specifically to measure atmospheric pressure, so choosing a barometer to assess atmospheric humidity represents an instrument-parameter mismatch.

Step-by-Step Solution

1
Identify the weather element evaluated by a wet-and-dry bulb psychrometer.
The dry-bulb thermometer records ambient air temperature (28C28^\circ\text{C}), while evaporation from the moist muslin sheath lowers the wet-bulb temperature to 22C22^\circ\text{C}.
The rate of evaporation and resulting cooling (wet-bulb depression of 6C6^\circ\text{C}) depends directly on the relative humidity of the air.
2
Identify the mistaken instrument association.
A mercury or aneroid barometer measures atmospheric pressure (force exerted per unit area by the atmosphere).
Selecting a barometer when intending to measure relative humidity confuses pressure measurement with atmospheric moisture measurement.

Question 6214Question

On a topographical map, a hillside shows contour lines that are densely packed near the hilltop at higher elevations and gradually become widely spaced towards the foot of the hill at lower elevations. Which type of relief slope does this contour pattern represent?

Show answer & explanation

Answer: Concave slope

Answer

Concave slope
The correct answer is a concave slope because contour lines that are closely spaced near the crest and widely spaced towards the base represent a steep upper slope transitioning into a gentle lower slope, which forms an inward-curving profile.

Step-by-Step Solution

1
Analyze the contour line spacing at higher elevations.
Densely packed contours indicate a steep gradient near the top of the hill.
When contour lines are close together, elevation changes rapidly over a short horizontal distance.
2
Analyze the contour line spacing at lower elevations.
Widely spaced contours indicate a gentle gradient near the base of the hill.
When contour lines are far apart, elevation changes gradually over a longer horizontal distance.
3
Combine the gradient observations to identify the slope profile.
A slope that curves inward—steep near the summit and gentle near the base—is defined as a concave slope.
This physical shape corresponds to a concave profile.

Question 6215Question

Koko Nigeria Limited was registered with an authorized share capital of 1,000,000 ordinary shares of ₦1.00 each. The directors issued 600,000 ordinary shares to the public at par, all of which were fully subscribed and allotted. A call of ₦0.80 per share was subsequently made. All shareholders paid the call in full except for a holder of 25,000 shares who failed to pay. What is the paid-up share capital of Koko Nigeria Limited?

Show answer & explanation

Answer: ₦460,000

Answer

₦460,000
The paid-up capital is the total money received from shareholders for shares called up. Subtracting calls in arrears of ₦20,000 (25,000 shares × ₦0.80) from called-up capital of ₦480,000 (600,000 shares × ₦0.80) yields ₦460,000.

Step-by-Step Solution

1
Calculate called-up capital
600,000 shares × ₦0.80 = ₦480,000
Called-up capital represents the portion of issued share capital that the company has requested shareholders to pay.
2
Calculate calls in arrears
25,000 shares × ₦0.80 = ₦20,000
Calls in arrears represent the amount requested by the company that shareholders have defaulted on.
3
Calculate paid-up capital
₦480,000 - ₦20,000 = ₦460,000
Paid-up capital is equal to called-up capital minus calls in arrears.

What is the amount of Capital (in \text{₦}) to be credited in the General Journal?

Show answer & explanation

Answer: 500000

Answer

The Capital to be credited in the General Journal is 500,000\text{₦}500,000.
The General Journal opening entry records total assets of 750,000\text{₦}750,000 on the debit side and total liabilities of 250,000\text{₦}250,000 on the credit side. The balancing amount credited to the Capital Account is computed as Capital=AssetsLiabilities=750,000250,000=500,000\text{Capital} = \text{Assets} - \text{Liabilities} = \text{₦}750,000 - \text{₦}250,000 = \text{₦}500,000.

Step-by-Step Solution

1
Calculate total assets by adding all asset balances
Total Assets = 450,000+180,000+90,000+30,000=750,000\text{₦}450,000 + \text{₦}180,000 + \text{₦}90,000 + \text{₦}30,000 = \text{₦}750,000
Opening entries require debiting all assets of the business.
2
Calculate total liabilities by adding all external obligations
Total Liabilities = 140,000+110,000=250,000\text{₦}140,000 + \text{₦}110,000 = \text{₦}250,000
Opening entries require crediting all liabilities owed to external parties.
3
Deduct total liabilities from total assets to determine the opening capital
Capital = 750,000250,000=500,000\text{₦}750,000 - \text{₦}250,000 = \text{₦}500,000
According to the fundamental accounting equation, Capital=Total AssetsTotal Liabilities\text{Capital} = \text{Total Assets} - \text{Total Liabilities}.

Key Concept

Opening entries in the General Journal (Journal Proper) establish the initial accounting records of a business by recording assets as debits, liabilities as credits, and balancing the entry by crediting Capital using Capital=AssetsLiabilities\text{Capital} = \text{Assets} - \text{Liabilities}.

Matches

Show answer & explanation

Answer

Suburban spillover matches with centrifugal dispersion along transport arteries; Urban primacy matches with asymmetrical national investment in a single metropolis; Spatial segregation matches with exorbitant inner-city land pricing driving informal marginal settlement; Hyper-urbanization matches with migration outpacing formal industrial job creation.
Each urban geography phenomenon is paired strictly with its defining spatial or socioeconomic driver. Suburban spillover is driven by centrifugal transport-led growth; urban primacy stems from skewed centralized capital allocation; spatial segregation/squatting results from exclusionary urban land pricing; and hyper-urbanization leads to informal involution when industrial labor markets fail to keep pace with influxes.

Step-by-Step Solution

1
Analyze Suburban spillover and counter-urbanization fringe growth
Identify that decentralization of manufacturing and transit corridor growth drives spatial expansion outward.
Decongestive outward growth requires improved transportation networks and industrial relocation outside crowded urban cores.
2
Examine Urban primacy and primate city consolidation
Link primacy to macroeconomic centralization where one city dominates urban hierarchy disproportionately.
Primate cities emerge when economic investment, federal infrastructure, and administrative power are concentrated overwhelmingly in one location.
3
Evaluate Spatial segregation and informal peripheral accretion
Connect land pricing mechanisms with informal squatter settlements on ecological fringes.
Inability of low-income migrants to enter formal land markets forces urban squatting on marginal, unprotected terrain.
4
Examine Hyper-urbanization and urban involution
Relate demographic growth uncoupled from industrial growth to informal sector absorption.
Urban involution describes economic stagnation where surplus rural labor flows into informal micro-enterprises rather than industrial wage jobs.

The Sales Ledger Control Account of Chidubem Trading Enterprise showed a debit balance of 320,000\text{₦}320,000 before ledger reconciliation. An investigation of the accounting records revealed the following errors:
1. Sales returns journal total of 8,500\text{₦}8,500 was debited to the Sales Ledger Control Account.
2. Discount allowed amounting to 4,500\text{₦}4,500 was omitted entirely from the Sales Ledger Control Account.
3. A credit sale of 12,000\text{₦}12,000 was posted to the credit side of the Sales Ledger Control Account.

What is the corrected balance of the Sales Ledger Control Account after making the necessary adjustments?

Show answer & explanation

Answer: ₦322,500

Answer

₦322,500
The unadjusted debit balance of ₦320,000 must be adjusted for all three errors. Sales returns debited instead of credited require a credit adjustment of 2×8,500=17,0002 \times \text{₦}8,500 = \text{₦}17,000. Omitted discount allowed requires a credit adjustment of ₦4,500. A credit sale credited instead of debited requires a debit adjustment of 2×12,000=24,0002 \times \text{₦}12,000 = \text{₦}24,000. Performing the net calculation: 320,00017,0004,500+24,000=322,500\text{₦}320,000 - \text{₦}17,000 - \text{₦}4,500 + \text{₦}24,000 = \text{₦}322,500.

Step-by-Step Solution

1
Calculate the adjustment for misplaced sales returns.
Credit adjustment of ₦17,000
Sales returns reduce debtors (credit side). Debiting ₦8,500 requires a credit of ₦17,000 (₦8,500 to cancel the error plus ₦8,500 for correct entry).
2
Calculate the adjustment for omitted discount allowed.
Credit adjustment of ₦4,500
Discount allowed reduces total debtors and must be credited to the Sales Ledger Control Account.
3
Calculate the adjustment for misplaced credit sale.
Debit adjustment of ₦24,000
Credit sales increase debtors (debit side). Crediting ₦12,000 requires a debit of ₦24,000 (₦12,000 to cancel the error plus ₦12,000 for correct entry).
4
Compute the corrected balance.
₦320,000 - ₦17,000 - ₦4,500 + ₦24,000 = ₦322,500

Question 6219Question

According to Von Thünen's model of agricultural location, land use intensity and spatial arrangement around a central market are governed by land rent and transportation costs per unit weight. Arrange the following agricultural land-use activities in sequence from the innermost zone (closest to the market center) to the outermost zone (furthest from the market center).

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct spatial sequence from innermost zone to outermost zone is: (1) Intensive market gardening and commercial dairying, (2) Forestry and fuelwood production, (3) Intensive field crop farming without fallow periods, and (4) Extensive livestock grazing and ranching.
In Von Thünen's model, land rent decreases with distance from the market center while transportation costs increase. Intensive market gardening and dairying generate high economic rent and produce perishable goods, placing them in Zone 1. Forestry occupies Zone 2 because heavy firewood and timber incur extreme freight costs per mile. Intensive crop farming occupies Zone 3 on moderately priced land. Extensive livestock grazing requires vast land areas with low economic rent, placing it in the outermost zone (Zone 4).

Step-by-Step Solution

1
Analyze economic rent and transport cost principles in spatial agricultural distribution.
Activities producing highly perishable goods or having high yield value per unit area occupy land closest to the central city.
Proximity minimizes spoilage and maximizes economic return where land rent is highest.
2
Assign the most perishable and intensive farming system to Zone 1.
Intensive market gardening and dairying occupy the innermost ring.
Fresh vegetables and fluid milk require immediate urban access.
3
Determine the placement of heavy, high-bulk commodities.
Forestry and fuelwood occupy Zone 2.
In pre-industrial/classic economic models, wood transport costs are extremely high due to heavy bulk.
4
Sequence arable crop cultivation and extensive animal production based on land rent tolerance.
Crop farming without fallow occupies Zone 3, while extensive livestock grazing occupies Zone 4.
Livestock grazing requires vast areas of cheap land where economic rent is lowest, and livestock can walk to market.

Question 6220Question

In regions prone to severe land degradation, such as Southeastern Nigeria, water erosion progresses through distinct mechanical stages. Arrange the following stages of water-induced soil erosion in the correct sequence from the initial raindrop impact to the final advanced landscape destruction.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of water erosion stages is: Raindrop impact dislodging soil aggregates (Splash erosion) → Removal of a thin, uniform surface layer of soil by unchanneled runoff (Sheet erosion) → Formation of small, narrow micro-channels in the soil by concentrated flow (Rill erosion) → Carving of deep, steep-sided trenches that permanently alter the landscape (Gully erosion).
Soil erosion by water follows a progressive sequence: splash erosion dislodges fine particles upon raindrop impact; sheet erosion strips a thin layer of topsoil via unchanneled surface runoff; rill erosion forms small, scour-cut channels as runoff concentrates; and gully erosion represents the mature, catastrophic deepening of these channels into un-tillable ravines.

Step-by-Step Solution

1
Identify the initial physical trigger of water-induced erosion.
Raindrop impact dislodges soil aggregates through splash erosion.
Kinetic energy breaks down surface soil structural stability before water accumulates as surface runoff.
2
Determine the effect of unchanneled overland surface flow.
Sheet erosion strips a thin, uniform topsoil layer across the slope.
Water flows as a continuous thin film across smooth ground prior to concentrating into channels.
3
Trace the consequence of runoff concentrating into micro-pathways.
Rill erosion creates shallow micro-channels.
Increased hydraulic volume and shear stress cut temporary miniature channels into the ground.
4
Identify the terminal stage of severe water erosion channel expansion.
Gully erosion carves deep, broad trenches and ravines.
Rills expand through continuous scouring, side-wall slumping, and headward erosion into massive relief features.
