Question 13301Question →

Babatunde was engaged as a general mercantile agent for a manufacturing firm. Contrary to the firm's express written instruction to sell goods solely on a cash basis, Babatunde sold a shipment of goods on credit to a third-party buyer who subsequently defaulted on payment. Under the Law of Agency, which of the following statements correctly describes the legal rights and liabilities of the parties?

The firm is bound to the third party if credit sales fall within the customary authority of a general agent, but Babatunde is liable to compensate the firm for breaching his duty of obedience.

The contract with the third party is automatically void because Babatunde breached a fundamental condition of his agency appointment.

Babatunde becomes personally and exclusively liable to the third party for the contractual debt, relieving the firm of all obligations.

The firm can repudiate the transaction without liability to the third party, and Babatunde is exempt from indemnifying the firm because he acted without malice.

Show answer & explanation

Answer: The firm is bound to the third party if credit sales fall within the customary authority of a general agent, but Babatunde is liable to compensate the firm for breaching his duty of obedience.

Answer

The firm is bound to the third party if credit sales fall within the customary authority of a general agent, but Babatunde is liable to compensate the firm for breaching his duty of obedience.

Under the Law of Agency, a general agent possesses customary authority to bind the principal in transactions typical of that trade. Private or secret limitations imposed by the principal (such as selling for cash only) do not bind third parties who deal with the agent without knowledge of the restriction. Therefore, the contract remains valid and binding on the principal. However, as between the principal and the agent, the agent owes a primary legal duty to obey all lawful directions. By disobeying the explicit instruction to sell only for cash, the agent breaches this duty and is legally bound to indemnify the principal for any resulting financial loss.

Step-by-Step Solution

Analyze the relationship and authority between the principal (firm), agent (Babatunde), and third party.

Babatunde is a general agent. General agents possess customary/apparent authority to perform acts usual in that line of business.

Third parties dealing in good faith are entitled to rely on the apparent authority of a general agent unless they have notice of internal restrictions.

Determine the legal position between the principal and the third party.

The principal is legally bound by the contract created with the third party.

Secret or internal instructions restricting authority do not affect third parties who relied on the agent's customary authority.

Determine the legal position between the principal and the agent.

Babatunde is liable to indemnify the principal for the financial loss suffered from the buyer's default.

An agent owes a strict duty of obedience to carry out the principal's lawful express instructions; failure to do so constitutes a breach of duty.

Question 13302Question →

The central bank of a country provides the following monetary statistics for a given financial period:

- Currency in circulation outside commercial banks: $\text{N}420\text{ billion}$
- Demand deposits with commercial banks: $\text{N}980\text{ billion}$
- Vault cash held by commercial banks: $\text{N}90\text{ billion}$
- Savings deposits: $\text{N}650\text{ billion}$
- Time deposits: $\text{N}350\text{ billion}$

Based on these data, what is the total broad money supply ( $M_2$ ) in this economy in billions of Naira?

Show answer & explanation

Answer: 2400

Answer

The total broad money supply (

M_2

) in the economy is

2,400\text{ billion Naira}

Broad money supply (

M_2

) includes narrow money (

M_1

) plus quasi-money (savings deposits and time deposits).

M_1

is calculated as currency outside banks (

420\text{ billion Naira}

) plus demand deposits (

980\text{ billion Naira}

), totaling

1,400\text{ billion Naira}

. Adding savings deposits (

650\text{ billion Naira}

) and time deposits (

350\text{ billion Naira}

) yields

M_2 = 1,400 + 650 + 350 = 2,400\text{ billion Naira}

. Commercial bank vault cash is excluded as it is an internal reserve not available in active public circulation.

Step-by-Step Solution

Calculate Narrow Money (

M_1

)

M1 = 420 + 980 = 1,400 billion Naira

M1 consists of currency in circulation outside commercial banks and demand deposits. Vault cash is excluded as it is not held by the non-bank public.

Calculate Quasi-Money (Near Money)

Quasi-Money = 650 + 350 = 1,000 billion Naira

Quasi-money consists of financial assets that are liquid but not directly usable as a medium of exchange, specifically savings deposits and time deposits.

Calculate Broad Money (

M_2

)

M2 = 1,400 + 1,000 = 2,400 billion Naira

Broad money supply combines M1 with quasi-money.

Match each cooperative principle on the left with its correct operational rule on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Democratic Control matches with 'Every member is entitled to exactly one vote regardless of the amount of share capital owned'; Patronage Dividend matches with 'Net surplus is distributed to members according to their volume of transactions with the society'; Open Membership matches with 'Membership is accessible to all eligible individuals without social, political, or religious discrimination'; Limited Interest on Capital matches with 'Returns on share capital are strictly capped to discourage profit speculation'.

The Rochdale principles establish specific operational rules for cooperatives: Democratic control guarantees one vote per person; patronage dividend allocates surplus by business volume; open membership prohibits discrimination; and limited interest on capital caps returns on invested money to prioritize service over profit.

Step-by-Step Solution

Identify the definition of Democratic Control in a cooperative society.

Democratic control operates on the rule of 'one man, one vote'.

Cooperative governance prioritizes equality of members over financial capital power.

Identify the principle of Patronage Dividend.

Patronage dividend distributes surplus based on trading participation.

Members earn returns according to how much they use the cooperative's services.

Identify the principle of Open and Voluntary Membership.

Membership is open without artificial barriers or discrimination.

This guarantees non-discriminatory access to economic cooperation.

Identify the principle of Limited Interest on Capital.

Interest rates on share contributions are capped.

This maintains the cooperative's primary objective as service provision rather than investor capital gain.

Question 13304Question →

When a mixed beam containing $\alpha$ -particles, $\beta$ -particles, and $\gamma$ -rays passes through a uniform electric field, the $\beta$ -particles undergo a significantly greater lateral deflection than the $\alpha$ -particles. Which of the following best explains this observation?

The charge-to-mass ratio of a

\beta

-particle is significantly greater than that of an

\alpha

-particle.

The magnitude of the electric force acting on a

\beta

-particle is greater than that acting on an

\alpha

-particle.

\beta

-particles travel at a much lower velocity than

\alpha

-particles, allowing the electric field more time to act on them.

\alpha

-particles possess no net electric charge and are therefore unaffected by the electric field.

Show answer & explanation

Answer: The charge-to-mass ratio of a $\beta$ -particle is significantly greater than that of an $\alpha$ -particle.

Answer

The charge-to-mass ratio of a

\beta

-particle is significantly greater than that of an

\alpha

-particle.

In a uniform electric field

E

, a charged particle experiences an acceleration given by

a = \frac{qE}{m}

. The degree of deflection is directly proportional to this acceleration, and hence to the charge-to-mass ratio (

\frac{q}{m}

). Even though an

\alpha

-particle carries twice the magnitude of charge of a

\beta

-particle (

2e

compared to

e

), an

\alpha

-particle is about

7300

times more massive than a

\beta

-particle. Consequently, the charge-to-mass ratio of the

\beta

-particle is thousands of times larger, causing it to undergo a significantly greater deflection in the field.

Step-by-Step Solution

Identify the relationship between electric field deflection and particle properties.

Deflection in a transverse electric field is proportional to acceleration

a = \frac{qE}{m}

, meaning deflection depends on the specific charge (charge-to-mass ratio,

\frac{q}{m}

Newton's second law (

F = ma

) combined with Electrostatic force (

F = qE

) gives

a = \frac{qE}{m}

Compare the charges and masses of

\alpha

-particles and

\beta

-particles.

For an

\alpha

-particle (

^{4}_{2}\text{He}^{2+}

q_{\alpha} = +2e

and

m_{\alpha} \approx 7300 m_e

. For a

\beta

-particle (

^{0}_{-1}\text{e}

q_{\beta} = -e

and

m_{\beta} = m_e

An alpha particle consists of 2 protons and 2 neutrons, making it much more massive than a single electron (beta particle).

Calculate and compare the charge-to-mass ratios.

\left|\frac{q_{\beta}}{m_{\beta}}\right| = \frac{e}{m_e}

, while

\left|\frac{q_{\alpha}}{m_{\alpha}}\right| \approx \frac{2e}{7300 m_e} = \frac{e}{3650 m_e}

. Thus,

\left|\frac{q_{\beta}}{m_{\beta}}\right| \approx 3650 \times \left|\frac{q_{\alpha}}{m_{\alpha}}\right|

The vastly smaller mass of the beta particle dominates the ratio, resulting in a much larger charge-to-mass ratio and therefore a greater deflection.

Read the poetic extract below:

"Slowly, the golden moon moves through the cool blue gloom of noon."

Which sound device is predominantly used in this extract, and what auditory quality does it contribute to the lines?

Assonance, creating a smooth and euphonious rhythm through the repetition of the internal long /uː/ vowel sound

Alliteration, producing a harsh, cacophonous quality through the repetition of initial consonant sounds

Sibilance, creating a tense, whispering atmosphere through prominent initial 's' sounds

Onomatopoeia, imitating the literal sounds of night animals to heighten dramatic action

Show answer & explanation

Answer: Assonance, creating a smooth and euphonious rhythm through the repetition of the internal long /uː/ vowel sound

Answer

Assonance, creating a smooth and euphonious rhythm through the repetition of the internal long /uː/ vowel sound.

The extract predominantly features the repetition of the internal vowel sound /uː/ ('moon', 'through', 'cool', 'blue', 'gloom', 'noon'), which is assonance. This elongated vowel pattern gives the lines a melodious, smooth, and harmonious sound effect, characteristic of euphony.

Step-by-Step Solution

Examine the phonetic structure of the poetic line.

Identify the prominent repetition of the internal vowel sound /uː/ in words such as 'moon', 'through', 'cool', 'blue', 'gloom', and 'noon'.

Identifying repeated phonetic elements determines the primary sound device present.

Match the identified sound pattern to its literary definition.

The repetition of similar vowel sounds within nearby words is defined as assonance.

Assonance relies specifically on internal vowel sound agreement rather than initial consonant matching.

Analyze the acoustic effect of the dominant sound pattern.

The elongated vowel sounds produce a soft, pleasing, and harmonious musical effect, known as euphony.

Euphony refers to agreeable, harmonious combinations of sounds that enhance peaceful poetic imagery.

Question 13307Question →

A logistics firm's delivery van valued at ₦12,000,000 was damaged in a road collision caused by a third party's negligence, resulting in ₦4,000,000 worth of structural damage. The insurance company fully indemnified the logistics firm for the ₦4,000,000 loss. When the logistics firm subsequently attempted to sue the negligent third party to recover another ₦4,000,000 for the exact same damage, the court dismissed the firm's suit. Which basic principle of insurance legally empowers the insurer to step into the shoes of the insured and assume their rights of recovery against negligent third parties?

Subrogation

Contribution

Utmost Good Faith

Insurable Interest

Show answer & explanation

Answer: Subrogation

Answer

Subrogation is the principle of insurance that legally transfers the rights of recovery against a negligent third party from the insured to the insurer after full compensation has been paid.

Subrogation is a direct corollary of the principle of indemnity. Once an insurer compensates the insured for a loss, the insurer assumes all legal rights and remedies that the insured possessed against the party responsible for the damage. This prevents double recovery by the insured while ensuring the negligent third party remains accountable.

Step-by-Step Solution

Analyze the legal scenario and the relationship between the three parties (insured, insurer, third-party tortfeasor).

The insured suffered a loss of ₦4,000,000 caused by a negligent third party and received full financial restitution (indemnity) from their insurer.

Establishing that full indemnity has taken place is essential before subrogation rights can take effect.

Evaluate why the insured cannot collect another ₦4,000,000 from the negligent driver.

Allowing double recovery would violate the fundamental doctrine of indemnity by enabling the insured to make a profit from an insurance claim.

Insurance contracts of indemnity aim strictly to restore the policyholder to their pre-loss financial position.

Identify the specific legal mechanism that transfers legal recourse to the insurer.

Subrogation allows the insurer to step into the insured's legal standing to sue the negligent party and recover the paid out claim.

Subrogation acts as a direct corollary of indemnity to ensure tortfeasors remain held accountable without rewarding policyholders with double compensation.

Match each Sale of Goods Act term on the left with its correct legal definition or legal effect on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Condition matches fundamental term allowing contract repudiation; Warranty matches collateral term giving claim to damages only; Quiet Possession matches implied warranty of undisturbed enjoyment; Fitness for Purpose matches implied condition of suitability for communicated use.

Each concept correctly aligns with its legal definition under the Sale of Goods Act: Condition corresponds to contract repudiation rights, Warranty corresponds to damages claims only, Quiet Possession corresponds to undisturbed buyer enjoyment, and Fitness for Purpose corresponds to suitability for a specified purpose.

Step-by-Step Solution

Distinguish between major and minor contractual terms under commercial law.

Conditions are vital terms that go to the root of the contract, whereas warranties are subsidiary terms.

This legal distinction dictates whether a buyer has the right to reject goods or merely seek monetary compensation.

Categorize specific statutory provisions into implied conditions or implied warranties.

Quiet possession is classified as an implied warranty, while fitness for purpose is classified as an implied condition.

The Sale of Goods Act explicitly defines freedom from third-party claims as a warranty and specific buyer suitability reliance as a condition.

\text{N}1,600,000

\text{N}1,600,000

(calculated without liquidity reserve)

\text{N}100,000

Show answer & explanation

Answer: $\text{N}1,200,000$

Answer

The maximum amount of derivative deposits created is

\text{N}1,200,000

The effective reserve ratio is

25\%

(

0.25

), yielding a credit expansion multiplier of

4

. The overall deposit liabilities created total

\text{N}1,600,000

. Subtracting the initial cash deposit of

\text{N}400,000

yields

\text{N}1,200,000

in derivative deposits.

Step-by-Step Solution

Calculate the total effective reserve ratio.

Total Reserve Ratio (

r

) = Statutory Cash Reserve Ratio (

20\%

) + Voluntary Liquidity Reserve (

5\%) = 25\% = 0.25

Both statutory reserves and voluntary liquidity cushions restrict the proportion of deposits available for lending.

Determine the credit expansion multiplier.

Credit Multiplier (

K

) =

\frac{1}{r} = \frac{1}{0.25} = 4

The deposit multiplier is the reciprocal of the total reserve ratio.

Calculate total deposit expansion in the banking system.

Total Deposit Expansion = Primary Deposit

\times K = \text{N}400,000 \times 4 = \text{N}1,600,000

Multiplying the initial primary deposit by the multiplier gives the total capacity of credit and deposit generation.

Isolate the derivative deposits generated.

Derivative Deposits = Total Expansion - Primary Deposit =

\text{N}1,600,000 - \text{N}400,000 = \text{N}1,200,000

Derivative deposits represent secondary credit created by commercial banks beyond the original cash injection.

Question 13311Question →

Two point masses, each of mass $125\text{ kg}$ , are fixed at positions $(-3.0\text{ m}, 0)$ and $(3.0\text{ m}, 0)$ in the $xy$ -plane. What is the magnitude of the net gravitational field strength at a point $P$ located at $(0, 4.0\text{ m})$ , in terms of the universal gravitational constant $G$ ?

8.0G\text{ N/kg}

10.0G\text{ N/kg}

6.0G\text{ N/kg}

4.0G\text{ N/kg}

Show answer & explanation

Answer: $8.0G\text{ N/kg}$

Answer

The magnitude of the net gravitational field strength at point

P

8.0G\text{ N/kg}

The distance from each mass to the target point is 5.0 m, yielding an individual field magnitude of 5.0G N/kg. Resolving vectors shows that horizontal components cancel out while vertical components add to give 2 × (5.0G × 4/5) = 8.0G N/kg.

Step-by-Step Solution

Calculate the distance

r

from each mass to point

P(0, 4.0\text{ m})

r = \sqrt{(-3.0 - 0)^2 + (0 - 4.0)^2} = \sqrt{9 + 16} = 5.0\text{ m}

The distance formula in two dimensions gives the hypotenuse of the right triangle formed by the coordinates.

Determine the magnitude of the gravitational field

E

created by each individual mass at point

P

E = \frac{G M}{r^2} = \frac{G \times 125}{5.0^2} = \frac{125G}{25} = 5.0G\text{ N/kg}

Newton's law of universal gravitation defines field strength as

E = \frac{GM}{r^2}

Resolve the field vectors into horizontal and vertical components.

By symmetry, the horizontal components

E_x = E \sin\theta

are equal in magnitude and opposite in direction, so

E_{x,\text{net}} = 0

. The vertical components

E_y = E \cos\theta

point downwards towards the origin.

Gravitational field is a vector quantity, so opposite components cancel while aligned components add together.

Calculate the total vertical component of the net gravitational field.

\cos\theta = \frac{4.0}{5.0} = 0.8

. Thus,

E_{\text{net}} = 2 \times E_y = 2 \times (5.0G \times 0.8) = 8.0G\text{ N/kg}

Summing the vertical contributions from both identical masses gives the net magnitude.

Show answer & explanation

Answer

The correct pairings match each operational practice to its corresponding Rochdale principle: voting equality corresponds to Democratic Control, surplus sharing by transaction volume corresponds to Patronage Refund, capping interest on share capital corresponds to Limited Return on Capital, and non-discriminatory admission corresponds to Voluntary and Open Membership.

Each cooperative operational practice directly represents a core Rochdale principle: equal voting power illustrates Democratic Control, returning profits based on usage represents Patronage Refund, restricting interest rates on equity represents Limited Return on Capital, and open enrollment reflects Voluntary and Open Membership.

Step-by-Step Solution

Analyze voting rights in cooperative governance.

Allocating one vote per member regardless of shareholding exemplifies Democratic Control.

Cooperatives prioritize democratic membership over capital ownership.

Determine how economic surplus is shared among members.

Distributing surplus according to purchase or transaction volume matches Patronage Refund.

Surplus distribution rewards member usage rather than financial investment.

Evaluate the restriction on dividend/interest paid on share capital.

Capping interest on capital contributions matches Limited Return on Capital.

This prevents speculation and ensures service to members remains the primary goal.

Examine member entry and exit rules.

32\text{ days}

, a sample with an

8\text{-day}

half-life undergoes

4

complete half-lives (

32 / 8 = 4

). The remaining activity is

160 \times (1/2)^4 = 10\text{ kBq}

. The activity that has decayed is the initial activity minus the remaining activity:

160\text{ kBq} - 10\text{ kBq} = 150\text{ kBq}

Step-by-Step Solution

Calculate the total number of half-lives (

n

) that have elapsed.

n = \frac{\text{Total time } (t)}{\text{Half-life } (T_{1/2})} = \frac{32\text{ days}}{8\text{ days}} = 4

Determining how many half-life periods fit into the total elapsed time.

Calculate the remaining activity (

A

) of the sample.

A = A_0 \left(\frac{1}{2}\right)^n = 160\text{ kBq} \times \left(\frac{1}{2}\right)^4 = 160 \times \frac{1}{16} = 10\text{ kBq}

Applying the radioactive decay law to find the undecayed fraction.

Calculate the activity corresponding to the decayed amount.

A_{\text{decayed}} = A_0 - A = 160\text{ kBq} - 10\text{ kBq} = 150\text{ kBq}

Subtracting the remaining activity from the initial activity gives the decayed activity.

Answer

Bonded Warehouse matches with storing imported dutiable goods under customs control; Public Warehouse matches with offering rental storage space to traders for a fee; Private Warehouse matches with exclusive storage facilities owned by a business for its own inventory; State Warehouse matches with storing seized contraband and unclaimed goods under government oversight.

Each warehouse classification serves a distinct legal and operational function: Bonded warehouses allow importers to defer tariff payment while goods remain under bond; Public warehouses offer commercial storage on hire to any trader; Private warehouses accommodate an individual firm's proprietary inventory; and State warehouses store confiscated or unclaimed items in government custody.

Step-by-Step Solution

Analyze the operational features of Bonded and State warehouses

Bonded warehouses deal with un-cleared imported goods awaiting duty payment under customs supervision, while State warehouses hold seized contraband and unclaimed goods under government control.

Regulatory ownership and customs status differentiate these two government-regulated facilities.

Analyze the ownership and accessibility features of Public and Private warehouses

Private warehouses are restricted to exclusive use by their owner firm, whereas Public warehouses hire out space for rental fees to any trader in need of storage.

Commercial availability and ownership determine whether a warehouse is private or public.

Pair each warehouse type with its accurate descriptor

Bonded Warehouse pairs with duty-deferred storage under customs bond; Public Warehouse pairs with rental storage for general merchants; Private Warehouse pairs with exclusive company-owned storage; State Warehouse pairs with government custody of impounded/unclaimed stock.

Tayo remains personally liable to prospective buyers for breach of an implied warranty of authority.

The agency is indefinitely suspended and automatically revives whenever Ade acquires a replacement vessel.

Show answer & explanation

Answer: The agency is automatically terminated by operation of law due to the destruction of the subject matter.

Answer

The agency is automatically terminated by operation of law due to the destruction of the subject matter.

An agency relationship is automatically discharged by operation of law when performance becomes impossible due to the destruction of the subject matter. Because the specific cargo vessel was destroyed, the foundation of Tayo's authority ceased to exist, bringing the agency to an immediate legal end.

Step-by-Step Solution

Identify the key legal event in the principal-agent scenario.

The specific vessel that forms the core subject matter of the agency was completely destroyed before performance.

Determining how the contract's subject matter was affected dictates the legal rule for agency termination.

Apply the legal rules governing termination of agency under commercial law.

Destruction of the subject matter constitutes frustration and terminates the agency automatically by operation of law.

Without the subject matter, performance becomes legally impossible, rendering further agency authority void without requiring express revocation.

To transition from an Import Substitution Industrialization (ISI) strategy toward an Export Promotion Strategy (EPS), a government seeks to make its manufacturing sector internationally competitive. Which policy measure directly supports this transition?

Imposing high protective tariffs and restrictive import quotas on foreign consumer goods

Granting export subsidies and tax incentives to domestic manufacturing firms targeting foreign markets

Fixing maximum price ceilings on locally manufactured goods sold in domestic markets

Nationalizing foreign-owned manufacturing enterprises to restrict capital flight

Show answer & explanation

Answer: Granting export subsidies and tax incentives to domestic manufacturing firms targeting foreign markets

Answer

Granting export subsidies and tax incentives to domestic manufacturing firms targeting foreign markets

Export Promotion Strategies aim to expand domestic industrial output by producing goods for external markets. Providing export subsidies, tax holidays, and financial incentives reduces export production costs, making domestic manufactured goods price-competitive internationally.

Step-by-Step Solution

Identify the core goal of an Export Promotion Strategy (EPS).

EPS focuses on encouraging industrial growth by expanding manufacturing exports into foreign markets.

Unlike Import Substitution, which looks inward to replace imports, Export Promotion looks outward to achieve economies of scale through international trade.

Evaluate the policy mechanisms required to achieve foreign market penetration.

Domestic firms must lower export prices and improve quality to compete with established global manufacturers.

Direct financial incentives such as export subsidies, duty drawbacks, and tax breaks lower unit costs for exporters.

Distinguish Export Promotion tools from Import Substitution tools.

Tariffs and quotas restrict imports (ISI), whereas subsidies and credit facilities boost exports (EPS).

Conflating protective trade barriers with outward-oriented promotion measures is a common error in industrial policy analysis.

Read the excerpt below from Agostino Neto's prescribed African poem, *The Grieved of Africa*:

"In the tears of Africa
In the laughter of Africa
In the sweat of Africa
In the blood of Africa"

What literary effect is primarily achieved by the repetition of the line-initial phrase in this excerpt?

It builds anaphoric emphasis to underscore the pervasive and multifaceted historical experience of African endurance.

It creates a playful, romantic mood that diminishes the poem's focus on anti-colonial resistance.

It highlights a sudden shift from agrarian rural life to modern industrial urbanization.

It enforces a strict iambic pentameter rhyme scheme characteristic of an English sonnet.

Show answer & explanation

Answer: It builds anaphoric emphasis to underscore the pervasive and multifaceted historical experience of African endurance.

Answer

The structural repetition of the phrase at the beginning of successive lines functions as anaphora, emphasizing the ubiquitous nature of human suffering and resilience across the continent's history.

The correct response accurately identifies the use of anaphora (the repetition of 'In the...' at the start of successive lines) and correctly connects this rhetorical device to its function: accumulating emotional weight to illustrate how struggle and resilience permeate all facets of African life.

Step-by-Step Solution

Identify the structural device present in the excerpt.

The phrase 'In the...' repeats at the beginning of four consecutive lines, which defines the poetic device anaphora.

Recognizing syntactic repetition is essential for analyzing poetic form.

Analyze the thematic connection between the device and the words 'tears', 'laughter', 'sweat', and 'blood'.

The terms cover emotional pain, joy, hard physical work, and martyrdom, capturing the total human condition under oppression.

Anaphora serves to accumulate intensity and highlight the total scope of the subject matter.

Evaluate the choices to select the statement that correctly pairs the device function with the thematic context of Neto's poem.

The statement identifying anaphoric emphasis on the pervasive historical experience of African endurance is accurate.

Agostino Neto's poetry focuses on anti-colonial consciousness, collective identity, and resilience.
