Question 5141Question

A political system achieves voluntary compliance and allegiance primarily when citizens accept its fundamental right to govern. Which of the following mechanisms is most vital for maintaining this political legitimacy in a democratic state?

Show answer & explanation

Answer: Upholding the rule of law, protecting basic rights, and conducting regular free elections

Answer

Upholding the rule of law, protecting basic rights, and conducting regular free elections
Political legitimacy is sustained in democratic governance through legal-rational processes, good governance, protection of fundamental human rights, and regular, credible elections that grant the government popular consent.

Step-by-Step Solution

1
Define political legitimacy
Legitimacy refers to the lawful right to govern and the popular recognition/acceptance of that authority by the citizens.
Understanding the definition helps distinguish consent-based governance from coercive control.
2
Identify key determinants and maintenance factors for democratic legitimacy
Democratic legitimacy relies on constitutional governance, accountability, protection of human rights, and periodic transparent elections.
Citizens voluntarily support a state when government operations align with legal-rational rules and respect democratic norms.
3
Evaluate options against maintenance mechanisms
Upholding the rule of law and conducting free elections directly sustains citizen confidence and constitutional right to rule.
Alternative options rely on state coercion or autocratic consolidation, which erode legitimacy rather than maintain it.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of stages in passing a bill into law is First Reading, Second Reading, Committee Stage, Third Reading, and Presidential Assent.
The standard legislative process follows a set procedural order to ensure thorough deliberation: formal introduction (First Reading), general principle debate (Second Reading), detailed clause scrutiny by specialists (Committee Stage), final vote by the whole house (Third Reading), and executive signature (Presidential Assent).

Step-by-Step Solution

1
Identify the formal introduction step
First Reading is the first stage.
A bill must first be formally introduced to the house by reading its short title before any debate can occur.
2
Identify the initial debate stage
Second Reading follows First Reading.
Once introduced, lawmakers debate the general principles and broad merits of the bill.
3
Identify the detailed examination stage
Committee Stage follows Second Reading.
After the house approves the general principles in the second reading, the bill is committed to a legislative committee for clause-by-clause scrutiny.
4
Identify the final voting stage in the chamber
Third Reading follows Committee Stage (and Report Stage).
The house receives the committee's report, conducts a final review of the clean bill, and votes on its passage.
5
Identify the final enactment step
Presidential Assent is the final stage.
A bill passed by the legislature requires executive signature to gain force of law as an Act.

Question 5143Question

A commercial banking enterprise based in Lagos expands its long-run scale of operations by acquiring two smaller financial institutions and centralizing its administrative management and information technology infrastructure. Following this expansion, the bank observes a sustained reduction in its long-run average cost per customer transaction serviced. Which of the following best describes the cost advantage experienced by the firm?

Show answer & explanation

Answer: Internal economies of scale

Answer

The cost advantage experienced by the bank is classified as internal economies of scale.
When a firm expands its individual operations and reorganizes its internal structure—such as centralizing IT services and managerial operations—it achieves managerial and technical efficiency. This lowers its average cost per unit of output in the long run, which is the precise definition of internal economies of scale.

Step-by-Step Solution

1
Identify the nature of the firm's growth
The firm is expanding its own individual scale of operation long-term by acquiring other institutions and restructuring internal IT and management systems.
Cost reductions stemming from actions taken within the boundaries of a single firm represent internal developments rather than industry-wide factors.
2
Analyze the impact on unit production cost
The bank experiences a decline in long-run average cost per unit of service (customer transaction).
A fall in long-run average costs as scale increases defines economies of scale.
3
Distinguish between internal and external factors as well as short-run vs long-run dynamics
Because the efficiency gains (managerial and technical specialization) occur within the expanding firm across all inputs in the long run, this constitutes internal economies of scale.
Efficiency gains unique to the expanding business entity represent internal economies of scale.

Question 5145Question

A consumer in a local market is willing to pay a maximum of ₦1,200 for a pair of sandals, but purchases them at the prevailing market price of ₦800. What is the value of the consumer surplus derived from this purchase?

Show answer & explanation

Answer: ₦400

Answer

₦400
The consumer surplus is ₦400 because it represents the difference between the maximum amount the consumer was prepared to pay (₦1,200) and the price actually paid in the market (₦800).

Step-by-Step Solution

1
Identify the consumer's maximum willingness to pay and the actual price paid in the market.
Maximum Willingness to Pay = ₦1,200; Market Price Paid = ₦800.
Consumer surplus measures the economic benefit received by paying less than maximum willingness.
2
Apply the consumer surplus formula: Consumer Surplus = Maximum Willingness to Pay - Actual Price Paid.
Consumer Surplus = ₦1,200 - ₦800 = ₦400.
Subtracting actual expenditure from total monetary valuation yields the net benefit.

Key Concept

Consumer surplus is the difference between the maximum amount a consumer is willing to pay for a commodity and the actual amount paid.
Question 5146Question

In a presidential system of government, which constitutional mechanism enables the legislature to override an executive veto and enact a bill into law without presidential assent?

Show answer & explanation

Answer: Re-passing the bill by a two-thirds majority vote in the legislature

Answer

Re-passing the bill by a two-thirds majority vote in the legislature
Re-passing the bill by a two-thirds majority vote in the legislature is the established constitutional procedure in a presidential democracy to override an executive veto and convert a bill into law without presidential assent.

Step-by-Step Solution

1
Identify the legislative mechanism designated to resolve executive withholding of assent.
The legislature uses its checks-and-balances power to execute a veto override.
Under the principle of separation of powers, the executive cannot permanently block legislative intent if a strong legislative consensus exists.
2
Determine the required voting threshold needed to pass the vetoed bill into law.
A two-thirds supermajority vote of the legislative assembly is mandatory.
Constitutional provisions mandate a higher threshold than a simple majority to ensure widespread legislative agreement before bypassing presidential assent.

Question 5147Question

Country X recorded a 7%7\% annual increase in its real Gross Domestic Product (GDP) over a ten-year period; however, its poverty rate, unemployment rate, and illiteracy levels remained entirely unimproved. How would economists best classify this nation's economic experience?

Show answer & explanation

Answer: Economic growth without economic development

Answer

Economic growth without economic development
The correct answer highlights economic growth occurring in isolation from economic development. Economic growth is a single-dimensional quantitative expansion in real GDP. In contrast, economic development is a multi-dimensional qualitative process that encompasses improvements in standard of living, poverty reduction, lower unemployment, and higher literacy. A persistent rise in national income alongside static welfare indicators exemplifies growth without development.

Step-by-Step Solution

1
Analyze the nature of the 7%7\% annual rise in real GDP
Real GDP expansion represents a purely quantitative increase in national physical output.
Economic growth is defined specifically by measurable increases in aggregate output or real income per capita over time.
2
Evaluate the state of social indicators (poverty, unemployment, illiteracy)
Social and living standard indicators remained unchanged.
Economic development requires multidimensional qualitative changes, such as reduced poverty, improved literacy, better healthcare, and institutional improvements.
3
Synthesize the findings to distinguish between growth and development
The country experienced quantitative growth in national output without achieving qualitative development in living standards.
Growth can occur independently of development if the benefits of increased GDP fail to improve general social welfare.

Question 5148Question

A constitutional document classified as written is inherently rigid, as any written constitution automatically requires a complex or special legislative procedure to be amended.

Show answer & explanation

Answer: False

Answer

False. A written constitution refers to its formal codification in a single document, whereas rigidity concerns the legal procedure required for amendment. Codification does not automatically make a constitution rigid.
The statement is false because 'written' describes a constitution's physical codification in a single document, while 'rigid' describes a strict amendment process requiring special procedures. The two concepts represent separate classification criteria.

Step-by-Step Solution

1
Distinguish between constitutional classification criteria.
Classification by form separates constitutions into written (codified) and unwritten (uncodified), while classification by amendment method separates them into rigid and flexible.
Different classification schemes measure distinct structural characteristics of a constitution.
2
Evaluate the relationship between written form and constitutional rigidity.
While written constitutions are frequently rigid, the format itself does not mandate a complex amendment process. A written constitution can be altered by a simple parliamentary majority if its text permits.
Rigidity depends strictly on specific constitutional clauses governing amendments, not merely on whether the text is codified.

Question 5151Question

In Gabriel Almond and Sidney Verba's typology of political culture, a subject political culture is characterized by citizens who possess high cognitive awareness of governmental outputs and administrative authority, but demonstrate passive orientations with minimal participation in political input processes.

Show answer & explanation

Answer: True

Answer

The statement is True. In a subject political culture, individuals are aware of political authority and decision outputs but play a passive role regarding political input and participation.
The statement accurately reflects Gabriel Almond and Sidney Verba's classic comparative political analysis in 'The Civic Culture'. A subject political culture is defined by citizens who recognize governmental power, administrative institutions, and policy outputs, but maintain an inactive, compliant stance toward input processes such as political activism and legislative participation.

Step-by-Step Solution

1
Analyze the core definition of Almond and Verba's subject political culture typology.
Subject political culture differentiates between system outputs (laws, administration, decisions) and system inputs (voting, lobbying, policy formulation).
Almond and Verba categorize political cultures based on cognitive, affective, and evaluative orientations toward political inputs and outputs.
2
Evaluate citizen orientation toward political outputs versus inputs in a subject culture.
Citizens show high awareness of governmental authority and outputs, but low involvement and passive orientation toward input structures.
Unlike participant culture where citizens engage in both inputs and outputs, subject citizens view themselves as affected by laws rather than as actors who shape them.
3
Differentiate subject culture from parochial and participant cultures.
Parochial culture lacks awareness of both inputs and outputs; participant culture actively engages with both; subject culture uniquely balances high output awareness with minimal input participation.
This structural distinction confirms that the given statement accurately defines a subject political culture.

Question 5152Question

During a national economic reform program, a state government enforces prompt payment of income taxes under penalty of prosecution, while encouraging citizens to voluntarily participate in neighborhood watch programs and voter registration drives. Which of the following statements correctly distinguishes the legal nature of these civic responsibilities?

Show answer & explanation

Answer: Tax payment is a compulsory legal obligation enforceable by legal sanctions, whereas participating in neighborhood watch and voter registration are moral and civic duties.

Answer

Tax payment is a compulsory legal obligation enforceable by legal sanctions, whereas participating in neighborhood watch and voter registration are moral and civic duties.
The correct option accurately distinguishes between legal obligations and civic duties. Paying taxes is a statutory requirement created by legislation, making failure to pay a punishable offense. Conversely, joining neighborhood watches and registering to vote are voluntary civic activities aimed at fostering community security and democratic engagement.

Step-by-Step Solution

1
Analyze the nature of tax payment under statutory law.
Identify that tax payment is mandatory by law and non-compliance attracts prosecution, fines, or imprisonment, defining it strictly as a legal obligation.
Legal obligations are compulsory duties backed by state coercive power and legal sanctions.
2
Analyze the nature of neighborhood watch participation and voter registration drives.
Identify that these activities are encouraged for community welfare and democratic participation but are not legally punishable if ignored, defining them as civic or moral duties.
Civic duties rely on civic consciousness, responsibility, and patriotism rather than criminal prosecution.
3
Compare the analyzed definitions against the options provided.
Select the statement that correctly categorizes tax payment as a legal obligation and community/voter participation as civic/moral duties.
Accurate distinction between rights, duties, and obligations is essential in constitutional government.

Question 5153Question

While both authoritarian and totalitarian regimes restrict political competition and democratic freedoms, which of the following features fundamentally distinguishes a totalitarian system from an authoritarian one?

Show answer & explanation

Answer: The enforcement of an all-encompassing official ideology that seeks total penetration of private life and demands active mass mobilization

Answer

The fundamental distinction lies in totalitarianism's enforcement of an all-encompassing official ideology that penetrates both public and private life while demanding active mass mobilization.
The correct answer identifies that totalitarianism demands complete ideological adherence and total intrusion into private life along with mass mobilization, whereas authoritarianism focuses primarily on monopolizing political power while permitting relative autonomy in non-political private and social domains.

Step-by-Step Solution

1
Examine the scope of control in authoritarian governance.
Authoritarian regimes seek a monopoly on political power, suppressing political pluralism while typically leaving non-political social institutions, religious practices, and private spheres largely untouched as long as they do not threaten the regime.
Establishing the functional boundary of authoritarian control provides the necessary baseline for comparison.
2
Examine the scope of control in totalitarian governance.
Totalitarian regimes aim to reshape society completely under an official ideology, erasing the boundary between the state and private life while requiring enthusiastic public participation and compliance.
Highlighting total ideological mobilization identifies the core theoretical differentiator.
3
Match findings to the correct option.
The statement describing the total penetration of private life through an all-encompassing official ideology and mass mobilization accurately captures this essential distinction.
Differentiates totalitarianism from authoritarian features like mere political coercion or executive power concentration.

Question 5154Question

Apex Plc has an issued share capital of 800,000800,000 ordinary shares of 0.50\text{₦}0.50 each. The company announces a bonus issue of 11 new ordinary share for every 44 shares held. Following the completion of the bonus issue, the company makes a rights issue of 11 new ordinary share for every 55 existing shares held at an issue price of 1.20\text{₦}1.20 per share. What is the total value of the company's issued ordinary share capital in Naira (\text{₦}) after both the bonus issue and rights issue are fully executed?

Show answer & explanation

Answer: 600000

Answer

The total value of the company's issued ordinary share capital after both the bonus and rights issues is ₦600,000.
To find the post-issue share capital, calculate the nominal value added by each transaction. Initial share capital is 800,000 shares × ₦0.50 = ₦400,000. A 1-for-4 bonus issue adds 200,000 shares (800,000 / 4), increasing nominal share capital by ₦100,000 (200,000 × ₦0.50) and bringing total shares to 1,000,000. A 1-for-5 rights issue on these 1,000,000 shares adds 200,000 shares (1,000,000 / 5). Only the nominal value of ₦0.50 per rights share is added to Share Capital (200,000 × ₦0.50 = ₦100,000), while the ₦0.70 excess per share is credited to Share Premium. Combining ₦400,000 + ₦100,000 + ₦100,000 yields the final issued ordinary share capital of ₦600,000.

Step-by-Step Solution

1
Calculate the initial issued ordinary share capital
800,000 \text{ shares} \times \text{₦}0.50 = \text{₦}400,000
Issued share capital is recorded strictly at the nominal (par) value per share.
2
Determine the number of bonus shares issued and nominal value capitalized
\text{Bonus shares} = \frac{800,000}{4} = 200,000 \text{ shares}; \quad \text{Nominal value} = 200,000 \times \text{₦}0.50 = \text{₦}100,000
A 1-for-4 bonus issue issues 1 new share for every 4 existing shares held, using reserves to fund the nominal value without receiving cash.
3
Determine the total number of issued shares prior to the rights issue
800,000 + 200,000 = 1,000,000 \text{ shares}
The rights issue occurs after the bonus issue, so the ratio applies to all post-bonus shares.
4
Determine the number of rights shares issued and nominal value added to share capital
\text{Rights shares} = \frac{1,000,000}{5} = 200,000 \text{ shares}; \quad \text{Nominal capital added} = 200,000 \times \text{₦}0.50 = \text{₦}100,000
Only the nominal value (₦0.50 per share) increases the Issued Share Capital account. The excess issue price (₦1.20 - ₦0.50 = ₦0.70 per share) is credited to the Share Premium account.
5
Calculate the total final issued ordinary share capital
\text{₦}400,000 + \text{₦}100,000 + \text{₦}100,000 = \text{₦}600,000
Summing the initial capital with the nominal values added by the bonus and rights issues gives the final Share Capital balance.

Question 5155Question

Which of the following evolutionary trends in structural adaptation enabled pteridophytes to achieve larger body sizes and greater terrestrial independence than bryophytes?

Show answer & explanation

Answer: The development of lignified vascular tissues within a dominant sporophyte generation

Answer

The development of lignified vascular tissues within a dominant sporophyte generation.
The development of lignified vascular tissues (xylem and phloem) in the dominant sporophyte generation is the key evolutionary innovation that allowed pteridophytes to transport water and nutrients efficiently over greater distances and maintain erect growth on land compared to non-vascular bryophytes.

Step-by-Step Solution

1
Identify the structural limitations of bryophytes in terrestrial environments.
Bryophytes lack true vascular tissue (xylem and phloem) and rely on diffusion, limiting their height and restricting them to damp habitats.
Understanding the baseline evolutionary state helps pinpoint the innovations that occurred in subsequent plant groups.
2
Analyze the major evolutionary advancement introduced by pteridophytes.
Pteridophytes developed lignified xylem and phloem in their sporophyte phase, enabling internal transport of water and structural support.
Vascularization allowed plants to grow taller and inhabit drier terrestrial niches.
3
Evaluate the change in generational dominance.
The sporophyte generation became the dominant, independent phase of the life cycle, while the gametophyte became reduced.
A dominant sporophyte with vascular tissue represents the key evolutionary trend from bryophytes to pteridophytes.

Key Concept

Evolutionary transition from non-vascular, gametophyte-dominant plants (bryophytes) to vascular, sporophyte-dominant plants (pteridophytes).

Question 5156Question

During a period of severe economic downturn, a low-income household observes that when the price of cassava flour—their primary staple food—rises, their monthly consumption of cassava flour actually increases because they can no longer afford meat or rice. Which economic concept accounts for this exception to the standard law of demand?

Show answer & explanation

Answer: Giffen good behavior, where the negative income effect of a price rise in a staple good overrides the substitution effect

Answer

Giffen good behavior explains this phenomenon because the income effect of a price rise in an essential inferior staple outweighs the substitution effect, leading to an upward-sloping demand relationship.
The scenario describes a classic Giffen good situation. For a low-income consumer, cassava flour is a staple inferior good. When its price increases, the consumer's real income declines sharply. Because they can no longer afford premium foods like meat or rice, they substitute away from those expensive items toward buying more cassava flour to survive, making the income effect override the substitution effect.

Step-by-Step Solution

1
Identify the relationship between price and quantity demanded described in the scenario
As the price of cassava flour rises, the quantity demanded increases, demonstrating an upward-sloping demand curve.
This scenario presents an inverse of the normal law of demand, which states that price and quantity demanded are inversely related.
2
Analyze the economic nature of the product and consumer background
Cassava flour is a basic staple food consumed by low-income households who spend a large portion of their budget on it.
When the price of such a staple rises, the household's real purchasing power falls significantly (negative income effect), forcing them to cut back on expensive foods (like meat and rice) and buy more of the cheap staple.
3
Distinguish between types of demand exceptions
This phenomenon is classified as a Giffen good, whereas luxury/prestige goods fall under the Veblen effect.
Giffen goods apply to inferior staple foods for low-income consumers, satisfying the specific conditions described.

Question 5157Question

In a barter economy, the difficulty of making deferred payments arises primarily because goods used in exchange fluctuate in value and are prone to perishability over time.

Show answer & explanation

Answer: True

Answer

True. In a barter system, commodities lack value stability and long-term durability, making fair deferred (future) payment contracts unreliable.
The statement is true because physical commodities traded under a barter system lack long-term stability in value and durability, hindering fair credit agreements and future debt settlements.

Step-by-Step Solution

1
Identify the specific limitation of the barter system being evaluated in the statement.
The statement highlights the problem of making deferred (future/credit) payments in a moneyless system.
Deferred payments require an agreed-upon standard that holds consistent value over time.
2
Analyze the physical and economic properties of commodities traded under barter.
Commodities such as agricultural goods or livestock suffer from spoilage, quality degradation, and fluctuating supply conditions.
These physical and market changes alter the commodity's real value over time, creating risk for creditors or debtors.
3
Conclude the truth value of the stem based on economic principles.
The statement is true because the lack of durability and value stability directly creates the deferred payment drawback in barter.
Money resolves this exact flaw by functioning as a durable and standardized unit of deferred payment.

Answer

Rhombic sulfur matches the stable octahedral crystalline allotrope below 95.6C95.6^\circ\text{C}; Hydrogen sulfide matches the poisonous gas with a rotten-egg smell that turns lead(II) ethanoate paper black; Sulfur(IV) oxide matches the gaseous reducing agent that turns acidified potassium dichromate(VI) solution from orange to green; Plastic sulfur matches the amorphous, rubber-like allotrope formed by rapidly cooling boiling sulfur in cold water.
Rhombic sulfur is the stable octahedral crystalline allotrope at room temperature (<95.6C< 95.6^\circ\text{C}). Hydrogen sulfide is a toxic gas characterized by a rotten-egg odor and the ability to turn moist lead(II) ethanoate paper black due to PbSPbS formation. Sulfur(IV) oxide is a gaseous reducing agent that changes orange acidified potassium dichromate(VI) to green chromium(III). Plastic sulfur is an amorphous, elastic allotrope made by quenching boiling sulfur in cold water.

Step-by-Step Solution

1
Identify the physical properties and structures of sulfur allotropes.
Rhombic sulfur (α\alpha-sulfur) consists of octahedral crystals stable below 95.6C95.6^\circ\text{C}, while plastic sulfur is formed by pouring boiling sulfur into cold water, producing an amorphous, rubbery solid.
Allotropes exhibit different structural arrangements and stability ranges based on temperature and cooling rate.
2
Analyze qualitative test reactions for hydrogen sulfide (H2SH_2S) and sulfur(IV) oxide (SO2SO_2).
Hydrogen sulfide gas has a distinctive rotten-egg odor and reacts with lead(II) ethanoate to precipitate black lead(II) sulfide (PbSPbS). Sulfur(IV) oxide is a reducing agent that reduces orange Cr2O72Cr_2O_7^{2-} to green Cr3+Cr^{3+}.
Each gas has unique chemical properties and reagent tests suitable for laboratory identification.

The historical expansion of suffrage progressed sequentially from absolute rule with no popular voting rights, to restricted franchise based on wealth and tax qualifications, followed by universal male suffrage, and finally culminating in universal adult suffrage for all citizens.

Step-by-Step Solution

1
Identify the initial governance stage regarding voting rights.
Political systems originally featured absolute rule with a total absence of franchise.
Before constitutional reforms, citizens had no legal right to participate in electing government leaders.
2
Trace the introduction of limited voting qualifications.
Early representative systems introduced restricted franchise based on tax and property qualifications.
Suffrage was initially treated as a privilege reserved for wealthy property owners and taxpayers.
3
Identify the removal of economic property barriers for men.
Voting rights expanded to universal male suffrage, removing property requirements for men while continuing to disenfranchise women.
Gender restrictions persisted in electoral laws even after wealth requirements for male voters were abolished.
4
Determine the final stage of full franchise equality.
The progression concludes with universal adult suffrage, guaranteeing equal voting rights to all adult citizens.
Modern constitutional democracy requires non-discriminatory voting rights regardless of gender, wealth, or social standing.
