Question 1Business environment and markets

Which of the following best defines a market in the study of business?

  1. A group of firms that agree never to compete with each other
  2. A government department that sets prices for all products
  3. Any arrangement where buyers and sellers interact to exchange goods or services Correct answer.
  4. A place where only physical goods are exchanged between buyers and sellers

Explanation

A market exists wherever buyers and sellers come together to exchange goods or services, whether physically or online. It does not need a fixed location and can involve tangible or intangible products.

Question 2Business environment and markets

A café owner notices that when she raises the price of coffee, fewer customers buy it. Which economic concept does this illustrate?

  1. Economies of scale
  2. Market segmentation
  3. The law of supply
  4. The law of demand Correct answer.

Explanation

The law of demand states that, all else being equal, quantity demanded falls as price rises. The café's falling sales at higher prices reflect this inverse relationship.

Question 3Business environment and markets

Which of the following is a characteristic of a perfectly competitive market?

  1. Products are differentiated by strong brand loyalty
  2. There are many buyers and sellers trading homogeneous products Correct answer.
  3. A single firm controls the entire supply of the product
  4. Entry into the market is blocked by high legal barriers

Explanation

Perfect competition assumes many buyers and sellers, identical products, and free entry and exit. Because no single participant can influence price, firms are price takers.

Question 4Business environment and markets

What is the primary role of consumers in a market economy?

  1. To set production quotas for manufacturers
  2. To regulate the quality of imported goods
  3. To make purchasing decisions that signal demand to producers Correct answer.
  4. To determine the tax rates applied to businesses

Explanation

In a market economy, consumers' spending choices signal what goods and services producers should supply. This consumer sovereignty helps allocate resources through price signals.

Question 5Business environment and markets

Which of the following is an example of a business operating in the primary sector?

  1. A factory that assembles televisions
  2. A bank that provides home loans
  3. A firm that mines iron ore for export Correct answer.
  4. A consultancy that offers legal advice

Explanation

The primary sector involves extracting raw materials directly from nature, such as mining, farming, and fishing. Mining iron ore therefore belongs to the primary sector.

Question 6Business environment and markets

What does the term 'opportunity cost' mean for a business?

  1. The value of the next best alternative forgone when a choice is made Correct answer.
  2. The tax paid on profits earned during a financial year
  3. The cost of borrowing money from a financial institution
  4. The total money spent on producing a good

Explanation

Opportunity cost is the value of the next best alternative that is given up when resources are committed to one option. Businesses face it whenever they allocate scarce resources such as capital or labour.

Question 7Business environment and markets

Which of the following best describes the effect of a government subsidy paid to domestic farmers?

  1. It raises the cost of production and reduces supply
  2. It directly reduces consumer demand for farm products
  3. It lowers production costs and tends to increase supply Correct answer.
  4. It removes all competition from the agricultural market

Explanation

A subsidy is a payment that lowers producers' costs, encouraging them to supply more at each price. This shifts the supply curve to the right.

Question 8Business environment and markets

Which statement correctly distinguishes a good from a service?

  1. A good is intangible, while a service is tangible
  2. A good is tangible and can be stored, while a service is intangible and consumed as it is produced Correct answer.
  3. A good is produced only by government, while a service is produced only by firms
  4. A good is always free, while a service is always paid for

Explanation

Goods are tangible products that can often be stored and resold, whereas services are intangible and typically produced and consumed at the same time. This distinction affects how each is marketed and delivered.

Question 9Business environment and markets

A new competitor enters a local market and offers the same product at a lower price. How are existing firms most likely to respond?

  1. They will immediately exit the market without considering options
  2. They will increase prices to protect profit margins
  3. They will ignore the competitor because demand is fixed
  4. They may lower prices or improve product quality to retain customers Correct answer.

Explanation

When a new competitor offers lower prices, existing firms typically respond by cutting prices, improving quality, or adding value to keep customers. Competition tends to give consumers more choice and better value.

Question 10Business environment and markets

Which factor would most likely shift the demand curve for a product to the right?

  1. An increase in the price of a complementary good
  2. A fall in consumers' disposable income
  3. A rise in the price of the product itself
  4. A successful advertising campaign that raises consumer preference Correct answer.

Explanation

A successful advertising campaign increases consumer preference for a product, shifting demand to the right at every price. Changes in the product's own price cause movements along the demand curve, not shifts.

Question 11Business environment and markets

A firm producing 1,000 units has total costs of $20,000. If total costs rise to $22,000 when output increases to 1,200 units, what is the marginal cost of the extra 200 units?

  1. $2 per unit
  2. $10 per unit Correct answer.
  3. $18.33 per unit
  4. $22 per unit

Explanation

Marginal cost is the change in total cost divided by the change in output. Here, $2,000 divided by 200 units equals $10 per unit.

Question 12Business environment and markets

Which of the following best describes a monopoly market structure?

  1. Many small firms selling identical products with no barriers to entry
  2. A single firm supplying a product with no close substitutes and high barriers to entry Correct answer.
  3. A few large firms that dominate the market and watch each other's pricing
  4. Many firms selling differentiated products with easy entry and exit

Explanation

A monopoly exists when one firm supplies a product that has no close substitutes and barriers prevent other firms from entering. This gives the monopolist significant control over price.

Question 13Business environment and markets

An economy experiences a sustained rise in the general price level. Which term describes this situation?

  1. Inflation Correct answer.
  2. Deflation
  3. Depreciation
  4. Recession

Explanation

Inflation is a sustained increase in the general level of prices across an economy. It reduces the purchasing power of money over time.

Question 14Business environment and markets

Which of the following is most likely to be a positive effect of increased international trade on a domestic economy?

  1. Access to a wider variety of goods at competitive prices Correct answer.
  2. Permanent removal of all import regulations
  3. Complete elimination of domestic unemployment
  4. Guaranteed protection of all local industries

Explanation

International trade gives consumers access to a wider range of goods and often at more competitive prices due to specialisation. It can also create export opportunities for domestic firms.

Question 15Business environment and markets

A business decides to produce more of a product because the market price has risen. This decision reflects which economic principle?

  1. Diminishing returns
  2. Consumer sovereignty
  3. The law of demand
  4. The law of supply Correct answer.

Explanation

The law of supply states that producers are willing to supply more of a good as its price rises, all else being equal. Higher prices can increase profitability and encourage greater output.

Question 16Business environment and markets

Which of the following best explains why governments provide public goods such as street lighting?

  1. Consumers prefer to pay individually for each use of street lighting
  2. Public goods are non-excludable and non-rival, so markets tend to underprovide them Correct answer.
  3. Public goods are only produced during periods of economic growth
  4. Private firms always find public goods highly profitable

Explanation

Public goods are non-excludable and non-rival, meaning firms cannot easily charge users and one person's use does not reduce availability. As a result, markets tend to underprovide them, so governments often step in.

Question 17Business environment and markets

What is meant by 'market failure'?

  1. A situation where a market operates exactly as intended
  2. Any situation where a business makes a loss
  3. When the free market fails to allocate resources efficiently Correct answer.
  4. When consumers choose not to buy a product

Explanation

Market failure occurs when the free market does not allocate resources efficiently, leading to outcomes such as overproduction of pollution or underprovision of public goods. It is a reason governments intervene.

Question 18Business environment and markets

A firm in an oligopoly market considers whether to cut prices. Why might it hesitate?

  1. Because demand in oligopolies is always perfectly inelastic
  2. Because oligopolies have no barriers to entry
  3. Because rival firms may match the cut, leaving all firms with lower revenue Correct answer.
  4. Because price cuts are illegal in all oligopolies

Explanation

In an oligopoly, a few large firms are interdependent, so a price cut may prompt rivals to respond in kind. This can lead to a price war that reduces revenue for all firms.

Question 19Business environment and markets

Which of the following is an example of a business responding to a change in the legal environment?

  1. A restaurant changes its menu to comply with new food labelling laws Correct answer.
  2. A firm hires more staff during a seasonal peak
  3. A retailer increases its advertising budget
  4. A manufacturer buys additional machinery to raise output

Explanation

The legal environment includes laws and regulations that businesses must follow. Adjusting a menu to meet new labelling laws is a direct response to a change in that environment.

Question 20Business environment and markets

A government imposes a tariff on imported steel. What is the most likely short-term effect?

  1. Domestic steel prices fall because imports increase
  2. Imported steel becomes more expensive for domestic buyers Correct answer.
  3. Domestic consumers pay less for products made from steel
  4. Domestic steel producers face more foreign competition

Explanation

A tariff is a tax on imports that raises the price of imported goods for domestic buyers. This can protect domestic producers but tends to raise costs for industries using the imported input.

Question 21Business environment and markets

A small business faces rising interest rates on its business loan. Which effect is most likely?

  1. Its tax obligations are eliminated
  2. Its loan repayments decrease, freeing up cash
  3. Its customers automatically receive lower prices
  4. Its borrowing costs increase, reducing funds available for expansion Correct answer.

Explanation

Higher interest rates increase the cost of servicing variable-rate debt, which can reduce the cash a business has for investment or expansion. This makes borrowing less attractive.

Question 22Business environment and markets

Which of the following best explains how price acts as a signal in a market economy?

  1. Prices remain fixed so that businesses can plan with certainty
  2. Prices are set by consumers voting in elections
  3. Prices are only used to calculate government revenue
  4. Prices rise and fall to indicate scarcity or surplus, guiding producers and consumers Correct answer.

Explanation

In a market economy, prices respond to changes in supply and demand, signalling scarcity or surplus. Producers and consumers use these signals to decide what to produce and buy.

Question 23Business environment and markets

A firm's average total cost falls as it expands output over a wide range. This is best explained by:

  1. Market failure
  2. Economies of scale Correct answer.
  3. Diseconomies of scale
  4. The law of demand

Explanation

Economies of scale occur when average costs fall as output increases, often due to specialisation, bulk purchasing, or spreading fixed costs. This can give larger firms a cost advantage.

Question 24Business environment and markets

In a market where a negative externality such as pollution exists, what is the likely outcome without government intervention?

  1. The good is produced at the socially optimal level
  2. The market automatically corrects the externality through price signals
  3. The good is underproduced relative to the social optimum
  4. The good is overproduced because private costs are lower than social costs Correct answer.

Explanation

With a negative externality, producers consider only their private costs and ignore the external costs imposed on society. As a result, output tends to exceed the socially optimal level.

Question 25Business environment and markets

Two firms in an oligopoly decide to coordinate their prices rather than compete. Why is this behaviour a concern for regulators?

  1. It reduces competition and can lead to higher prices and reduced choice Correct answer.
  2. It automatically improves product quality
  3. It increases competition and lowers prices for consumers
  4. It has no effect on the market because consumers control prices

Explanation

Price coordination among competitors reduces the competitive pressure that normally keeps prices low. Regulators treat such collusion as anti-competitive because it can harm consumers through higher prices and less choice.

Question 26Business environment and markets

Which of the following best describes the law of demand?

  1. As supply rises, demand automatically rises
  2. As income rises, quantity demanded always falls
  3. As price rises, quantity demanded also rises
  4. As price rises, quantity demanded falls, all other factors held constant Correct answer.

Explanation

The law of demand states an inverse relationship between price and quantity demanded when all other influences are held constant. Consumers generally buy less of a product as its price increases because it becomes relatively more expensive.

Question 27Business environment and markets

A bakery's fixed costs include rent and insurance. Which statement about fixed costs is correct?

  1. They must be paid even when output is zero Correct answer.
  2. They equal the cost of raw ingredients
  3. They change directly with the number of loaves baked
  4. They only exist in the long run

Explanation

Fixed costs do not vary with the level of output in the short run, so they are incurred even if production stops. Rent and insurance are typical examples because the business owes them regardless of how much it produces.

Question 28Business environment and markets

Which of the following best defines a market?

  1. A physical building where goods are exchanged
  2. Any arrangement where buyers and sellers interact to exchange goods or services Correct answer.
  3. A group of firms that agree never to compete
  4. A government agency that sets prices

Explanation

A market exists wherever buyers and sellers interact to exchange a good or service, whether in person or online. It is defined by the interaction of demand and supply rather than by a physical location.

Question 29Business environment and markets

A business operates in a market with many small sellers, identical products and no barriers to entry. Which market structure is this?

  1. Monopolistic competition
  2. Perfect competition Correct answer.
  3. Oligopoly
  4. Monopoly

Explanation

Perfect competition is characterised by many buyers and sellers, homogeneous products, free entry and exit, and perfect information. Each firm is a price taker because no single seller can influence the market price.

Question 30Business environment and markets

Which of the following is a factor of production that earns rent as its return?

  1. Labour
  2. Enterprise
  3. Capital
  4. Land Correct answer.

Explanation

The four factors of production are land, labour, capital and enterprise, and each earns a distinct return. Land earns rent, labour earns wages, capital earns interest and enterprise earns profit.

Question 31Business environment and markets

A government removes a quota that previously limited the number of imported shoes. What is the most likely effect on the domestic shoe market?

  1. Import volumes fall and domestic prices rise
  2. Domestic producers gain market share immediately
  3. Import volumes rise and domestic prices face downward pressure Correct answer.
  4. The supply of shoes in the domestic market decreases

Explanation

A quota restricts the quantity of imports, so removing it allows more foreign shoes into the market. Greater supply increases competition, which tends to push domestic prices downward and raises import volumes.

Question 32Business environment and markets

Which of the following describes a business cycle downturn?

  1. A permanent shift in the structure of an industry
  2. A period of rising output, employment and incomes
  3. A period when economic activity slows and unemployment tends to rise Correct answer.
  4. A one-off increase in the price of a single product

Explanation

A downturn is a phase of the business cycle in which economic activity contracts, so output falls and unemployment typically rises. It is distinguished from a boom, where activity and employment expand.

Question 33Business environment and markets

Which of the following is a characteristic of monopolistic competition?

  1. Entry into the market is completely blocked
  2. There are many firms selling differentiated products Correct answer.
  3. Products are identical and firms are price takers
  4. A single firm supplies the entire market

Explanation

Monopolistic competition combines many sellers with product differentiation, such as branding or location differences. Because entry is relatively easy, firms earn only normal profits in the long run.

Question 34Business environment and markets

A café raises its coffee price from $4 to $5 and sales fall from 200 to 160 cups per day. Using the midpoint method, what is the price elasticity of demand?

  1. 0.5
  2. 2.0
  3. 0.25
  4. 1.0 Correct answer.

Explanation

The midpoint method divides the percentage change in quantity by the percentage change in price. Quantity changes by 40 over an average of 180, giving about 22.2 per cent, while price changes by $1 over an average of $4.50, giving about 22.2 per cent, so elasticity is approximately 1.0.

Question 35Business environment and markets

A firm sells 500 units at $10 each. Its total fixed costs are $1,500 and total variable costs are $2,000. What is the firm's profit?

  1. $500
  2. $1,500 Correct answer.
  3. $5,000
  4. $3,500

Explanation

Total revenue is 500 units multiplied by $10, which equals $5,000. Total costs are fixed costs of $1,500 plus variable costs of $2,000, giving $3,500, so profit is $5,000 minus $3,500, which is $1,500.

Question 36Business environment and markets

Why does the supply curve for most products slope upwards?

  1. Producers face lower costs as output expands
  2. Consumers buy more at higher prices
  3. Higher prices make additional production more profitable, attracting more supply Correct answer.
  4. Government regulations require higher output at higher prices

Explanation

An upward-sloping supply curve reflects that higher prices increase the incentive for firms to produce and sell more. As output expands, firms may also face rising marginal costs, so a higher price is needed to justify extra production.

Question 37Business environment and markets

A new technology lowers the cost of producing solar panels. How does this affect the market for solar panels?

  1. The supply curve shifts to the right and price tends to fall Correct answer.
  2. The demand curve shifts to the left
  3. There is a movement along the supply curve without a shift
  4. The supply curve shifts to the left and price rises

Explanation

A fall in production costs is a non-price determinant that increases supply at every price, shifting the supply curve right. The resulting surplus at the original price pushes the market price down and quantity traded up.

Question 38Business environment and markets

Which of the following is most likely to increase the price elasticity of demand for a product?

  1. Consumers spend a large share of their income on the product Correct answer.
  2. Consumers have very little time to adjust to a price change
  3. The product is a necessity with no alternatives
  4. The product has few close substitutes

Explanation

Demand is more elastic when the product takes a large share of a consumer's budget, because price changes then have a noticeable effect on spending. The availability of substitutes, the nature of the good and the time allowed to adjust also influence elasticity.

Question 39Business environment and markets

Two firms dominate an industry and each considers cutting prices to gain market share. Why is this decision difficult for each firm?

  1. Price cuts are illegal in all industries
  2. Demand is perfectly inelastic in an oligopoly
  3. Consumers never respond to price changes in concentrated markets
  4. Retaliation may trigger a price war that reduces profits for both firms Correct answer.

Explanation

In an oligopoly, each firm's decisions affect the others, creating strategic interdependence. A price cut may be matched quickly, leaving market shares largely unchanged while lowering profits across the industry.

Question 40Business environment and markets

A government introduces stricter environmental standards on factory emissions. Which response best reflects how a business adapts to this legal change?

  1. The business increases emissions to lower production costs
  2. The business ignores the rules because compliance is optional
  3. The business immediately exits the market in all cases
  4. The business invests in cleaner technology to meet the new standards Correct answer.

Explanation

Changes in the legal environment alter the rules under which firms operate, so businesses must adjust production methods to comply. Investing in cleaner technology allows the firm to meet the standards while continuing to operate.

Question 41Business environment and markets

Which of the following best explains why governments tax goods that generate negative externalities?

  1. To make producers bear part of the external cost and reduce output Correct answer.
  2. To increase the quantity consumed of those goods
  3. To eliminate all competition in the market
  4. To subsidise consumers who buy the good

Explanation

A tax on a good with negative externalities raises its private cost toward the true social cost. This reduces the quantity produced and consumed, bringing output closer to the socially optimal level.

Question 42Business environment and markets

A country's currency depreciates against the currencies of its trading partners. What is the most likely effect on its exports?

  1. Exports fall because domestic firms lose competitiveness
  2. Exports become cheaper for foreign buyers and may rise Correct answer.
  3. Exports become more expensive for foreign buyers and may fall
  4. Exports are unaffected because exchange rates do not influence trade

Explanation

A depreciation lowers the foreign-currency price of the country's goods, making its exports more competitive abroad. This price effect typically increases export volumes, although other factors such as demand conditions also matter.

Question 43Business environment and markets

Which of the following is most likely to increase labour productivity in a business?

  1. Hiring more workers while keeping output constant
  2. Increasing the number of hours worked without changing methods
  3. Providing workers with additional training and better equipment Correct answer.
  4. Reducing the amount of capital available to workers

Explanation

Labour productivity measures output per worker or per hour worked, so it rises when workers produce more with the same or fewer inputs. Training and better capital equipment raise the output each worker can generate.

Question 44Business environment and markets

A firm's marginal cost is below its average total cost. What happens to average total cost as output increases slightly?

  1. Average total cost stays exactly the same
  2. Average total cost becomes zero
  3. Average total cost rises
  4. Average total cost falls Correct answer.

Explanation

When marginal cost is below average total cost, the cost of the next unit is lower than the current average, so the average is pulled down. Average total cost falls until marginal cost equals it at the minimum point.

Question 45Business environment and markets

A government provides a cash payment to low-income households. Which of the following best describes the likely economic effect?

  1. It is a form of taxation on business profits
  2. It directly increases the nation's stock of capital
  3. It acts as a transfer payment that may increase consumption Correct answer.
  4. It reduces the purchasing power of recipients

Explanation

A cash payment to households is a transfer payment because it redistributes income without producing goods or services directly. Recipients are likely to spend part of it, which can increase consumption and aggregate demand.

Question 46Business environment and markets

A firm faces a price elasticity of demand of 0.4 for its product. If it raises its price, what is the most likely effect on total revenue?

  1. Total revenue will remain unchanged
  2. Total revenue will fall to zero
  3. Total revenue will rise because demand is inelastic Correct answer.
  4. Total revenue will fall because demand is elastic

Explanation

When demand is inelastic, the percentage fall in quantity sold is smaller than the percentage rise in price. As a result, the price increase raises total revenue even though fewer units are sold.

Question 47Business environment and markets

A firm's production creates pollution that affects nearby residents who are not compensated. Which concept best describes this situation?

  1. A public good because the pollution is non-excludable
  2. A positive externality because residents benefit
  3. A merit good because the firm provides employment
  4. A negative externality because a third party bears an uncompensated cost Correct answer.

Explanation

A negative externality arises when production or consumption imposes a cost on a third party that is not reflected in the market price. The residents bear the pollution cost without compensation, so the private cost to the firm is below the social cost.

Question 48Business environment and markets

In a perfectly competitive market, firms earn only normal profit in the long run. Why does this occur?

  1. Free entry and exit allow profits to be competed away Correct answer.
  2. Firms collude to set a common price
  3. Consumers refuse to pay above cost
  4. The government fixes prices at average cost

Explanation

Supernormal profits in the short run attract new firms because entry is unrestricted. As new firms enter, market supply increases and price falls until firms earn only normal profit, eliminating the incentive for further entry.

Question 49Business environment and markets

A government imposes a price ceiling below the equilibrium price. What is the most likely outcome?

  1. An increase in supply as producers respond to higher prices
  2. A surplus of the good as supply exceeds demand
  3. A shortage as quantity demanded exceeds quantity supplied Correct answer.
  4. No change because price ceilings do not affect markets

Explanation

A binding price ceiling below equilibrium prevents the price from rising to clear the market. At the lower price, quantity demanded exceeds quantity supplied, creating a shortage and potentially non-price rationing.

Question 50Business environment and markets

Which of the following best explains why a natural monopoly may be more efficient than several competing firms?

  1. Competition always raises prices for consumers
  2. Government regulation removes all costs of production
  3. Natural monopolies are protected by consumer choice
  4. High fixed costs mean average costs keep falling over a large range of output Correct answer.

Explanation

A natural monopoly arises where large fixed costs create substantial economies of scale, so average cost falls as output expands. A single firm serving the whole market can therefore produce at lower average cost than several smaller firms duplicating the infrastructure.
