Question 1: What does the law of demand state?
• A) As the price of a good increases, the demand for it increases.
• B) As the price of a good decreases, the demand for it decreases.
• C) As the price of a good increases, the demand for it decreases.
• D) Demand is not affected by price changes.
Correct Option: C
Rationale: The law of demand indicates that there is an inverse relationship between
the price of a good and the quantity demanded. When prices rise, consumers are likely
to purchase less of that good, leading to a decrease in demand, and vice versa.
Question 2: Which of the following is a characteristic of a monopoly?
• A) Many firms selling identical products.
• B) Single seller dominating the market.
• C) Easy entry and exit from the market.
• D) Perfect substitutes available.
Correct Option: B
Rationale: A monopoly is defined by the presence of a single seller in the market who
has significant control over the price and supply of a product. This contrasts with
perfect competition, where many sellers provide identical products, and there are no
barriers to entry.
Question 3: What is GDP?
• A) Gross Domestic Product, measuring total production in an economy.
• B) Gross Domestic Product, the monetary value of all finished goods and
services produced within a country's borders in a specific time period.
• C) General Demand Price, indicating consumer demand.
, • D) Gross Domestic Profit, measuring profits of companies.
Correct Option: B
Rationale: GDP stands for Gross Domestic Product and represents the total monetary
value of all final goods and services produced within a country during a specific period.
It is a key indicator of economic performance and health.
Question 4: What is the main purpose of fiscal policy?
• A) To influence the economy through government spending and taxation.
• B) To control inflation through interest rates.
• C) To regulate international trade.
• D) To manage the money supply directly.
Correct Option: A
Rationale: Fiscal policy involves the use of government spending and taxation to
influence the economy. By adjusting these levers, governments aim to achieve
economic objectives such as growth, unemployment reduction, and inflation control.
Question 5: What is the concept of opportunity cost?
• A) The total cost incurred in production.
• B) The price of the next best alternative foregone.
• C) The benefits of an option chosen over the next best alternative.
• D) The cost of resources used in production.
Correct Option: B
Rationale: Opportunity cost refers to the value of the next best alternative that is
foregone when a decision is made. It highlights the trade-offs involved in any economic
decision, emphasizing that every choice has a cost.
Question 6: What is meant by "elasticity of demand"?
• A) The measure of how much demand changes with a change in supply.
• B) The responsiveness of quantity demanded to a change in price.
• C) The extent to which consumers adjust their demand based on price
changes.
• D) The total demand for goods in an economy.
Correct Option: B
,Rationale: Elasticity of demand measures how sensitive consumers are to price
changes. If demand is elastic, a small change in price leads to a large change in quantity
demanded. Conversely, inelastic demand indicates that quantity demanded is less
responsive to price changes.
Question 7: Which of the following describes a negative externality?
• A) Increased production leads to higher prices for consumers.
• B) Pollution from a factory affecting the health of nearby residents.
• C) A new technology lowering production costs.
• D) A subsidy that encourages more production.
Correct Option: B
Rationale: A negative externality occurs when the actions of individuals or firms have
adverse effects on third parties. In this case, pollution from a factory negatively impacts
the health of nearby residents, representing an external cost not reflected in market
prices.
Question 8: What does the production possibility frontier (PPF) illustrate?
• A) The relationship between price and quantity supplied.
• B) The trade-offs between two goods that an economy can produce.
• C) The impact of inflation on production levels.
• D) The demand curve for a single product.
Correct Option: B
Rationale: The production possibility frontier (PPF) shows the maximum feasible
amount of two goods that an economy can produce with its available resources and
technology. It illustrates trade-offs and opportunity costs, highlighting the limits of
production.
Question 9: What is the primary goal of monetary policy?
• A) To increase government spending.
• B) To improve trade relations.
• C) To control inflation and stabilize the currency.
• D) To raise taxes to increase revenue.
, Correct Option: C
Rationale: The primary goal of monetary policy is to manage the economy's money
supply and interest rates to achieve macroeconomic objectives such as controlling
inflation, stabilizing the currency, and fostering economic growth.
Question 10: Which of the following is a likely consequence of a price ceiling?
• A) Surplus of goods available in the market.
• B) Shortages due to increased demand.
• C) Increased quality of products offered.
• D) Reduced demand as prices rise.
Correct Option: B
Rationale: A price ceiling, which sets a maximum price for a good, can lead to
shortages because demand often exceeds supply at that price. Producers may be
unwilling to sell at the lower price, leading to decreased availability of the product.
Question 11: What is a public good?
• A) A good that is sold at a high price.
• B) A good that is non-excludable and non-rivalrous.
• C) A good that is produced by private firms.
• D) A good that is subject to market competition.
Correct Option: B
Rationale: Public goods are characterized by being non-excludable (individuals cannot
be effectively excluded from use) and non-rivalrous (one person's use does not reduce
availability for others). Examples include national defense and public parks.
Question 12: What is the effect of an increase in consumer income on normal
goods?
• A) Demand decreases.
• B) Demand increases.
• C) Demand remains unchanged.
• D) Supply decreases.
Correct Option: B
