Q1: Statement 1: Economics as a discipline is often considered a science.
Statement 2: As a science, it primarily deals with quantitative data and statistical models.
(a) Both statements are true.
(b) Both statements are false.
(c) Statement 1 is true, but Statement 2 is false.
(d) Statement 1 is false, but Statement 2 is true.
Ans: (c)
Explanation: Economics is regarded as a social science because it uses systematic methods to study human behaviour and economic phenomena. However, economics is not only quantitative; qualitative reasoning, institutional knowledge and theoretical models are also integral components. Hence Statement 1 is true and Statement 2 is overly narrow.
Q2: In microeconomics, the focus is on individual markets and players, whereas macroeconomics looks at the economy as a whole.
(a) True.
(b) False.
(c) True only for microeconomics.
(d) True only for macroeconomics.
Ans: (a)
Explanation: Microeconomics analyses individual units (consumers, firms, markets) and price formation; macroeconomics studies aggregate outcomes (GDP, inflation, unemployment). Both descriptions are standard and complementary.
Q3: Statement 1: A capitalist economy is characterized by private ownership and market forces.
Statement 2: A socialist economy relies heavily on government control and public ownership of resources.
(a) Both statements are true.
(b) Both statements are false.
(c) Statement 1 is true, but Statement 2 is false.
(d) Statement 1 is false, but Statement 2 is true.
Ans: (a)
Explanation: In practice many economies combine elements of both systems; historical and contemporary examples show degrees of public ownership and market activity rather than pure forms.
Q4: Statement 1: The Production Possibilities Frontier (PPF) represents various combinations of two goods that an economy can produce.
Statement 2: Points inside the PPF indicate efficient use of resources.
(a) Both statements are true.
(b) Both statements are false.
(c) Statement 1 is true, but Statement 2 is false.
(d) Statement 1 is false, but Statement 2 is true.
Ans: (c)
Explanation: Statement 1 correctly describes the PPF. Points inside the PPF represent inefficiency - some resources are unemployed or misallocated - while points on the PPF are efficient.
Q5: The law of increasing opportunity cost states that as production of a good increases, the opportunity cost of producing an additional unit rises.
(a) True.
(b) False.
Ans: (a)
Explanation: When resources are not perfectly adaptable between goods, reallocating resources to produce more of one good reduces production of the other increasingly, raising the opportunity cost.
Q6: Statement 1: In a mixed economy, the economic decisions are made by both the government and private sectors.
Statement 2: Mixed economies combine elements of capitalist and socialist systems.
(a) Both statements are true.
(b) Both statements are false.
(c) Statement 1 is true, but Statement 2 is false.
(d) Statement 1 is false, but Statement 2 is true.
Ans: (a)
Explanation: Mixed economies use market signals and private enterprise, while the government provides public goods, regulates markets and may own key industries. India is commonly described as a mixed economy.
Q7: Deductive reasoning in economics starts with a general hypothesis or theory and then moves to specific observations.
(a) True.
(b) False.
Ans: (a)
Explanation: Deduction begins with theory to derive testable predictions; these predictions are then compared with empirical observations. Induction works in the opposite direction.
Q8: The central economic problems of any society revolve around what to produce, how to produce, and for whom to produce.
(a) True.
(b) False.
Ans: (a)
Explanation: These addresses the core of resource allocation in economics and determine production patterns, techniques and distribution of output.
Q9: Statement 1: Capital-intensive techniques are more likely to be chosen in developed economies.
Statement 2: Labor-intensive techniques are preferred in developing economies with labor surplus.
(a) Both statements are true.
(b) Both statements are false.
(c) Statement 1 is true, but Statement 2 is false.
(d) Statement 1 is false, but Statement 2 is true.
Ans: (a)
Explanation: Factor endowment and relative factor costs shape technique choice. Developed economies with abundant capital and higher wages tend to adopt capital-intensive production; labour-abundant developing economies often select labour-intensive methods to exploit comparative advantage in labour.
Q10: The opportunity cost is the cost of the next best alternative foregone.
(a) True.
(b) False.
Ans: (a)
Explanation: Opportunity cost choosing one option implies giving up the benefits of the best alternative use of those resources.
Q11: The concept of elasticity in economics measures the responsiveness of one variable to changes in another variable.
(a) True
(b) False
Ans: (a)
Explanation: Elasticity quantifies responsiveness; examples include price elasticity of demand, income elasticity and cross-price elasticity. It informs taxation, pricing and welfare analysis.
Q12: Statement 1: Inflation is the rate at which the general level of prices for goods and services is rising.
Statement 2: Deflation is the decrease in the general price level of goods and services.
(a) Both statements are true
(b) Both statements are false
(c) Statement 1 is true, but Statement 2 is false
(d) Statement 1 is false, but Statement 2 is true
Ans: (a)
Explanation: Persistent deflation can be harmful by increasing real debt burdens and depressing demand; policy aims usually target low and stable positive inflation.
Q13: Gross Domestic Product (GDP) measures the total income earned by a nation's factors of production within a given time period.
(a) True
(b) False
Ans: (a)
Explanation: GDP measures production within national boundaries. Gross National Product (GNP) measures income earned by resident factors of production irrespective of location; GDP equals GNP plus net factor income from abroad (the sign depends on net inflows/outflows).
Q14: Statement 1: A monopoly exists when a specific person or enterprise is the only supplier of a particular commodity.
Statement 2: Monopolistic competition involves many firms selling products that are similar but not identical.
(a) Both statements are true
(b) Both statements are false
(c) Statement 1 is true, but Statement 2 is false
(d) Statement 1 is false, but Statement 2 is true
Ans: (a)
Explanation: A monopoly has a single seller with significant market power. Monopolistic competition features product differentiation and many competing firms; each firm has some degree of pricing power due to differentiation.
Q15: Fiscal policy is the use of government spending and taxation to influence the economy.
(a) True
(b) False
Ans: (a)
Explanation: Fiscal policy can be expansionary (increasing spending or cutting taxes) or contractionary (decreasing spending or raising taxes) and is used to stabilise output and inflation or to achieve redistribution objectives.
Q16: The Lorenz Curve is a graphical representation of income or wealth distribution in a society.
(a) True
(b) False
Ans: (a)
Explanation: The Lorenz Curve plots cumulative population share against cumulative income share. It visually shows inequality; mathematical measures (Gini coefficient) are derived from it for quantitative comparison.
Q17: Statement 1: Demand-pull inflation occurs when aggregate demand in an economy outpaces aggregate supply.
Statement 2: Cost-push inflation is caused by a drop in aggregate supply due to increased prices of inputs.
(a) Both statements are true
(b) Both statements are false
(c) Statement 1 is true, but Statement 2 is false
(d) Statement 1 is false, but Statement 2 is true
Ans: (a)
Explanation: Both statements describe standard causes of inflation. In practice inflation can have mixed causes and may also be influenced by expectations and supply shocks.
Q18: Marginal utility is the additional satisfaction a consumer gains from consuming one more unit of a good or service.
(a) True
(b) False
Ans: (a)
Explanation: Marginal utility typically declines as consumption increases (law of diminishing marginal utility), influencing downward-sloping demand curves and consumer equilibrium.
Q19: Comparative advantage is the ability of a country to produce a particular good at a lower marginal and opportunity cost than another country.
(a) True
(b) False
Ans: (a)
Explanation: Comparative advantage focuses on lower opportunity cost rather than absolute cost. Specialisation according to comparative advantage and trade can raise welfare for trading partners.
Q20: The Phillips Curve represents the relationship between the rate of inflation and the unemployment rate.
(a) True
(b) False
Ans: (a)
Explanation: The Phillips Curve historically showed an inverse short-run relationship between inflation and unemployment. Over the long run, expectations and structural factors can weaken this trade-off; policy responses must consider short- and long-run effects.
