SECTION 1: BASIC ECONOMIC CONCEPTS
Q1. What is the fundamental economic problem that all societies face?
A. Unemployment B. Inflation C. Scarcity D. Recession E. Deficit spending
CORRECT ANSWER: C. Scarcity RATIONALE: Scarcity is the condition in
which human wants exceed the available resources. It is the foundational problem in
economics because resources are limited while human wants are unlimited, forcing
choices and trade-offs.
Q2. Opportunity cost is best defined as:
A. The monetary price of a good or service B. The total cost of producing a good C. The
value of the next best alternative forgone D. The cost of raw materials used in
production E. The tax imposed on a product
CORRECT ANSWER: C. The value of the next best alternative forgone
RATIONALE: Opportunity cost represents what you give up when making a decision.
It is not just the money spent, but the value of the best alternative that was not chosen.
Q3. A Production Possibilities Frontier (PPF) illustrates:
A. The maximum profit a firm can earn B. The trade-offs between two goods an
economy can produce given its resources C. The total demand for goods in a market D.
The relationship between price and quantity demanded E. How taxes affect consumer
spending
CORRECT ANSWER: B. The trade-offs between two goods an economy can
produce given its resources RATIONALE: The PPF shows all combinations of
,two goods that can be produced using available resources and technology fully and
efficiently, illustrating the concept of trade-offs and opportunity cost.
Q4. A point inside the PPF indicates:
A. Full employment of resources B. Allocative efficiency C. Productive inefficiency or
unemployment of resources D. An unattainable output level E. Technological
advancement
CORRECT ANSWER: C. Productive inefficiency or unemployment of
resources RATIONALE: A point inside (below) the PPF means the economy is
not using all of its resources efficiently — some resources are idle or being
misallocated.
Q5. Which of the following best describes a normative economic statement?
A. The unemployment rate rose to 6% last year B. A minimum wage increase will reduce
employment C. The government should increase spending on education D. GDP grew
by 2.5% in the last quarter E. Inflation was 3% last year
CORRECT ANSWER: C. The government should increase spending on
education RATIONALE: Normative statements involve value judgments about
what ought to be. They cannot be tested or proven with data alone. The word "should"
signals a normative claim.
Q6. Which of the following is a positive economic statement?
A. Workers deserve a higher minimum wage B. The rich should pay more taxes C. The
inflation rate is currently 4% D. Healthcare should be free for everyone E. Pollution
taxes are unfair to manufacturers
CORRECT ANSWER: C. The inflation rate is currently 4% RATIONALE:
Positive statements are objective and factual — they describe what is, not what ought to
be. They can be tested against real-world data.
Q7. The law of increasing opportunity costs states that:
A. Opportunity costs decrease as more of a good is produced B. Resources are
perfectly adaptable between uses C. As more of one good is produced, the opportunity
,cost of producing additional units rises D. All goods have the same opportunity cost E.
Technology reduces opportunity costs over time
CORRECT ANSWER: C. As more of one good is produced, the opportunity
cost of producing additional units rises RATIONALE: This law explains the
bowed-out (concave) shape of the PPF. Resources are not perfectly suited for all uses,
so shifting more resources toward one good becomes increasingly costly.
Q8. Which of the following would cause an outward shift of the PPF?
A. A decrease in the labor force B. Improved technology C. A natural disaster destroying
factories D. An increase in unemployment E. A reduction in government spending
CORRECT ANSWER: B. Improved technology RATIONALE: An outward
shift in the PPF indicates economic growth — the ability to produce more of both goods.
Improved technology allows greater output from the same amount of resources.
Q9. Economics is primarily the study of:
A. How governments control the money supply B. The stock market and investment
strategies C. How individuals and societies make choices under scarcity D. International
trade agreements E. Business management strategies
CORRECT ANSWER: C. How individuals and societies make choices under
scarcity RATIONALE: Economics is the social science that examines how people
allocate scarce resources to satisfy unlimited wants. It covers decision-making at
individual, business, and national levels.
Q10. Which of the following is an example of a capital resource?
A. A farmer's land B. A construction worker C. A factory machine D. Petroleum in the
ground E. An entrepreneur's idea
CORRECT ANSWER: C. A factory machine RATIONALE: Capital resources
are human-made tools, equipment, and machinery used in production. A factory
machine is a classic example of physical capital.
Q11. The concept of "ceteris paribus" in economics means:
, A. All variables change simultaneously B. All other things being equal or held constant
C. The market is in equilibrium D. Resources are efficiently allocated E. Government
intervention is absent
CORRECT ANSWER: B. All other things being equal or held constant
RATIONALE: Economists use ceteris paribus to isolate the effect of one variable by
assuming all other variables remain unchanged. This allows clearer analysis of cause-
and-effect relationships.
Q12. Microeconomics focuses on:
A. The overall level of prices in an economy B. Total national output and employment C.
Individual consumers, firms, and specific markets D. Monetary and fiscal policy E.
International trade balances
CORRECT ANSWER: C. Individual consumers, firms, and specific markets
RATIONALE: Microeconomics studies the behavior of individual economic units —
households, firms, and markets — and how they make decisions about resource
allocation.
Q13. Macroeconomics focuses on:
A. A single firm's pricing strategy B. Consumer preferences for specific goods C. The
economy as a whole, including GDP, inflation, and unemployment D. Supply and
demand in individual markets E. A specific industry's production costs
CORRECT ANSWER: C. The economy as a whole, including GDP, inflation,
and unemployment RATIONALE: Macroeconomics examines aggregate
variables such as total output, employment, price levels, and economic growth across
the entire economy.
Q14. Which of the following best represents an entrepreneurial resource?
A. A piece of farmland B. A drill press in a factory C. An individual who organizes
production and bears risk D. A skilled mechanic E. Oil reserves under the sea
