Study Guide | Questions with Answers & RATIONALE
QUESTION 1
Which of the following best defines economics?
A. The study of how governments collect taxes
B. The study of how businesses maximize profits
C. The study of how individuals and societies allocate scarce resources
D. The study of international trade agreements
E. The study of how banks manage money supply
CORRECT ANSWER: C. The study of how individuals and societies allocate
scarce resources
RATIONALE: Economics is fundamentally the study of scarcity and choice. Because
resources such as land, labor, and capital are limited while human wants are unlimited,
individuals and societies must make decisions about how to allocate those resources
most efficiently. This core definition encompasses both microeconomics (individual
decisions) and macroeconomics (economy-wide decisions).
QUESTION 2
What is scarcity in economics?
A. A situation where goods are too expensive for consumers to buy
B. The condition where unlimited wants exceed limited resources
C. A government policy that limits production of certain goods
D. The shortage of money in the banking system
E. A temporary reduction in the supply of a product
CORRECT ANSWER: B. The condition where unlimited wants exceed limited
resources
,RATIONALE: Scarcity is the fundamental economic problem. Human wants and needs
are virtually unlimited, but the resources available to satisfy those wants — including
time, money, land, and labor — are finite. This gap between unlimited wants and limited
resources forces every individual, business, and government to make choices about
how to allocate what they have.
QUESTION 3
The term "opportunity cost" refers to:
A. The total financial cost of producing a good
B. The cost of raw materials used in production
C. The value of the next best alternative forgone when a choice is made
D. The cost of government regulations on businesses
E. The price difference between two competing products
CORRECT ANSWER: C. The value of the next best alternative forgone when a
choice is made
RATIONALE: Opportunity cost is one of the most important concepts in economics.
Every time a decision is made, something else must be given up. The opportunity cost
is the value of the best alternative that was not chosen. For example, if a student
chooses to study instead of working, the opportunity cost is the income they could have
earned. This concept applies to individuals, businesses, and governments alike.
QUESTION 4
Which of the following is an example of a factor of production?
A. Consumer demand
B. Government subsidies
C. Land
D. Tax revenue
E. Consumer price index
CORRECT ANSWER: C. Land
,RATIONALE: The four factors of production are land, labor, capital, and
entrepreneurship (sometimes listed as three: land, labor, and capital). Land refers to all
natural resources used in production, including soil, water, minerals, and forests. These
factors are the inputs used to produce goods and services in an economy.
QUESTION 5
A production possibilities curve (PPC) illustrates:
A. The relationship between price and quantity demanded
B. The maximum combination of two goods an economy can produce given its
resources
C. The total revenue earned by a firm at different output levels
D. The effect of inflation on purchasing power
E. The government's budget allocation for public services
CORRECT ANSWER: B. The maximum combination of two goods an economy
can produce given its resources
RATIONALE: The Production Possibilities Curve (PPC) shows all possible
combinations of two goods or services an economy can produce when all resources are
fully and efficiently employed. Points on the curve represent full efficiency, points inside
the curve represent underutilization of resources, and points outside the curve are
currently unattainable. The PPC also visually demonstrates opportunity cost —
producing more of one good means producing less of another.
QUESTION 6
What does it mean when an economy is operating inside its production possibilities
curve?
A. The economy is producing at maximum efficiency
B. The economy is experiencing technological advancement
C. Resources are being underutilized or are inefficiently allocated
D. The economy has exceeded its productive capacity
E. The economy is experiencing deflation
, CORRECT ANSWER: C. Resources are being underutilized or are inefficiently
allocated
RATIONALE: A point inside the PPC indicates that the economy is not using all its
available resources. This can be due to unemployment, idle machinery, or inefficient
allocation. The economy has the potential to produce more without acquiring additional
resources. Moving toward the curve would require better resource utilization, such as
reducing unemployment or improving efficiency.
QUESTION 7
Which economic system relies primarily on custom and tradition to answer the three
basic economic questions?
A. Market economy
B. Command economy
C. Mixed economy
D. Traditional economy
E. Socialist economy
CORRECT ANSWER: D. Traditional economy
RATIONALE: In a traditional economy, economic decisions — what to produce, how to
produce it, and for whom — are determined by customs, traditions, and cultural
practices that have been passed down through generations. These economies are often
found in rural, agrarian, or indigenous communities. While they provide stability and
social cohesion, they may be slow to adapt to change and innovation.
QUESTION 8
In a command economy, economic decisions are primarily made by:
A. Individual consumers and producers
B. A central authority or government
C. Supply and demand forces
D. International trade organizations
E. Corporate executives
