equally
B) Economic decisions are made by individuals and businesses based on
supply and demand
,C) Traditional customs and beliefs determine production and
distribution methods
D) A central planning committee sets all prices and production quotas
Answer: B
Rationale: In a market economy, decentralized decisions by households
and firms interacting in markets drive resource allocation through
supply and demand mechanisms. Option A describes a
command/communist economy, Option C describes a traditional
economy, and Option D describes a command economy with central
planning .
Q2. When the Federal Reserve raises the discount rate, what is the
most likely immediate effect on the economy?
A) Increased consumer spending due to higher confidence
B) Decreased borrowing by commercial banks, leading to tighter money
supply
C) Immediate reduction in unemployment rates
D) Increased exports due to stronger domestic currency
Answer: B
Rationale: The discount rate is the interest rate the Fed charges banks
for short-term loans. Raising it makes borrowing costlier for banks,
reducing their reserves and tightening the money supply. Higher
discount rates typically reduce consumer spending and may increase
unemployment in the short run .
,Q3. Which scenario best illustrates the concept of opportunity cost?
A) A company spends $1 million on new equipment
B) A student chooses to study economics instead of working a part-time
job
C) The government increases taxes to fund infrastructure
D) A consumer buys a discounted item during a sale
Answer: B
Rationale: Opportunity cost is the value of the next best alternative
given up when making a choice. Here, the wages and experience from
the part-time job represent the opportunity cost of studying. The other
options describe capital expenditure, fiscal policy, or purchasing
decisions without explicitly identifying the trade-off .
Q4. In which market structure would you expect to find a single seller
with significant control over price and high barriers to entry?
A) Perfect competition
B) Monopolistic competition
C) Oligopoly
D) Monopoly
Answer: D
Rationale: A monopoly is defined by a single seller, a unique product
with no close substitutes, significant price control, and high barriers
preventing entry. Perfect competition features many sellers with no
price control; monopolistic competition has many sellers with
differentiated products; oligopoly features a few large firms .

Product (GDP) calculated using the expenditure approach?
A) Transfer payments like Social Security
B) Intermediate goods used in production
C) Business investment in capital goods
D) Sales of used goods
Answer: C
Rationale: The expenditure approach calculates GDP as Consumption +
Investment + Government Spending + Net Exports. Business investment
in capital goods (equipment, structures, inventory) is a direct
component. Transfer payments are excluded to avoid double-counting;
intermediate goods and used goods sales are excluded to prevent
multiple counting .
Q6. Which scenario below is an example of a command economy?
A) The government owns all major industries and sets production
targets for factories
B) Prices for consumer goods are determined by what people are willing
to pay
C) A group of investors starts a new technology company
D) A farmer decides what crops to plant based on expected market
prices

ownership of the means of production and central planning of output,
