Question 1 of 10
A single farmer in a huge wheat market cannot change the wheat price because perfect competition has:
So many sellers of an identical product that one cannot affect price
Only one seller
Branded products
Government price-setting
Explanation: With countless sellers of a homogeneous good, each is a tiny price taker.
Question 2 of 10
At a price above equilibrium, the resulting surplus pushes the price:
Down toward equilibrium
Further up
To zero
Nowhere
Explanation: Unsold surplus makes sellers cut prices until the market clears at equilibrium.
Question 3 of 10
A bad harvest shifts the supply of onions left while demand is unchanged. The equilibrium price will:
Rise and quantity fall
Fall and quantity rise
Stay the same
Become zero
Explanation: Less supply at each price raises the equilibrium price and lowers the equilibrium quantity.
Question 4 of 10
A government fixes the price of a medicine below its equilibrium to keep it affordable. A likely result is:
A shortage, possibly with rationing or a black market
A surplus
No effect
Higher supply
Explanation: A binding price ceiling makes demand exceed supply, producing shortages that may trigger rationing or black markets.
Question 5 of 10
The MSP guarantees farmers a price above the market level. To prevent unsold surplus harming farmers, the government usually:
Buys up the surplus produce
Bans farming
Lowers the MSP to equilibrium
Ignores it
Explanation: Because a price floor creates a surplus, the government procures and stores the excess at the support price.
Question 6 of 10
Both an increase in demand and an increase in supply raise the equilibrium quantity, but they affect price differently: demand up raises price while supply up:
Lowers price
Also raises price
Leaves price unchanged always
Removes price
Explanation: More supply at each price lowers the equilibrium price even as quantity rises — opposite to a demand increase.
Question 7 of 10
A price ceiling only causes a shortage if it is set:
Below the equilibrium price
Above the equilibrium price
At the equilibrium price
At zero
Explanation: Only a ceiling below equilibrium is binding; one set above it has no effect.
Question 8 of 10
Free entry of firms in perfect competition means that, if existing firms earn high profits, new firms will:
Enter, raising supply and pushing price down
Be banned
Leave the market
Set the price
Explanation: Free entry lets newcomers chase profits, increasing supply until extra profits are competed away.
Question 9 of 10
If both demand and supply rise by the same amount, the equilibrium quantity rises and the equilibrium price:
Stays roughly unchanged
Always doubles
Falls to zero
Becomes negative
Explanation: The upward push of higher demand and downward push of higher supply on price roughly cancel, while quantity clearly rises.
Question 10 of 10
The whole point of demand–supply analysis is shown by price controls: a ceiling helps ____ and a floor helps ____.
Buyers; sellers
Sellers; buyers
No one; everyone
Government; no one
Explanation: A ceiling keeps prices low for buyers; a floor keeps prices high for sellers — each helps one side and creates an imbalance.
