Question

in the market for popcorn, if incomes increase, and popcorn is a normal good, this will result in:
○ movement along the demand curve to a smaller quantity demanded.
○ movement along the demand curve to a larger quantity demanded.
○ movement along the supply curve to a smaller quantity supplied.
○ movement along the supply curve to a larger quantity supplied.

question 6

a market is said to be in equilibrium when:
○ the buying intentions of all consumers are realized.
○ the quantity demanded equals the quantity supplied.
○ demand is fully satisfied at all alternative prices.
○ the supply intentions of all sellers are realized.

question 7

in a market, the equilibrium price is determined by:
○ the government.

Explanation:

First Question (Popcorn Market)

1. Recall the concept of normal goods: For a normal good, an increase in income leads to an increase in demand (a shift of the demand curve, not movement along). But wait, the options here are about movement along curves. Wait, maybe I misread. Wait, no—wait, the options are about movement along demand or supply curves. Wait, no, actually, when income increases for a normal good, the demand curve shifts right. But the options given are about movement along the curve (which is due to price change). Wait, maybe there's a mistake, but among the options, let's re - evaluate. Wait, no—wait, the first question's options: movement along demand or supply. Wait, no, the key is: for a normal good, income increase increases demand. But movement along the demand curve is due to price change. Wait, maybe the question has a typo, but among the options, the only one related to demand increase (even though it's movement along, which is incorrect in theory, but maybe the question is simplified). Wait, no—wait, normal good: income up → demand up. If we consider that maybe the price adjusts, leading to movement along the demand curve to a larger quantity demanded? Wait, no, movement along demand is price - quantity. But income change shifts demand. However, among the options, the second option: "movement along the demand curve to a larger quantity demanded" is the closest in the given options (even though theoretically it's a shift, but maybe the question is using "movement along" incorrectly or simplifying). Wait, no, maybe I made a mistake. Let's think again: The demand curve shows the relationship between price and quantity demanded, ceteris paribus (including income). When income increases (a non - price factor), the demand curve shifts right. At the original price, quantity demanded increases, which would lead to a shortage, then price rises, and we move along the new demand curve? No, movement along the curve is due to price change. So maybe the question is flawed, but among the options, the second option is the best fit as normal good + income up → more quantity demanded (even if the "movement along" is not accurate in strict theory, but among the given choices).

1. For the market equilibrium question (Question 6): The definition of market equilibrium is when the quantity demanded equals the quantity supplied. The other options are incorrect: "The buying intentions of all consumers are realized" is not true (some consumers may not buy at equilibrium price), "Demand is fully satisfied at all alternative prices" is wrong (equilibrium is at one price), and "The supply intentions of all sellers are realized" is also wrong (some sellers may not sell at equilibrium price).

1. For Question 7 (equilibrium price determination): The equilibrium price is determined by the interaction of demand and supply (the point where quantity demanded equals quantity supplied). The government does not determine it in a free market (except in cases of price controls, but generally, equilibrium price is from demand - supply interaction). But since the options are cut off, but assuming the options are like demand and supply, or other choices, but based on the visible part, if the option "The quantity demanded equals the quantity supplied" (for Question 6) is correct.

Answer:

• First Question (Popcorn): B. movement along the demand curve to a larger quantity demanded.
• Question 6: B. The quantity demanded equals the quantity supplied.
• (For Question 7, since the options are cut off, but if we assume the standard, equilibrium price is determined by the intersection of demand and supply curves, so if options include that, that would be the answer. But with the given visible part, we can only answer the first two questions fully.)
