Why is this statement wrong: "Economists argue that lower prices will result in fewer units being supplied. However, there are exceptions to this rule. For example, in 1972, a very simple 10-digit electronic calculator sold for $120. By 2000, the price of the same type of calculator had declined to less than $5. Yet business firms produced and sold many more calculators in 2000 than they did in 1971. Lower prices did not result in less production or in a decline in the number of calculators supplied."
1. The statement ignores changes in quantity demanded.
2. The statement ignores changes in tastes.
3. The statement ignores changes in demand.
