The Niagara Escarpment had a bumper apple crop this year, significantly increasing the supply of apples in Ontario. Given this information, choose the statement that correctly describes the effect on the apple market in Ontario.

Which of the following is consistent with the law of supply? ◦ Fewer passengers chose to travel by airplane after the terrorist strikes of 9/11. ◦ A reduction of the price of salt led to a 5 percent increase in the quantity of salt consumed. ◦ An increase in the market price of iPhones causes an increase in the production of iPhones. ◦ The province of Ontario has less grape regulation than the province of Quebec, and grape production is lower in the province of Quebec
