Why are city gun buyback programs unlikely to work? Because the supply of guns in a city is very elastic, so more guns are brought in to meet the increase in demand from the gun buyback program. Because the supply of guns in a city is very inelastic, so the buyback program does not remove many guns from the street. Because the buyback program does not increase demand by enough to remove guns from the street. Because criminals do not behave rationally and so do not respond to incentives.
Because the supply of guns in a city is very elastic, so more guns are brought in to meet the increase in demand from the gun buyback program.

Every spring, motorists do more driving than during the winter months. Every spring, the price of gasoline increases and the motorists buy more gasoline. This experience suggests that the "law of supply" does not always hold for necessities like gasoline None of these answers are correct. "law of demand" does not always hold for necessities like gasoline. laws of supply and demand are both contradicted for gasoline, though only during the spring driving season.
None of these answers are correct.
The price of turkeys goes down at Thanksgiving even though demand increases because: Suppliers time the production of turkeys to match up with Thanksgiving, ensuring that higher demand is met. Supply increases by relatively more than demand because frozen turkeys are brought to market. Consumers don't actually like turkey and grocery stores know they won't buy it at higher prices. Suppliers are generous and want everyone to enjoy turkeys.

An article in the Wall Street Journal in early 2001 noted two developments in the market for laser eye surgery. The first development concerned side effects from the surgery, including blurred vision. The second development was that the companies renting eye-surgery machinery to doctors had reduced their charges. In the market for laser eye surgeries, these two developments decreased demand and decreased supply, resulting in a decrease in the equilibrium quantity and an increase in the equilibrium price of laser eye surgeries. decreased demand and increased supply resulting in an increase in both the equilibrium quantity and the equilibrium price of laser eye surgeries. decreased demand and increased supply, resulting in a decrease in the equilibrium price and an uncertain effect on the equilibrium quantity of laser eye surgeries. decreased demand and increased supply, resulting in a decrease in both the equilibrium price and the equilibrium quantity of laser eye surgeries.

Why aren't imports of roses from South America and Africa high year-round instead of just around Valentine's Day? Select all that apply. None of these apply. The spike in demand makes it profitable for producers with higher costs (like transportation) to enter the market. The government limits imported flowers except around Valentine's and Mothers' Day. Flower production in the US is particularly low in February, so US-based supply is shifted leftward that month because of the climate.
options 1 and 4
