. Let's assume that the area is growing, so the green belt is a binding constraint. The current rental rates will not change since they are determined by the current supply and demand for rental housing. Since there is likely to be an increase in demand in the future, the price of rental homes will increase as well. The increase in rental prices in the future will be capitalized into the price of current homes, thus resulting in higher home prices.

9. A.By banning fracking in the Marcellus Shale region, oil supply will decrease, as oil previously extracted from this region is no longer available. Oil prices will therefore rise.

B.When oil prices increase, gasoline costs also increase. If demand remains the same, gasoline prices will increase.

C.As residents move from buses and trains to cars and trucks due to urban sprawl, gasoline demand increases. Combined with the reduction in oil supply caused by the fracking ban, this increased demand leads to an increase in gasoline equilibrium prices. Supply and demand changes would impact equilibrium quantities depending on their magnitude.

10. A. Enforcement targets drug dealers because they have a greater impact on the drug supply chain. Targeting users may not reduce drug availability.

b. Decriminalization lowers penalty for drug offenses, reducing the cost to dealers, thereby increasing the quantity of drugs supplied.

c. There may be a rise in fatal overdoses because of reduced legal consequences, increased access to potent drugs, and a lack of support. ABOVE ALL JUST GRAPH REQUIRED
