True

False

a) "A"

demand, right, supply, left, when price of substitue rise the demand curve will shift to the right but when price of substitue in production rises the supply curve will shift to the left.

b) True, at the point where the MR=MC the activity should stop.

c) "A"

the supply curve will shift to the left and the new equilibrium will be at a higher price and lower level of output.

d) All the factors willl shift the aggregate demand curve to the right and the new equilibrium will be at a higher price and higher level of output. The answer is "A".

e) False, both decrease the number of goods brought and sold in the market.
