c) The decreased reserve requirements increases the amount of funds the lending institutions can lend. This increases the money supply curve (and shifts the supply curve to the right). The demand curve for money stays the same, so the interest rate decreases.
d) The decreased money for current shopping increases the demand for money. The supply of money stays the same, so the interest rate increases.
e) The increased demand increases the demand for money. The supply curve doesn't move, so the interest rate increases.
