choose one:
a. decrease; increase
b. decrease; decrease
c. increase; increase

The correct answer is option C.

Explanation:

A new technology that increases productivity by 30% will need more investment. This causes the overall equilibrium investment to increase. This need for investment will cause the investment demand curve to shift to the right.  

This rightward shift in the investment demand curve will cause the equilibrium interest rate to increase. So the equilibrium interest rate in the loanable funds market will increase.
