Answer:
The loanable funds supply curve (S1) will not shift.
Step-by-step explanation:
When the interest rates change, it is similar to a change in the price of a good. In this case the good is money and the interest rate is its price. A change in the price of a good will result in a change of the quantity supplied along the supply curve, but it will not shift the entire curve, therefore the curve S1 remains the same.
