4. The following diagram shows a farmer's choice between free time and grain before (A) and after (B) an improvement in technology. Based on this information, determine whether each of the following statements are true or false. (a) The MRT of the new feasible frontier at B is larger than the MRT of the old feasible frontier at A. This gives the farmer an incentive to take more free time after the technology improvement. (b) If the MRS of the indifference curve at B is larger than the MRS of the indifference curve at A, then this gives the farmer an incentive to take more free time after the technology improvement. (c) The farmer may choose a point on either side of B after the technology improvement. 100 FF FF 55 Quantity of grain consumed IC 0 16 24 Hours of free time per day
