Answer:
The discount rates were lowered

Discount rate is the rate that is used to determine the present value of future cash flows that will be spent in a project.
This is different from the cost of capital which is the amount that just meets the incurred cost of executing a project.
Discount rate determines of the benefits of the project are greater than the cost.
In the given scenario where benefits balance the cost, the project will be worthwhile is discount rate is lower.
That is there will be a lower cost of execution of the project so revenue will be higher than the cost
