This question makes a standard jump between percentage to total amount. All the stimulus says is that a higher percentage of the total expenditures are being spent on ineffective treatments. It does not automatically follow that less total money is being spent on effective treatments. For that to follow, you have to assume that total expenditures have either stayed the same or decreased. With that in mind, it's pretty clear which answer choice is correct.
