Practice Exam - Exam 2 - Study Case 2 -Q4

I don’t understand the problem raised in this question:

The project manager has evaluated the actual costs through the design development phase, which has just been completed.
Which of the following options should the project manager consider based on the state of the current budget?

The Design Development phase proposed budget is $32,200.00, and the current budget spent is $20,072.50. So, why is the correct answer to change the draftsman with another one with a lower hourly rate? It is not an understandable question because it does not pose a problem. Please can you explain what is the problem you are trying to point out with this question? Thanks
