Diminishing marginal productivity begins when the additional output from adding another worker starts to decrease. From the table, the increase in total output from adding the fourth worker (from 18 to 28) is 10 units, but the increase from adding the fifth worker (from 28 to 35) is only 7 units, indicating diminishing marginal productivity starts with the hiring of the fifth worker.
