The word "produce" in part (3) is incorrect. The sentence is talking about the action of maximizing the production of percarbamide, so the correct noun form is "production" (not "produce," which is a verb).
The correct sentence should read: "After several rounds of trial and error, the researchers found they could maximise percarbamide production by holding the concentration of urea between 15% and 38%."
