The following appeared in a memo from the director of a large group of hospitals. "In a controlled laboratory study of liquid hand soaps, a concentrated solution of extra strength UltraClean hand soap produced a 40 percent greater reduction in harmful bacteria than did the liquid hand soaps currently used in our hospitals. During our recent test of regular-strength UltraClean with doctors, nurses, and visitors at our hospital in Worktown, the hospital reported significantly fewer cases of patient infection (a 20 percent reduction) than did any of 42 the other hospitals in our group. The explanation for the 20 percent reduction in patient infections is the use of UltraClean soap."

ultrasoap에 관한 문제인데요. Direction이 alternative explanations를 제시하라고 하는데 저는 1. 박테리아가 줄었다 2. 감염이 줄었다 이 논점에 대한 alternatives는 제시하겠는데 논점을 한가지 더 못잡겠더라구요. 어떤게 있을까요?
또한 argue에서 논점을 두가지만 제시할 경우에 3점 넘기가 어려울까요?
