Consider the question. Can we conclude from "A man uses a hose to clean a plaza." that "A groundskeeper is working."?
Options:
- yes
- no
- it is not possible to tell
 What is the step-by-step reasoning process to arrive at the answer: it is not possible to tell?
A man using a hose to clean a plaza does not mean the man is a groundskeeper not that he is working.
