Consider the question. Can we conclude from "Two white dogs chase after a red ball in a yard in front of a white fence." that "There are two dogs playing with each other."?
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?
Both dogs are chasing after a ball but this doesn't necessarily mean that they are playing with each other.
