Consider the question. Given the sentence "A man gesturing with his hands to a fair haired lady who is smiling." can we conclude that "A man and woman are sitting back to back."?
Options:
- yes
- it is not possible to tell
- no
 What is the step-by-step reasoning process to arrive at the answer: no?
In order to be gesturing and smiling at one another they must be face to face not back to back.
