Consider the question. Given the sentence "A man in a suit and a large bag walking through the streets of the city." is it true that "Jack the ripper stalks his next victim through the streets while carrying his surgical kit."?
 What is the step-by-step reasoning process to arrive at the answer: it is not possible to tell?
Not all men in suits are Jack the Ripper. Not every large bag is a medical kit. That the man walks does not imply he stalks someone.
