No More Freebies<br>Tom moved to a new neighborhood. Tom noticed his new neighbor didn't have a password on his wi-fi. Tom began surfing off his neighbor's wi-fi service for free. One day Tom noticed his neighbor did secure his wi-fi with passwords. Tom then had to call the cable company and begin paying for service.
Tom's neighbour had to pay extra for wifi
The context does not say that Tom's neighbour knew that he was using his wifi, or caused extra chargers. So it is neither correct or incorrect to conclude that Tom's neighbour had to pay extra. It was probably difficult for the system to understand that this cannot be concluded from the context
