Given the task definition, example input & output, solve the new input case.
Given a document, an entity and its sentiment towards the entity, verify if it is the correct sentiment towards the entity. Answer should be yes or no. Note that URLs in the text have been replaced with [Link].
Example: Verify if the sentiment of the following document towards the entity Bill Clinton is Positive . Bill Clinton knows how to win friends and influence people. The former president is a master of reinvention — and the same talents that guided him into office have propelled him, more recently, into the stratosphere of Internet stardom.
Output: yes
Here the author of the document praises Bill for this ability to win friends. Hence the sentiment should be Positive and the answer is yes.

New input case for you: Verify if the sentiment of the following document towards the entity Christopher Foerster is Positive . If you wondered just how insane the NFL season would get  fans were treated to a video over the weekend that reportedly featured  former Dolphins offensive line coach Christopher Foerster  snorting what seemed to be cocaine while  he  whispered sweet somethings to a Las Vegas model who would later post that very video to  her  social media feed.
The reason  she  did such a thing was  in part  the ongoing national anthem controversy that continues to polarize a country.
 Foerster  took full responsibility for the video and has since resigned from  his  post with the Dolphins.
 He  states  via The Sun-Sentinel: âI am resigning from my position with the Miami Dolphins and accept full responsibility for my actions. I want to apologize to the organization and my sole focus is on getting the help that I need with the support of my family and medical professions.â
Output:
no
