Okay, then I believe that the answer would be rumors or newspapers. The rumor is now known as the Boston Massacre. There were only like 3 people killed, but the colonists made it seem like the British were murderers to spread the Patriotic belief. They spread these rumors through newspaper, so try both. Sorry, hope this helps!
Answer: Strengthening a behavior by contingently withdrawing something displeasing.
Explanation: Negative reinforcement refers to the strengthening and motivating the behavior by the elimination of the negative outcome or stimulus by means of stopping, removal, avoidance etc .
So, anything that is unpleasant or displeasing is withdrawn from the behavior.Other options are incorrect because behavior is not weakened by this act and no pleasing factors are removed from the behavior.
Sounds like a comet
