Answer:
. b) verbally expressed their feelings of anger
Step-by-step explanation:
Since there was increased activity in the part of their brain when they were denied the opportunity to make money and that part of the brain is responsible for understanding personal emotions and making socially appropriate decisions, and making socially appropriate decisions, it is most likely that they verbally expressed their anger.
First, by understanding that they were angry and verbally expressing such emotion, it shows that that part of the brain responsible for understanding emotions and making acceptable social decisions was active.
They could have understood their emotions but not made a socially appropriate decision. They might have started physically to attack the person who denied them the chance of making money, but instead, they understood their emotions and did the most socially appropriate thing by verbally expressing their anger.
