Jeff will most likely behave aggressively because he expects to be disinhibited by alcohol.
Step-by-step explanation:
Blood Alcohol Concentration (BAC) refers to the amount of alcohol mixed in a person's blood. If the BAC of a person is 10%, his blood is mixed with one part of alcohol for every 1000 parts. California government declares that .08% or higher BAC of a person as legally drunk, and driving of vehicle with the prescribed BAC level is illegal.
Jeff consumed only nonalcoholic mixer and fruit juice, to maintain the blood alcohol level to a point of the legal driving limit. Jeff behaves aggressive to the person who spills a drink on his shoes because he tries himself to stay away from alcohol.
