Explanation / Answer
1. Small amounts of alcohol act as a stimulant, reducing inhibition and producing feelings of mild euphoria while large amount of alcohol acts as a depressant, that slows brain and body reactions. So, option A is the correct answer.
2. Negative reinforcement (Option A) is the correct answer. In negative reinforcemnet, a response or behavior is strengthened by stopping, removing or avoiding a negative outcome or aversive stimulus.
