Can a person be impaired after consuming only 2 beers, and if so, who is most likely to be affected?

The scenario presented indicates that a person can indeed be impaired after consuming just two beers, particularly depending on certain factors such as body weight. When considering someone who weighs approximately 100 pounds, the alcohol content in two beers can significantly affect their blood alcohol concentration (BAC). Since lighter individuals have a lower volume of blood, they may experience quicker and more pronounced effects from alcohol consumption compared to heavier individuals.

The impairment is not solely a function of the number of drinks consumed, but rather how those drinks interact with an individual's body. Factors like body weight, food intake, and individual tolerance can vary greatly, but in this case, a person weighing around 100 pounds is more likely to be affected by just two beers, leading to impairment.

Other answer choices introduce considerations like heavy drinking, eating habits, and age, which both play a role but do not capture the focused aspect of how body weight can directly influence impairment from alcohol consumption. Thus, the emphasis on weight as a critical factor clarifies why the selected answer is accurate.
