Verified step by step guidance

1. Understand that the problem is asking which factor influences the speed at which an individual feels the effects of alcohol when the amount and rate of drinking are held constant.
2. Recognize that the color of the alcoholic beverage and the brand of alcohol are unlikely to affect absorption rate significantly, as alcohol content and drinking rate are the same.
3. Consider the time of day: while it might influence alertness or mood, it does not directly affect how quickly alcohol is absorbed into the bloodstream.
4. Focus on physiological factors such as body weight, which affects the distribution of alcohol in the body. A person with lower body weight generally has less body water, leading to higher blood alcohol concentration (BAC) faster.
5. Conclude that body weight is the most relevant factor influencing how quickly an individual feels the effects of alcohol under the given conditions.
