Which of the following is NOT listed as affecting how quickly someone becomes intoxicated in the BBC discussion?

• A. Gender
• B. Body weight
• C. Water content
• D. Alcohol tolerance

Answer: (D)

The main idea is how the speed of intoxication is influenced by physical factors that affect alcohol distribution in the body. Body weight and water content determine how diluted alcohol is in the body's fluids, so a person with more body water or greater body mass will generally see a slower rise in blood alcohol concentration after a drink. Gender differences also play a role because of variations in body composition and metabolism that affect how quickly alcohol is processed.

Alcohol tolerance, however, describes how someone’s response to alcohol changes with repeated exposure. It affects how strong the effects feel at a given blood alcohol level, but it doesn’t change how fast alcohol is absorbed and distributed in the body. So it doesn’t influence the rate at which intoxication occurs, making it the factor not listed in the BBC discussion.
